+.SH NAME
+find \- search for files in a directory hierarchy
+.SH SYNOPSIS
+.B find
+[\-H] [\-L] [\-P] [\-D debugopts] [\-Olevel] [starting-point...] [expression]
+.SH DESCRIPTION
+This manual page
+documents the GNU version of
+.BR find .
+GNU
+.B find
+searches the directory tree rooted at each given starting-point by
+evaluating the given expression from left to right, according to the
+rules of precedence (see section OPERATORS), until the outcome is
+known (the left hand side is false for \fIand\fR operations, true for
+\fIor\fR), at which point
+.B find
+moves on to the next file name.  If no starting-point is specified,
+`.' is assumed.
+.PP
+If you are using
+.B find
+in an environment where security is important (for example if you are
+using it to search directories that are writable by other users), you
+should read the "Security Considerations" chapter of the findutils
+documentation, which is called \fBFinding Files\fP and comes with
+findutils.   That document also includes a lot more detail
+and discussion than this manual page, so you may find it a more useful
+source of information.
+.SH OPTIONS
+The
+.BR \-H ,
+.B \-L
+and
+.B \-P
+options control the treatment of symbolic
+links.  Command-line arguments following these are taken to be names
+of files or directories to be examined, up to the first argument that
+begins with `\-', or the argument `(' or `!'.  That argument and any
+following arguments are taken to be the expression describing what is
+to be searched for.  If no paths are given, the current directory is
+used.  If no expression is given, the expression
+.B \-print
+is used
+(but you should probably consider using
+.B \-print0
+instead, anyway).
+.PP
+This manual page talks about `options' within the expression list.
+These options control the behaviour of
+.B find
+but are specified immediately after the last path name.  The five
+`real' options
+.BR \-H ,
+.BR \-L ,
+.BR \-P ,
+.B  \-D
+and
+.B  \-O
+must appear before
+the first path name, if at all.  A double dash
+.B \-\-
+can also be used
+to signal that any remaining arguments are not options (though
+ensuring that all start points begin with either `./' or `/' is
+generally safer if you use wildcards in the list of start points).
+.IP \-P
+Never follow symbolic links.  This is the default behaviour.  When
+.B find
+examines or prints information a file, and the file is a symbolic
+link, the information used shall be taken from the properties of the
+symbolic link itself.
+
+.IP \-L
+Follow symbolic links.  When
+.B find
+examines or prints information about files, the information used shall
+be taken from the properties of the file to which the link points, not
+from the link itself (unless it is a broken symbolic link or
+.B find
+is unable to examine the file to which the link points).  Use of this
+option implies
+.BR \-noleaf .
+If you later use the
+.B \-P
+option,
+.B \-noleaf
+will still be in effect.  If
+.B \-L
+is in effect and
+.B find
+discovers a symbolic link to a subdirectory during its search,
+the subdirectory pointed to by the symbolic link will be searched.
+.IP
+When the
+.B \-L
+option is in effect, the
+.B \-type
+predicate will always
+match against the type of the file that a symbolic link points to
+rather than the link itself (unless the symbolic link is broken).
+Actions that can cause symbolic links to become broken while
+.B find
+is executing (for example
+.BR \-delete )
+can give rise to confusing behaviour.
+Using
+.B \-L
+causes the
+.B \-lname
+and
+.B \-ilname
+predicates always to return
+false.
+
+.IP \-H
+Do not follow symbolic links, except while processing the command
+line arguments.  When
+.B find
+examines or prints information about files, the information used
+shall be taken from the properties of the symbolic link itself.   The
+only exception to this behaviour is when a file specified on the
+command line is a symbolic link, and the link can be resolved.  For
+that situation, the information used is taken from whatever the link
+points to (that is, the link is followed).  The information about the
+link itself is used as a fallback if the file pointed to by the
+symbolic link cannot be examined.  If
+.B \-H
+is in effect and one of the
+paths specified on the command line is a symbolic link to a directory,
+the contents of that directory will be examined (though of course
+\-maxdepth 0 would prevent this).
+.P
+If more than one of
+.BR \-H ,
+.B \-L
+and
+.B \-P
+is specified, each overrides the
+others; the last one appearing on the command line takes effect.
+Since it is the default, the
+.B \-P
+option should be considered to be in
+effect unless either
+.B \-H
+or
+.B \-L
+is specified.
+
+GNU
+.B find
+frequently stats files during the processing of the command line
+itself, before any searching has begun.  These options also affect how
+those arguments are processed.  Specifically, there are a number of
+tests that compare files listed on the command line against a file we
+are currently considering.  In each case, the file specified on the
+command line will have been examined and some of its properties will
+have been saved.  If the named file is in fact a symbolic link, and
+the
+.B \-P
+option is in effect (or if neither
+.B \-H
+nor
+.B \-L
+were specified), the information used for the comparison will be taken from
+the properties of the symbolic link.  Otherwise, it will be taken from
+the properties of the file the link points to.  If
+.B find
+cannot follow the link (for example because it has insufficient
+privileges or the link points to a nonexistent file) the properties of
+the link itself will be used.
+.P
+When the
+.B \-H
+or
+.B \-L options are in effect, any symbolic links listed
+as the argument of
+.B \-newer
+will be dereferenced, and the timestamp
+will be taken from the file to which the symbolic link points.  The
+same consideration applies to
+.BR \-newerXY ,
+.B \-anewer
+and
+.BR \-cnewer .
+
+The
+.B \-follow
+option has a similar effect to
+.BR \-L ,
+though it takes
+effect at the point where it appears (that is, if
+.B \-L
+is not used but
+.B \-follow
+is, any symbolic links appearing after
+.B \-follow
+on the
+command line will be dereferenced, and those before it will not).
+
+.IP "\-D debugoptions"
+Print diagnostic information; this can be helpful to diagnose problems
+with why
+.B find
+is not doing what you want.  The list of debug options should be comma
+separated.  Compatibility of the debug options is not guaranteed
+between releases of findutils.  For a complete list of valid debug
+options, see the output of
+.B find \-D
+.BR help .
+Valid debug options include
+.RS
+.IP help
+Explain the debugging options
+.IP tree
+Show the expression tree in its original and optimised form.
+.IP stat
+Print messages as files are examined with the
+.B stat
+and
+.B lstat
+system calls.  The
+.B find
+program tries to minimise such calls.
+.IP opt
+Prints diagnostic information relating to the optimisation of the
+expression tree; see the \-O option.
