description
The
groupdel command modifies the system account files,
deleting all entries that refer to GROUP. The named
group must exist.
options
The options
which apply to the groupdel command are:
-h,
--help
Display help message and
exit.
-R,
--root CHROOT_DIR
Apply changes in the
CHROOT_DIR directory and use the configuration files
from the CHROOT_DIR directory.
caveats
You may not remove the primary group of any existing user. You
must remove the user before you remove the group.
You should manually check all file systems to ensure that no
files remain owned by this group.
configuration
The following configuration variables in /etc/login.defs change
the behavior of this tool:
MAX_MEMBERS_PER_GROUP (number)
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).
The default value is 0, meaning that there are no limits in the
number of members in a group.
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.
If you need to enforce such limit, you can use 25.
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.
exit values
The groupdel command exits with the following values:
0
success
2
invalid command syntax
6
specified group doesn't exist
8
can't remove user's primary group
10
can't update group file
files
/etc/group
Group account information.
/etc/gshadow
Secure group account information.
