* grep: -r with no args now searches "."Paul Eggert2012-01-021-7/+6
| | | | | | | | | | | | | | | | | | | This is a patch I've been meaning to put in for years. When I added support for "grep -r", I forgot to have "grep -r PAT" search the working directory by default, instead of searching standard input (which makes no sense, even if stdin is a directory). This is not an upward compatible change, since "grep -r PAT <file" will no longer search standard input, but that's OK; nobody should be using "grep -r" that way anyway. * NEWS: Document this. * doc/grep.texi (File and Directory Selection, grep Programs, Usage): Likewise. * src/main.c (usage): Likewise. (grepdir): If DIR is null, search the working directory, but do not prepend "./" to the file names. (main): If recursing and no operands are given, search ".". * tests/Makefile.am (TESTS): Add r-dot. * tests/r-dot: New file.

* doc: correct comment about mmapReuben Thomas2011-05-021-1/+1
| | | | | * doc/grep.texi (Other Options) [--mmap]: This option is now ignored, so using it can have no effect on performance.

* grep: diagnose and exit-2 for bogus REs like [:space:], [:digit:], etc.Jim Meyering2010-09-011-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I make a mistake like this: grep '[:lower:]' ... be it in a script or on the command line, I want to know about it as soon as possible. I don't want grep to print a mere warning that it is interpreting this suspicious and almost guaranteed-wrong regular expression as a set of just 6 bytes. And I certainly don't want grep to silently do the wrong thing, even if that would be officially standards-conforming. It's obvious that I intended [[:lower:]], and I want my error to be diagnosed in a way that is most likely to get my attention. Thus, with this change, grep now prints a diagnostic and exits with status 2 the moment it encounters an offending [:char_class:] construct. This changes the way grep works by default, rather than putting this new behavior on an option. A new option would seldom be used in scripts (not portable), and would probably be used only rarely by those who need it the most. This new functionality provides a valuable safety measure and incurs truly negligible risk. For strict POSIX compliance, set POSIXLY_CORRECT in your environment. That disables this new feature. Revert the changes from commit 2cd3bcea, "grep: add --warnings={always,never,auto}.", and then do the following: * src/dfasearch.c (dfawarn): Call getenv("POSIXLY_CORRECT") here; Remove "warning: " from the diagnostic, now that it's more than a warning, and exit with status 2. * NEWS (New features): Describe the new semantics. * tests/warn-char-classes: Adjust one test to accommodate this change. * doc/grep.texi (Character Classes and Bracket Expressions): Document. (Environment Variables): Cross-reference it. Remove reference to obsolete getopt illegal vs. invalid difference. Thanks to Paul Eggert for suggestions and an initial prod.

| | | | | | | | ...to minimize risk of accidentally modifying the generated file rather than its template. These are tiny, so no risk, but it's a good to be consistent, so generated files are easier to spot. * doc/Makefile.am (egrep.1 fgrep.1): When generating these files, ensure that they too are created read-only.

Update copyright year list. Omit the line-splitting \(co directive so that update-copyright will perform future updates automatically. Egmont Koblinger reported the outdated version string and copyright year list in the man page: http://savannah.gnu.org/bugs/?29390

* build: make doc/Makefile.am cleaner and more robustJim Meyering2010-03-291-9/+4
| | | | | | | | | * doc/Makefile.am (egrep.1 fgrep.1): Generate robustly, i.e., do not redirect directly to $@. Use $(AM_V_GEN). Do not distribute intermediate files like fgrep.man and egrep.man. Likewise, do not use them to generate their %.1 images. Instead, generate the .1 files directly.
* grep: remove --mmapPaolo Bonzini2010-03-221-6/+4
| | | | | | | | | | | | | | | mmap is a bad idea for sequentially accessed file because it will cause a page fault for every read page. Just consider it a failed experiment, and ignore --mmap while accepting it for backwards compatibility. * configure.ac (AC_FUNC_MMAP): Remove. * doc/grep.texi (Other options): Say --mmap is ignored. * src/grep.c (mmap_option): Remove. (long_options): Do not reference it. (bufmapped, initial_bufoffset): Remove. (reset, fillbuf): Remove HAVE_MMAP code. (grepfile): Remove bufmapped reference. (usage): Say --mmap is ignored.