+.IP rates
+Prints a summary indicating how often each predicate succeeded or
+failed.
+.RE
+.IP \-Olevel
+Enables query optimisation.   The
+.B find
+program reorders tests to speed up execution while preserving the
+overall effect; that is, predicates with side effects are not
+reordered relative to each other.  The optimisations performed at each
+optimisation level are as follows.
+.RS
+.IP 0
+Equivalent to optimisation level 1.
+.IP 1
+This is the default optimisation level and corresponds to the
+traditional behaviour.  Expressions are reordered so that tests based
+only on the names of files (for example
+.B \-name
+and
+.BR \-regex )
+are performed first.
+.IP 2
+Any
+.B \-type
+or
+.B \-xtype
+tests are performed after any tests based only on the names of files,
+but before any tests that require information from the inode.  On many
+modern versions of Unix, file types are returned by
+.B readdir()
+and so these predicates are faster to evaluate than predicates which
+need to stat the file first.
+If you use the
+.B \-fstype
+.I FOO
+predicate and specify a filesystem type
+.I FOO
+which is not known (that is, present in `/etc/mtab') at the time
+.B find
+starts, that predicate is equivalent to
+.BR \-false .
+.IP 3
+At this optimisation level, the full cost-based query optimiser is
+enabled.  The order of tests is modified so that cheap (i.e.\& fast)
+tests are performed first and more expensive ones are performed later,
+if necessary.  Within each cost band, predicates are evaluated earlier
+or later according to whether they are likely to succeed or not.  For
+.BR \-o ,
+predicates which are likely to succeed are evaluated earlier, and for
+.BR \-a ,
+predicates which are likely to fail are evaluated earlier.
+.RE
+.IP
+The cost-based optimiser has a fixed idea of how likely any given test
+is to succeed.  In some cases the probability takes account of the
+specific nature of the test (for example,
+.B \-type f
+is assumed to be more likely to succeed than
+.BR "\-type c" ).
+The cost-based optimiser is currently being evaluated.   If it does
+not actually improve the performance of
+.BR find ,
+it will be removed again.  Conversely, optimisations that prove to be
+reliable, robust and effective may be enabled at lower optimisation
+levels over time.  However, the default behaviour (i.e.\& optimisation
+level 1) will not be changed in the 4.3.x release series.  The
+findutils test suite runs all the tests on
+.B find
+at each optimisation level and ensures that the result is the same.
+.P
+.SH EXPRESSION
+The part of the command line after the list of starting points is the
+.IR expression .
+This is a kind of query specification describing how we match files
+and what we do with the files that were matched.
+An expression is composed of a sequence of things:
+
+.IP Tests
+Tests return a true or false value, usually on the basis of some
+property of a file we are considering.  The
+.B \-empty
+test for example is true only when the current file is empty.
+
+.IP Actions
+Actions have side effects (such as printing something on the standard
+output) and return either true or false, usually based on whether or
+not they are successful.  The
+.B \-print
+action for example prints the name of the current file on the standard
+output.
+
+.IP "Global options"
+Global options affect the operation of tests and actions specified on
+any part of the command line.  Global options always return true.  The
+.B \-depth
+option for example makes
+.B find
+traverse the file system in a depth-first order.
+
+.IP "Positional options"
+Positional optiona affect only tests or actions which follow them.
+Positional options always return true.  The
+.B \-regextype
+option for example is positional, specifying the regular expression
+dialect for regulat expressions occurring later on the command line.
+
+.IP Operators
+Operators join together the other items within the expression.  They
+include for example
+.B \-o
+(meaning logical OR) and
+.B \-a
+(meaning logical AND).  Where an operator is missing,
+.B \-a
+is assumed.
+
+.P
+If the whole expression contains no actions other than
+.B \-prune
+or
+.BR \-print ,
+.B \-print
+is performed on all files for which the whole expression is true.
+
+The
+.B \-delete
+action also acts like an option (since it implies
+.BR \-depth ).
+
+.SS POSITIONAL OPTIONS
+Positional options always return true.  They affect only tests occurring
+later on the command line.
+
+.IP \-daystart
+Measure times (for
+.BR \-amin ,
+.BR \-atime ,
+.BR \-cmin ,
+.BR \-ctime ,
+.BR \-mmin ,
+and
+.BR \-mtime )
+from the beginning of today rather than from 24 hours ago.  This
+option only affects tests which appear later on the command line.
+
+.IP \-follow
+Deprecated; use the
+.B \-L
+option instead.  Dereference symbolic links.
+Implies
+.BR \-noleaf .
+The
+.B \-follow
+option affects only those tests which
+appear after it on the command line.  Unless the
+.B \-H
+or
+.B \-L
+option has
+been specified, the position of the
+.B \-follow
+option changes the behaviour of the
+.B \-newer
+predicate; any files listed as the argument
+of
+.B \-newer
+will be dereferenced if they are symbolic links.  The same
+consideration applies to
+.BR \-newerXY ,
+.B \-anewer
+and
+.BR \-cnewer .
+Similarly, the
+.B \-type
+predicate will always match against the type of the file
+that a symbolic link points to rather than the link itself.  Using
+.B \-follow
+causes the
+.B \-lname and
+.B \-ilname
+predicates always to return false.
+
+.IP "\-regextype \fItype\fR"
+Changes the regular expression syntax understood by
+.B \-regex
+and
+.B \-iregex
+tests which occur later on the command line.  To see which regular
+expression types are known, use
+.B -regextype
+.BR help .
+The Texinfo documentation (see
+.B SEE
+.BR ALSO )
+explains the meaning of and
+differences between the various types of regular expression.
+
+.IP "\-warn, \-nowarn"
+Turn warning messages on or off.  These warnings apply only to the
+command line usage, not to any conditions that
+.B find
+might encounter when it searches directories.  The default behaviour
+corresponds to
+.B \-warn
+if standard input is a tty, and to
+.B \-nowarn
+otherwise.  If a warning message relating to command-line usage is
+produced, the exit status of
+.B find
+is not affected.  If the POSIXLY_CORRECT environment variable is set,
+and
+.B \-warn is also used, it is not specified which, if any, warnings will be active.
+
+.SS GLOBAL OPTIONS
+Global options always return true.
+Global options take effect even for tests which occurr earlier on the
+command line.  To prevent confusion, global options should specified
+on the command-line after the list of start points, just before the
+first test, positional option or action. If you specify a global
+option in some other place,
+.B find
+will issue a warning message explaining that this can be confusing.
