.RE
.PP
\fB\-d\fR, \fB\-\-home\fR\ \&\fIHOME_DIR\fR
.RS 4
The user\*(Aqs new login directory\&.
.sp
If the
\fB\-m\fR
option is given, the contents of the current home directory will be moved to the new home directory, which is created if it does not already exist\&.
.RE
.PP
\fB\-e\fR, \fB\-\-expiredate\fR\ \&\fIDATA_WAŻN\fR
.RS 4
Data, od kt\('orej konto danego użytkownika zostanie wy\(/lączone\&. Data podawana jest w formacie
\fIMM/DD/RR\fR\&.
.sp
An empty
\fIEXPIRE_DATE\fR
argument will disable the expiration of the account\&.
.sp
This option requires a
/etc/shadow
file\&. A
/etc/shadow
entry will be created if there were none\&.
.RE
.PP
\fB\-f\fR, \fB\-\-inactive\fR\ \&\fINIEAKTYWNE\fR
.RS 4
The number of days after a password expires until the account is permanently disabled\&.
.sp
A value of 0 disables the account as soon as the password has expired, and a value of \-1 disables the feature\&.
.sp
This option requires a
/etc/shadow
file\&. A
/etc/shadow
entry will be created if there were none\&.
.RE
.PP
\fB\-g\fR, \fB\-\-gid\fR\ \&\fIGRUPA\fR
.RS 4

.RS 4
A list of supplementary groups which the user is also a member of\&. Each group is separated from the next by a comma, with no intervening whitespace\&. The groups are subject to the same restrictions as the group given with the
\fB\-g\fR
option\&.
.sp
If the user is currently a member of a group which is not listed, the user will be removed from the group\&. This behaviour can be changed via the
\fB\-a\fR
option, which appends the user to the current supplementary group list\&.
.RE
.PP

.RS 4
The name of the user will be changed from
\fILOGIN\fR

.RS 4
Remove a range of subordinate uids from the user\*(Aqs account\&.
.sp
This option may be specified multiple times to remove multiple ranges to a users account\&. When both
\fB\-\-del\-sub\-uids\fR
and
\fB\-\-add\-sub\-uids\fR
are specified, the removal of all subordinate uid ranges happens before any subordinate uid range is added\&.
.sp
No checks will be performed with regard to

.RS 4

.sp
A blank
\fISEUSER\fR
will remove the SELinux user mapping for user
\fILOGIN\fR
(if any)\&.
.RE
.SH "OSTRZEŻENIA"
.PP
You must make certain that the named user is not executing any processes when this command is being executed if the user\*(Aqs numerical user ID, the user\*(Aqs name, or the user\*(Aqs home directory is being changed\&.
\fBusermod\fR
checks this on Linux, but only check if the user is logged in according to utmp on other architectures\&.
.PP
You must change the owner of any
\fBcrontab\fR
files or
\fBat\fR
jobs manually\&.
.PP
You must make any changes involving NIS on the NIS server\&.
.SH "CONFIGURATION"
.PP
The following configuration variables in
/etc/login\&.defs
change the behavior of this tool:
.PP
\fBMAIL_DIR\fR (string)
.RS 4
The mail spool directory\&. This is needed to manipulate the mailbox when its corresponding user account is modified or deleted\&. If not specified, a compile\-time default is used\&.
.RE
.PP
\fBMAIL_FILE\fR (string)
.RS 4
Defines the location of the users mail spool files relatively to their home directory\&.
.RE
.PP
The
\fBMAIL_DIR\fR
and
\fBMAIL_FILE\fR
variables are used by
\fBuseradd\fR,
\fBusermod\fR, and
\fBuserdel\fR
to create, move, or delete the user\*(Aqs mail spool\&.
.PP
If
\fBMAIL_CHECK_ENAB\fR
is set to
\fIyes\fR, they are also used to define the
\fBMAIL\fR
environment variable\&.
.PP
\fBMAX_MEMBERS_PER_GROUP\fR (number)
.RS 4
Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
/etc/group
(with the same name, same password, and same GID)\&.
.sp
The default value is 0, meaning that there are no limits in the number of members in a group\&.
.sp
This feature (split group) permits to limit the length of lines in the group file\&. This is useful to make sure that lines for NIS groups are not larger than 1024 characters\&.
.sp
If you need to enforce such limit, you can use 25\&.
.sp
Note: split groups may not be supported by all tools (even in the Shadow toolsuite)\&. You should not use this variable unless you really need it\&.
.RE
.PP
\fBSUB_GID_MIN\fR (number), \fBSUB_GID_MAX\fR (number), \fBSUB_GID_COUNT\fR (number)
.RS 4
If
/etc/subuid
exists, the commands
\fBuseradd\fR
and
\fBnewusers\fR
(unless the user already have subordinate group IDs) allocate
\fBSUB_GID_COUNT\fR
unused group IDs from the range
\fBSUB_GID_MIN\fR
to
\fBSUB_GID_MAX\fR
for each new user\&.
.sp
The default values for
\fBSUB_GID_MIN\fR,
\fBSUB_GID_MAX\fR,
\fBSUB_GID_COUNT\fR
are respectively 100000, 600100000 and 10000\&.
.RE
.PP
\fBSUB_UID_MIN\fR (number), \fBSUB_UID_MAX\fR (number), \fBSUB_UID_COUNT\fR (number)
.RS 4
If
/etc/subuid
exists, the commands
\fBuseradd\fR
and
\fBnewusers\fR
(unless the user already have subordinate user IDs) allocate
\fBSUB_UID_COUNT\fR
unused user IDs from the range
\fBSUB_UID_MIN\fR
to
\fBSUB_UID_MAX\fR
for each new user\&.
.sp
The default values for
\fBSUB_UID_MIN\fR,
\fBSUB_UID_MAX\fR,
\fBSUB_UID_COUNT\fR
are respectively 100000, 600100000 and 10000\&.
