.SH "SYNOPSIS"
|
|
.HP \w'\fBgroupdel\fR\ 'u
|
|
\fBgroupdel\fR [\fIoptions\fR] \fIGROUP\fR
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
The
|
|
\fBgroupdel\fR
|
|
command modifies the system account files, deleting all entries that refer to
|
|
\fIGROUP\fR\&. The named group must exist\&.
|
|
.SH "OPTIONS"
|
|
.PP
|
|
The options which apply to the
|
|
\fBgroupdel\fR
|
|
command are:
|
|
.PP
|
|
\fB\-f\fR, \fB\-\-force\fR
|
|
.RS 4
|
|
This option forces the removal of the group, even if there\*(Aqs some user having the group as the primary one\&.
|
|
.RE
|
|
.PP
|
|
\fB\-h\fR, \fB\-\-help\fR
|
|
.RS 4
|
|
Display help message and exit\&.
|
|
.RE
|
|
.PP
|
|
\fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR
|
|
.RS 4
|
|
Apply changes in the
|
|
\fICHROOT_DIR\fR
|
|
directory and use the configuration files from the
|
|
\fICHROOT_DIR\fR
|
|
directory\&. Only absolute paths are supported\&.
|
|
.RE
|
|
.PP
|
|
\fB\-P\fR, \fB\-\-prefix\fR\ \&\fIPREFIX_DIR\fR
|
|
.RS 4
|
|
Apply changes in the
|
|
\fIPREFIX_DIR\fR
|
|
directory and use the configuration files from the
|
|
\fIPREFIX_DIR\fR
|
|
directory\&. This option does not chroot and is intended for preparing a cross\-compilation target\&. Some limitations: NIS and LDAP users/groups are not verified\&. PAM authentication is using the host files\&. No SELINUX support\&.
|
|
.RE
|
|
.SH "CAVEATS"
|
|
.PP
|
|
You may not remove the primary group of any existing user\&. You must remove the user before you remove the group\&.
|
|
.PP
|
|
You should manually check all file systems to ensure that no files remain owned by this group\&.
|
|
.SH "CONFIGURATION"
|
|
.PP
|
|
The following configuration variables in
|
|
/etc/login\&.defs
|
|
change the behavior of this tool:
|
|
.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\&.