+
+The global options occur after the list of start points, and so are
+not the same kind of option as
+.BR \-L ,
+for example.
+
+.IP \-d
+A synonym for \-depth, for compatibility with FreeBSD, NetBSD, MacOS X and OpenBSD.
+
+.IP \-depth
+Process each directory's contents before the directory itself.  The
+\-delete action also implies
+.BR \-depth .
+
+.IP "\-help, \-\-help"
+Print a summary of the command-line usage of
+.B find
+and exit.
+
+.IP \-ignore_readdir_race
+Normally, \fBfind\fR will emit an error message when it fails to stat a file.
+If you give this option and a file is deleted between the time \fBfind\fR
+reads the name of the file from the directory and the time it tries to stat
+the file, no error message will be issued.    This also applies to files
+or directories whose names are given on the command line.  This option takes
+effect at the time the command line is read, which means that you cannot search
+one part of the filesystem with this option on and part of it with this option
+off (if you need to do that, you will need to issue two \fBfind\fR commands
+instead, one with the option and one without it).
+
+.IP "\-maxdepth \fIlevels\fR"
+Descend at most \fIlevels\fR (a non-negative integer) levels of
+directories below the starting-points.
+.B \-maxdepth 0
+ means only apply the tests and actions to the starting-points themselves.
+
+.IP "\-mindepth \fIlevels\fR"
+Do not apply any tests or actions at levels less than \fIlevels\fR (a
+non-negative integer).
+.B \-mindepth 1
+means process all files except the starting-points.
+
+.IP \-mount
+Don't descend directories on other filesystems.  An alternate name for
+.BR \-xdev ,
+for compatibility with some other versions of
+.BR find .
+
+.IP \-noignore_readdir_race
+Turns off the effect of
+.BR \-ignore_readdir_race .
+
+.IP "\-noleaf"
+Do not optimize by assuming that directories contain 2 fewer
+subdirectories than their hard link count.  This option is needed when
+searching filesystems that do not follow the Unix directory-link
+convention, such as CD-ROM or MS-DOS filesystems or AFS volume mount
+points.  Each directory on a normal Unix filesystem has at least 2
+hard links: its name and its `.'  entry.  Additionally, its
+subdirectories (if any) each have a `..\&' entry linked to that
+directory.  When
+.B find
+is examining a directory, after it has statted 2 fewer subdirectories
+than the directory's link count, it knows that the rest of the entries
+in the directory are non-directories (`leaf' files in the directory
+tree).  If only the files' names need to be examined, there is no need
+to stat them; this gives a significant increase in search speed.
+
+.IP "\-version, \-\-version"
+Print the \fBfind\fR version number and exit.
+
+.IP \-xdev
+Don't descend directories on other filesystems.
+
+.SS TESTS
+Some tests, for example
+.B \-newerXY
+and
+.BR -samefile ,
+allow comparison between the file currently being examined and some
+reference file specified on the command line.  When these tests are
+used, the interpretation of the reference file is determined by the
+options
+.BR \-H ,
+.B \-L
+and
+.B \-P
+and any previous
+.BR \-follow ,
+but the reference file is only examined once, at the time the command
+line is parsed.  If the reference file cannot be examined (for
+example, the
+.BR stat (2)
+system call fails for it), an error message is issued, and
+.B find
+exits with a nonzero status.
+.P
+Numeric arguments can be specified as
+.IP \fI+n\fP
+for greater than
+.IR n ,
+.IP \fI\-n\fP
+for less than
+.IR n ,
+.IP \fIn\fP
+for exactly
+.IR n .

+
+.IP "\-amin \fIn\fR"
+File was last accessed \fIn\fR minutes ago.
+
+.IP "\-anewer \fIfile\fR"
+File was last accessed more recently than \fIfile\fR was modified.  If
+\fIfile\fR is a symbolic link and the
+.B \-H
+option or the
+.B \-L
+option is in effect, the access time of the file it points to is
+always used.
+
+.IP "\-atime \fIn\fR"
+File was last accessed \fIn\fR*24 hours ago.
+When find figures out how many 24-hour periods ago the file
+was last accessed, any fractional part is ignored, so to match
+.B \-atime
+.BR +1 ,
+a file has to have been accessed at least
+.I two
+days ago.
+
+.IP "\-cmin \fIn\fR"
+File's status was last changed \fIn\fR minutes ago.
+
+.IP "\-cnewer \fIfile\fR"
+File's status was last changed more recently than \fIfile\fR was
+modified.  If \fIfile\fR is a symbolic link and the
+.B \-H
+option or the
+.B \-L
+option is in effect, the status-change time of the file it points
+to is always used.
+
+.IP "\-ctime \fIn\fR"
+File's status was last changed \fIn\fR*24 hours ago.
+See the comments for
+.B \-atime
+to understand how rounding affects the interpretation of file status
+change times.
+
+.IP \-empty
+File is empty and is either a regular file or a directory.
+
+.IP \-executable
+Matches files which are executable and directories which are
+searchable (in a file name resolution sense).  This takes into account
+access control lists and other permissions artefacts which the
+.B \-perm
+test ignores.  This test makes use of the
+.BR access (2)
+system call, and so can be fooled by NFS servers which do UID
+mapping (or root-squashing), since many systems implement
+.BR access (2)
+in the client's kernel and so cannot make use of the UID mapping
+information held on the server.  Because this test is based only on
+the result of the
+.BR access (2)
+system call, there is no guarantee that a file for which this test
+succeeds can actually be executed.
+
+.IP \-false
+Always false.
+
+.IP "\-fstype \fItype\fR"
+File is on a filesystem of type \fItype\fR.  The valid filesystem
+types vary among different versions of Unix; an incomplete list of
+filesystem types that are accepted on some version of Unix or another
+is: ufs, 4.2, 4.3, nfs, tmp, mfs, S51K, S52K.  You can use
+.B \-printf
+with the %F directive to see the types of your filesystems.
+
+.IP "\-gid \fIn\fR"
+File's numeric group ID is \fIn\fR.
+
+.IP "\-group \fIgname\fR"
+File belongs to group \fIgname\fR (numeric group ID allowed).
+
+.IP "\-ilname \fIpattern\fR"
+Like
+.BR \-lname ,
+but the match is case insensitive.
+If the
+.B \-L
+option or the
+.B \-follow
+option is in effect, this test returns false unless the symbolic link
+is broken.
+
+
+.IP "\-iname \fIpattern\fR"
+Like
+.BR \-name ,
+but the match is case insensitive.  For example, the
+patterns `fo*' and `F??' match the file names `Foo', `FOO', `foo',
+`fOo', etc.   The pattern `*foo*` will also match a file
+called '.foobar'.
+
+.IP "\-inum \fIn\fR"
+File has inode number \fIn\fR.  It is normally easier to use the
+.B \-samefile
+test instead.
+
+.IP "\-ipath \fIpattern\fR"
+Like
+.BR \-path .
+but the match is case insensitive.
+
+.IP "\-iregex \fIpattern\fR"
+Like
+.BR \-regex ,
+but the match is case insensitive.
+
+.IP "\-iwholename \fIpattern\fR"
+See \-ipath.  This alternative is less portable than
+.BR \-ipath .
+
+.IP "\-links \fIn\fR"
+File has \fIn\fR links.
+
+.IP "\-lname \fIpattern\fR"
+File is a symbolic link whose contents match shell pattern
+\fIpattern\fR.  The metacharacters do not treat `/' or `.' specially.
+If the
+.B \-L
+option or the
+.B \-follow
+option is in effect, this test returns false unless the symbolic link
+is broken.
+
+.IP "\-mmin \fIn\fR"
+File's data was last modified \fIn\fR minutes ago.
+
+.IP "\-mtime \fIn\fR"
+File's data was last modified \fIn\fR*24 hours ago.
+See the comments for
+.B \-atime
+to understand how rounding affects the interpretation of file
+modification times.
+
+.IP "\-name \fIpattern\fR"
+Base of file name (the path with the leading directories removed)
+matches shell pattern \fIpattern\fR.  Because the leading directories
+are removed, the file names considered for a match with
+.B \-name
+will never include a slash, so `\-name a/b' will never match anything
+(you probably need to use
+.B \-path
+instead).  A warning is issued if you try to do this, unless the environment variable
+POSIXLY_CORRECT is set.
+The metacharacters (`*', `?',
+and `[]') match a `.' at the start of the base name (this is a change
+in findutils-4.2.2; see section STANDARDS CONFORMANCE below).  To ignore a
+directory and the files under it, use
+.BR \-prune ;
+see an example in the
+description of
+.BR \-path .
+Braces are not recognised as being
+special, despite the fact that some shells including Bash imbue braces
+with a special meaning in shell patterns.  The filename matching is
+performed with the use of the
+.BR fnmatch (3)
+library function.   Don't forget to enclose the pattern in quotes
+in order to protect it from expansion by the shell.
+
+.IP "\-newer \fIfile\fR"
+File was modified more recently than \fIfile\fR.  If \fIfile\fR is a
+symbolic link and the
+.B \-H
+option or the
+.B \-L
+option is in effect, the
+modification time of the file it points to is always used.
+
+.IP "\-newerXY \fIreference\fR"
+Succeeds if timestamp \fIX\fR of the file being considered is newer
+than timestamp \fIY\fR of the file \fIreference\fR.   The letters
+\fIX\fR and \fIY\fR can be any of the following letters:
+
+.TS
+ll
+ll
+ll
+ll
+llw(2i).
+a	The access time of the file \fIreference\fR
+B	The birth time of the file \fIreference\fR
+c	The inode status change time of \fIreference\fR
+m	The modification time of the file \fIreference\fR
+t	\fIreference\fR is interpreted directly as a time
+.TE
+
+Some combinations are invalid; for example, it is invalid for
+.I X
+to be
+.IR t .
+Some combinations are not implemented on all systems; for example
+.I B
+is not supported on all systems.  If an invalid or unsupported
+combination of
+.I XY
+is specified, a fatal error results.  Time specifications are
+interpreted as for the argument to the
+.B \-d
+option of GNU
+.BR date .
+If you try to use the birth time of a reference file, and the birth
+time cannot be determined, a fatal error message results.  If you
+specify a test which refers to the birth time of files being examined,
+this test will fail for any files where the birth time is unknown.
+
+.IP \-nogroup
+No group corresponds to file's numeric group ID.
+
+.IP \-nouser
+No user corresponds to file's numeric user ID.
+
+.IP "\-path \fIpattern\fR"
+File name matches shell pattern \fIpattern\fR.  The metacharacters do
+not treat `/' or `.' specially; so, for example,
+.br
+.in +1i
+find . \-path "./sr*sc"
+.br
+.in -1i
+will print an entry for a directory called `./src/misc' (if one
+exists).  To ignore a whole directory tree, use
+.B \-prune
+rather than
+checking every file in the tree.  For example, to skip the
+directory `src/emacs' and all files and directories under it, and
+print the names of the other files found, do something like this:
+.br
+.in +1i
+find . \-path ./src/emacs \-prune \-o \-print
+.br
+.in -1i
+Note that the pattern match test applies to the whole file name,
+starting from one of the start points named on the command line.  It
+would only make sense to use an absolute path name here if the
+relevant start point is also an absolute path.  This means that this
+command will never match anything:
+.br
+.in +1i
+find bar \-path /foo/bar/myfile \-print
+.br
+.in -1i
+Find compares the
+.B \-path
+argument with the concatenation of a directory name and the base name
+of the file it's examining.  Since the concatenation will never end
+with a slash,
+.B \-path
+arguments ending in a slash will match nothing (except perhaps a start
+point specified on the command line).
+The predicate
+.B \-path
+is also supported by HP-UX
+.B find
+and will be in a forthcoming version of the POSIX standard.
+
+.IP "\-perm \fImode\fR"
+File's permission bits are exactly \fImode\fR (octal or symbolic).
+Since an exact match is required, if you want to use this form for
+symbolic modes, you may have to specify a rather complex mode string.
+For example `\-perm g=w' will only match files which have mode 0020
+(that is, ones for which group write permission is the only permission
+set).  It is more likely that you will want to use the `/' or `-'
+forms, for example `\-perm \-g=w', which matches any file with group
+write permission.  See the
+.B EXAMPLES
+section for some illustrative examples.
+
+.IP "\-perm \-\fImode\fR"
+All of the permission bits \fImode\fR are set for the file.
+Symbolic modes are accepted in this form, and this is usually the way
+in which you would want to use them.  You must specify `u', `g' or `o' if
+you use a symbolic mode.   See the
+.B EXAMPLES
+section for some illustrative examples.
+
+.IP "\-perm /\fImode\fR"
+Any of the permission bits \fImode\fR are set for the file.  Symbolic
+modes are accepted in this form.  You must specify `u', `g' or `o' if
+you use a symbolic mode.  See the
+.B EXAMPLES
+section for some illustrative examples.  If no permission bits in
+.I mode
+are set, this test matches any file (the idea here is to be consistent
+with the behaviour of
+.B \-perm
+.BR \-000 ).
+
+.IP "\-perm +\fImode\fR"
+This is no longer supported (and has been deprecated since 2005).  Use
+.B "\-perm /\fImode\fR"
+instead.
+
+.IP \-readable
+Matches files which are readable.  This takes into account access
+control lists and other permissions artefacts which the
+.B \-perm
+test ignores.  This test makes use of the
+.BR access (2)
+system call, and so can be fooled by NFS servers which do UID
+mapping (or root-squashing), since many systems implement
+.BR access (2)
+in the client's kernel and so cannot make use of the UID mapping
+information held on the server.
+
+.IP "\-regex \fIpattern\fR"
+File name matches regular expression \fIpattern\fR.  This is a match
+on the whole path, not a search.  For example, to match a file named
+`./fubar3', you can use the regular expression `.*bar.' or `.*b.*3',
+but not `f.*r3'.  The regular expressions understood by
+.B find
+are by default Emacs Regular Expressions, but this can be
+changed with the
+.B \-regextype
+option.
+
+.IP "\-samefile \fIname\fR"
+File refers to the same inode as \fIname\fR.   When
+.B \-L
+is in effect, this can include symbolic links.
+
+.IP "\-size \fIn\fR[cwbkMG]"
+File uses \fIn\fP units of space, rounding up.  The following suffixes
+can be used:
+.RS
+.IP `b'
+for 512-byte blocks (this is the default if no suffix is used)
+.IP `c'
+for bytes
+.IP `w'
+for two-byte words
+.IP `k'
+for Kilobytes (units of 1024 bytes)
+.IP `M'
+for Megabytes (units of 1048576 bytes)
+.IP `G'
+for Gigabytes (units of 1073741824 bytes)
+.RE
+.IP
+The size does not count indirect blocks, but it does count blocks in
+sparse files that are not actually allocated.  Bear in mind that the
+`%k' and `%b' format specifiers of
+.B \-printf
+handle sparse files
+differently.  The `b' suffix always denotes 512-byte blocks and never
+1 Kilobyte blocks, which is different to the behaviour of
+.BR \-ls .
+The + and - prefixes signify greater than and less than, as usual,
+but bear in mind that the size is rounded up to the next unit (so a
+1-byte file is not matched by
+.BR "-size -1M" ).

+command, not just in arguments where it is alone, as in some versions
+of
+.BR find .
+Both of these constructions might need to be escaped (with a `\e') or
+quoted to protect them from expansion by the shell.  See the
+.B EXAMPLES
+section for examples of the use of the
+.B \-exec
+option.  The specified
+command is run once for each matched file.
+The command is executed in the starting directory.   There are
+unavoidable security problems surrounding use of the
+.B \-exec
+action;
+you should use the
+.B \-execdir
+option instead.
+
+.IP "\-exec \fIcommand\fR {} +"
+This variant of the
+.B \-exec
+action runs the specified command on the
+selected files, but the command line is built by appending each
+selected file name at the end; the total number of invocations of the
+command will be much less than the number of matched files.  The
+command line is built in much the same way that
+.B xargs
+builds its command lines.  Only one instance of `{}' is allowed within
+the command.  The command is executed in the starting directory.  If
+.B find
+encounters an error, this can sometimes cause an
+immediate exit, so some pending commands may not be run
+at all.  This variant of
+.B \-exec
+always returns true.
+
+.IP "\-execdir \fIcommand\fR ;"
+.IP "\-execdir \fIcommand\fR {} +"
+Like
+.BR \-exec ,
+but the specified command is run from the subdirectory
+containing the matched file, which is not normally the directory in
+which you started
+.BR find .
+This a much more secure method for invoking commands, as it avoids
+race conditions during resolution of the paths to the matched files.
+As with the
+.B \-exec
+action, the `+' form of
+.B \-execdir
+will build a
+command line to process more than one matched file, but any given
+invocation of
+.I command
+will only list files that exist in the same subdirectory.  If you use
+this option, you must ensure that your
+.B $PATH
+environment variable does not reference `.';
+otherwise, an attacker can run any commands they like by leaving an
+appropriately-named file in a directory in which you will run
+.BR \-execdir .
+The same applies to having entries in
+.B $PATH
+which are empty or which are not absolute directory names.  If
+.B find
+encounters an error, this can sometimes cause an
+immediate exit, so some pending commands may not be run
+at all. The result of the action depends on whether the
+.B +
+or the
+.B ;
+variant is being used;
+.B \-execdir
+.I command
+.B {} +
+always returns true, while
+.B \-execdir
+.I command
+.B {} ;
+returns true only if
+.I command
+returns 0.

+does not exist when \fBfind\fR is run, it is created; if it does
+exist, it is truncated.  The file names `/dev/stdout' and
+`/dev/stderr' are handled specially; they refer to the standard

+but ask the user first.  If the user agrees, run the command.  Otherwise
+just return false.  If the command is run, its standard input is redirected
+from
+.BR /dev/null .
+
+.IP
+The response to the prompt is matched against a pair of regular
+expressions to determine if it is an affirmative or negative
+response.  This regular expression is obtained from the system if the
+`POSIXLY_CORRECT' environment variable is set, or otherwise from
+.BR find 's
+message translations.  If the system has no suitable
+definition,
+.BR find 's
+own definition will be used.   In either case, the interpretation of
+the regular expression itself will be affected by the environment
+variables 'LC_CTYPE' (character classes) and 'LC_COLLATE' (character
+ranges and equivalence classes).

+seriously consider using the
+.B \-print0
+option instead of
+.BR \-print .
+See the
+.B UNUSUAL FILENAMES
+section for information about how unusual characters in filenames are handled.
+
+.IP \-print0
+True; print the full file name on the standard output, followed by a
+null character (instead of the newline character that
+.B \-print
+uses).
+This allows file names that contain newlines or other types of white
+space to be correctly interpreted by programs that process the
+\fBfind\fR output.  This option corresponds to the
+.B \-0
+option of
+.BR xargs .
+
+.IP "\-printf \fIformat\fR"
+True; print \fIformat\fR on the standard output, interpreting `\e'
+escapes and `%' directives.  Field widths and precisions can be
+specified as with the `printf' C function.  Please note that many of
+the fields are printed as %s rather than %d, and this may mean that
+flags don't work as you might expect.  This also means that the `\-'
+flag does work (it forces fields to be left-aligned).  Unlike
+.BR \-print ,
+.B \-printf
+does not add a newline at the end of the string.  The escapes

+A `%' character followed by any other character is discarded, but the

+of \fIexpr2\fR.  The comma operator can be useful for searching for
+several different types of thing, but traversing the filesystem
+hierarchy only once.  The
+.B \-fprintf
+action can be used to list the various matched items into several
+different output files.
+
+
+.SH UNUSUAL FILENAMES
+Many of the actions of
+.B find
+result in the printing of data which is under the control of other
+users.  This includes file names, sizes, modification times and so
+forth.  File names are a potential problem since they can contain any
+character except `\e0' and `/'.  Unusual characters in file names can
+do unexpected and often undesirable things to your terminal (for
+example, changing the settings of your function keys on some
+terminals).  Unusual characters are handled differently by various
+actions, as described below.
+
+.IP "\-print0, \-fprint0"
+Always print the exact filename, unchanged, even if the output is
+going to a terminal.
+
+.IP "\-ls, \-fls"
+Unusual characters are always escaped.  White space, backslash, and
+double quote characters are printed using C-style escaping (for
+example `\ef', `\e"').  Other unusual characters are printed using an
+octal escape.  Other printable characters (for
+.B \-ls
+and
+.B \-fls
+these are the characters between octal 041 and 0176) are printed as-is.
+
+.IP "\-printf, \-fprintf"
+If the output is not going to a terminal, it is printed as-is.
+Otherwise, the result depends on which directive is in use.  The
+directives %D, %F, %g, %G, %H, %Y, and %y expand to values which are
+not under control of files' owners, and so are printed as-is.  The
+directives %a, %b, %c, %d, %i, %k, %m, %M, %n, %s, %t, %u and %U have
+values which are under the control of files' owners but which cannot
+be used to send arbitrary data to the terminal, and so these are
+printed as-is.  The directives %f, %h, %l, %p and %P are quoted.  This
+quoting is performed in the same way as for GNU
+.BR ls .
+This is not the same quoting mechanism as the one used for
+.B \-ls
+and
+.BR \-fls .
+If you are able to decide what format to use for the output of
+.B find
+then it is normally better to use `\e0' as a terminator
+than to use newline, as file names can contain white space and newline
+characters.  The setting of the `LC_CTYPE' environment
+variable is used to determine which characters need to be quoted.
+
+.IP "\-print, \-fprint"
+Quoting is handled in the same way as for
+.B \-printf
+and
+.BR \-fprintf .
+If you are using
+.B find
+in a script or in a situation where the matched files might have
+arbitrary names, you should consider using
+.B \-print0
+instead of
+.BR \-print .
+.P
+The
+.B \-ok
+and
+.B \-okdir
+actions print the current filename as-is.  This may change in a future release.
+
+.SH "STANDARDS CONFORMANCE"
+For closest compliance to the POSIX standard, you should set the
+POSIXLY_CORRECT environment variable.  The following options are
+specified in the POSIX standard (IEEE Std 1003.1, 2003 Edition):
+
+.IP \fB\-H\fR
+This option is supported.
+
+.IP \fB\-L\fR
+This option is supported.
+
+.IP \fB\-name\fR
+This option is supported, but POSIX conformance depends on the
+POSIX conformance of the system's
+.BR fnmatch (3)
+library function.  As of findutils-4.2.2, shell metacharacters
+(`*', `?' or `[]' for example) will match a leading `.', because
+IEEE PASC interpretation 126 requires this.   This is a change from
+previous versions of findutils.
+
+.IP \fB\-type\fR
+Supported.   POSIX specifies `b', `c', `d', `l', `p', `f' and `s'.
+GNU find also supports `D', representing a Door, where the OS provides these.
+
+.IP \fB\-ok\fR
+Supported.
+Interpretation of the response is according to the "yes" and "no"
+patterns selected by setting the `LC_MESSAGES' environment variable.
+When the `POSIXLY_CORRECT' environment variable is set, these patterns
+are taken system's definition of a positive (yes) or negative (no)
+response.  See the system's
+documentation for \fBnl_langinfo\fP(3), in particular YESEXPR and
+NOEXPR.    When `POSIXLY_CORRECT' is not set, the patterns are instead
+taken from
+.BR find 's
+own message catalogue.
+
+.IP \fB\-newer\fR
+Supported.  If the file specified is a symbolic link, it is always
+dereferenced.  This is a change from previous behaviour, which used to
+take the relevant time from the symbolic link; see the HISTORY section
+below.
+
+.IP \fB\-perm\fR
+Supported.  If the POSIXLY_CORRECT environment variable is not set,
+some mode arguments (for example +a+x) which are not valid in POSIX
+are supported for backward-compatibility.
+
+.IP "Other predicates"
+The predicates
+.BR \-atime ,
+.BR \-ctime ,
+.BR \-depth ,
+.BR \-group ,
+.BR \-links ,
+.BR \-mtime ,
+.BR \-nogroup ,
+.BR \-nouser ,
+.BR \-print ,
+.BR \-prune ,
+.BR \-size ,
+.BR \-user
+and
+.B \-xdev
+`\-atime',
+`\-ctime',
+`\-depth',
+`\-group',
+`\-links',
+`\-mtime',
+`\-nogroup',
+`\-nouser',
+`\-perm',
+`\-print',
+`\-prune',
+`\-size',
+`\-user' and
+`\-xdev',
+are all supported.
+
+.P
+The POSIX standard specifies parentheses `(', `)', negation `!' and the
+`and' and `or' operators (
+.BR \-a ,
+.BR \-o ).
+.P
+All other options, predicates, expressions and so forth are extensions
+beyond the POSIX standard.  Many of these extensions are not unique to
+GNU find, however.
+.P
+The POSIX standard requires that
+.B find
+detects loops:
+.IP
+The
+.B find
+utility shall detect infinite loops; that is, entering a
+previously visited directory that is an ancestor of the last file
+encountered.  When it detects an infinite loop, find shall write a
+diagnostic message to standard error and shall either recover its
+position in the hierarchy or terminate.
+.P
+GNU
+.B find
+complies with these requirements.  The link count of
+directories which contain entries which are hard links to an ancestor
+will often be lower than they otherwise should be.  This can mean that
+GNU find will sometimes optimise away the visiting of a subdirectory
+which is actually a link to an ancestor.  Since
+.B find
+does not actually enter such a subdirectory, it is allowed to avoid
+emitting a diagnostic message.  Although this behaviour may be
+somewhat confusing, it is unlikely that anybody actually depends on
+this behaviour.  If the leaf optimisation has been turned off with
+.BR \-noleaf ,
+the directory entry will always be examined and the diagnostic message
+will be issued where it is appropriate.  Symbolic links cannot be used
+to create filesystem cycles as such, but if the
+.B \-L
+option or the
+.B \-follow
+option is in use, a diagnostic message is issued when
+.B find
+encounters a loop of symbolic links.  As with loops containing hard
+links, the leaf optimisation will often mean that
+.B find
+knows that it doesn't need to call
+.I stat()
+or
+.I chdir()
+on the symbolic link, so this diagnostic is frequently not necessary.
+.P
+The
+.B \-d
+option is supported for compatibility with various BSD systems,
+but you should use the POSIX-compliant option
+.B \-depth
+instead.
+.P
+The POSIXLY_CORRECT environment variable does not affect the behaviour
+of the
+.B \-regex
+or
+.B \-iregex
+tests because those tests aren't specified in the POSIX standard.
+.SH "ENVIRONMENT VARIABLES"
+
+.IP LANG
+Provides a default value for the internationalization variables that
+are unset or null.
+
+.IP LC_ALL
+If set to a non-empty string value, override the values of all the
+other internationalization variables.
+
+.IP LC_COLLATE
+The POSIX standard specifies that this variable affects the pattern
+matching to be used for the
+.B \-name
+option.   GNU find uses the
+.BR fnmatch (3)
+library function, and so support for `LC_COLLATE' depends on the
+system library.    This variable also affects the interpretation of
+the response to
+.BR \-ok;
+while the `LC_MESSAGES' variable selects the actual pattern used to
+interpret the response to
+.BR \-ok ,
+the interpretation of any bracket expressions in the pattern will be
+affected by `LC_COLLATE'.
+
+.IP LC_CTYPE
+This variable affects the treatment of character classes used in
+regular expressions and also with
+the
+.B \-name
+test, if the system's
+.BR fnmatch (3)
+library function supports this.  This variable also affects the
+interpretation of any character classes in the regular expressions
+used to interpret the response to the prompt issued by
+.BR \-ok .
+The `LC_CTYPE' environment variable will
+also affect which characters are considered to be unprintable when
+filenames are printed; see the section UNUSUAL FILENAMES.
+
+.IP LC_MESSAGES
+Determines the locale to be used for internationalised messages.  If
+the `POSIXLY_CORRECT' environment variable is set, this also
+determines the interpretation of the response to the prompt made by the
+.BR \-ok
+action.
+
+.IP NLSPATH
+Determines the location of the internationalisation message catalogues.
+
+.IP PATH
+Affects the directories which are searched to find the executables
+invoked by
+.BR \-exec ,
+.BR \-execdir ,
+.B \-ok
+and
+.BR \-okdir .
+
+.IP POSIXLY_CORRECT
+Determines the block size used by
+.B \-ls
+and
+.BR \-fls .
+If
+.B POSIXLY_CORRECT
+is set, blocks are units of 512 bytes.  Otherwise they are units of 1024 bytes.
+.IP
+Setting this variable also turns off
+warning messages (that is, implies
+.BR \-nowarn )
+by default, because POSIX requires that apart from
+the output for
+.BR \-ok ,
+all messages printed on stderr are diagnostics and must result in a
+non-zero exit status.
+.IP
+When POSIXLY_CORRECT is not set,
+.B \-perm
++zzz
+is treated just like
+.B \-perm
+/zzz
+if
++zzz is not a valid symbolic mode.  When POSIXLY_CORRECT is set, such
+constructs are treated as an error.
+.IP
+When POSIXLY_CORRECT is set, the response to the prompt made by the
+.B \-ok
+action is interpreted according to the system's message catalogue, as
+opposed to according to
+.BR find 's
+own message translations.
+
+.IP TZ
+Affects the time zone used for some of the time-related format
+directives of
+.B \-printf
+and
+.BR \-fprintf .
+.SH "EXAMPLES"
+.nf
+.B find /tmp \-name core \-type f \-print | xargs /bin/rm \-f
+
+.fi
+Find files named
+.B core
+in or below the directory
+.B /tmp
+and delete them.  Note that this will work incorrectly if there are
+any filenames containing newlines, single or double quotes, or spaces.
+.P
+.B find /tmp \-name core \-type f \-print0 | xargs \-0 /bin/rm \-f
+
+.fi
+Find files named
+.B core
+in or below the directory
+.B /tmp
+and delete them, processing filenames in such a way that file or
+directory names containing single or double quotes, spaces or newlines
+are correctly handled.  The
+.B \-name
+test comes before the
+.B \-type
+test in order to avoid having to call
+.B stat(2)
+on every file.
+
+.P
+.nf
+.B find . \-type f \-exec file \(aq{}\(aq \e;
+
+.fi
+Runs `file' on every file in or below the current directory.  Notice
+that the braces are enclosed in single quote marks to protect them
+from interpretation as shell script punctuation.  The semicolon is
+similarly protected by the use of a backslash, though single quotes
+could have been used in that case also.
+
+.P
+.nf
+.B find / \e( \-perm \-4000 \-fprintf /root/suid.txt \(aq%#m %u %p\en\(aq \e) , \e
+.B  \e( \-size +100M \-fprintf /root/big.txt  \(aq%\-10s %p\en\(aq \e)
+
+.fi
+Traverse the filesystem just once, listing setuid files and
+directories into
+.B /root/suid.txt
+and large files into
+.BR /root/big.txt .
+
+.P
+.nf
+.B find $HOME  \-mtime 0
+
+.fi
+Search for files in your home directory which have been modified in
+the last twenty-four hours.  This command works this way because the
+time since each file was last modified is divided by 24 hours and any
+remainder is discarded.  That means that to match
+.B \-mtime
+.BR 0 ,
+a file will have to have a modification in the past which is less than
+24 hours ago.
+
+.P
+.nf
+.B find /sbin /usr/sbin -executable \e! -readable \-print
+
+.fi
+Search for files which are executable but not readable.
+
+.P
+.nf
+.B find . \-perm 664
+
+.fi
+Search for files which have read and write permission for their owner,
+and group, but which other users can read but not write to.  Files
+which meet these criteria but have other permissions bits set (for
+example if someone can execute the file) will not be matched.
+
+.P
+.nf
+.B find . \-perm \-664
+
+.fi
+Search for files which have read and write permission for their owner
+and group, and which other users can read, without regard to the
+presence of any extra permission bits (for example the executable
+bit).  This will match a file which has mode 0777, for example.
+
+.P
+.nf
+.B find . \-perm /222
+
+.fi
+Search for files which are writable by somebody (their owner, or
+their group, or anybody else).
+
+.P
+.nf
+.B find . \-perm /220
+.B find . \-perm /u+w,g+w
+.B find . \-perm /u=w,g=w
+
+.fi
+All three of these commands do the same thing, but the first one uses
+the octal representation of the file mode, and the other two use the
+symbolic form.  These commands all search for files which are
+writable by either their owner or their group.  The files don't have
+to be writable by both the owner and group to be matched; either will
+do.
+
+.P
+.nf
+.B find . \-perm \-220
+.B find . \-perm \-g+w,u+w
+
+.fi
+Both these commands do the same thing; search for files which are
+writable by both their owner and their group.
+
+.P
+.nf
+.B find . \-perm \-444 \-perm /222 ! \-perm /111
+.B find . \-perm \-a+r \-perm /a+w ! \-perm /a+x
+
+.fi
+These two commands both search for files that are readable for
+everybody (
+.B \-perm \-444
+or
+.BR "\-perm \-a+r" ),
+have at least one write bit
+set (
+.B \-perm /222
+or
+.BR "\-perm /a+w" )
+but are not executable for anybody (
+.B ! \-perm /111
+and
+.B ! \-perm /a+x
+respectively).
+
+.P
+.nf
+.B cd /source-dir
+.B find . \-name .snapshot \-prune \-o \e( \e! \-name "*~" \-print0 \e)|
+.B cpio \-pmd0   /dest-dir
+
+.fi
+This command copies the contents of
+.B /source-dir
+to
+.BR /dest-dir ,
+but omits files and directories named
+.B .snapshot
+(and anything in them).  It also omits files or directories whose name
+ends in
+.BR ~ ,
+but not their contents.  The construct
+.B \-prune \-o \e( \&...\& \-print0 \e)
+is quite common.  The idea here is that the expression before
+.B \-prune
+matches things which are to be pruned.  However, the
+.B \-prune
+action itself returns true, so the following
+.B \-o
+ensures that the right hand side is evaluated only for those
+directories which didn't get pruned (the contents of the pruned
+directories are not even visited, so their contents are irrelevant).
+The expression on the right hand side of the
+.B \-o
+is in parentheses only for clarity.  It emphasises that the
+.B \-print0
+action takes place only for things that didn't have
+.B \-prune
+applied to them.  Because the default `and' condition between tests
+binds more tightly than
+.BR \-o ,
+this is the default anyway, but the parentheses help to show
+what is going on.
+
+.P
+.nf
+.B find repo/ -exec test -d {}/.svn \e; -or \e
+.B -exec test -d {}/.git \e; -or -exec test  -d {}/CVS \e; \e
+.B -print -prune
+.fi
+
+Given the following directory of projects and their associated SCM
+administrative directories, perform an efficient search for the
+projects' roots:
+
+.nf
+.B repo/project1/CVS
+.B repo/gnu/project2/.svn
+.B repo/gnu/project3/.svn
+.B repo/gnu/project3/src/.svn
+.B repo/project4/.git
+
+.fi
+In this example,
+.B \-prune
+prevents unnecessary descent into directories that have already been
+discovered (for example we do not search project3/src because we
+already found project3/.svn), but ensures sibling directories
+(project2 and project3) are found.
+
+.SH EXIT STATUS
+.PP
+.B find
+exits with status 0 if all files are processed successfully, greater
+than 0 if errors occur.   This is deliberately a very broad
+description, but if the return value is non-zero, you should not rely
+on the correctness of the results of
+.BR find .
+
+When some error occurs,
+.B find
+may stop immediately, without completing all the actions specified.
+For example, some starting points may not have been examined or some
+pending program invocations for
+.B \-exec \&...\& {} +
+or
+.B \-execdir \&...\& {} +
+may not have been performed.

+As of findutils-4.2.2, shell metacharacters (`*', `?' or `[]' for

+As of findutils-4.3.3,

+now matches all files instead of none.
+.P
+Nanosecond-resolution
+timestamps were implemented in findutils-4.3.3.
+.P
+As of findutils-4.3.11, the
+.B \-delete
+action sets
+.BR find 's
+exit status to a nonzero value when it fails.
+However,
+.B find
+will not exit immediately.  Previously,
+.BR find 's
+exit status was unaffected by the failure of
+.BR \-delete .

+.P
+The syntax
+\.B \-perm +MODE
+was removed in findutils-4.5.12, in favour of

+The

+syntax had been deprecated since findutils-4.2.21

+.nf
+.B $ find . \-name *.c \-print
+find: paths must precede expression
+Usage: find [\-H] [\-L] [\-P] [\-Olevel] [\-D help|tree|search|stat|rates|opt|exec] [path...] [expression]
+.fi
+.P
+This happens because
+.I *.c
+has been expanded by the shell
+resulting in
+.B find
+actually receiving a command line like this:
+.nf
+
+.B find . \-name bigram.c code.c frcode.c locate.c \-print
+
+.fi
+That command is of course not going to work.  Instead of doing things
+this way, you should enclose the pattern in quotes or escape the wildcard:
+.nf
+.B $ find . \-name \(aq*.c\(aq \-print
+.B $ find . \-name \e*.c \-print
+.fi
+
+.SH "BUGS"
+.P
+There are security problems inherent in the behaviour that the POSIX
+standard specifies for
+.BR find ,
+which therefore cannot be fixed.  For example, the
+.B \-exec
+action is
+inherently insecure, and
+.B \-execdir
+should be used instead.
+Please see \fBFinding Files\fP for more information.
+.P
+The environment variable
+.B  LC_COLLATE
+has no effect on the
+.B \-ok
+action.
+.P
+The best way to report a bug is to use the form at
+http://savannah.gnu.org/bugs/?group=findutils.
+The reason for this is that you will then be able to track progress in
+fixing the problem.   Other comments about \fBfind\fP(1) and about
+the findutils package in general can be sent to the
+.I bug\-findutils
+mailing list.  To join the list, send email to
