NAZWA¶groupmod - modyfikuj definicję grupy systemowej
groupmod [opcje] GRUPA
OPIS¶The groupmod command modifies the definition of the specified GROUP by modifying the appropriate entry in the group database.
OPCJE¶The options which apply to the groupmod command are:
-g, --gid GID
The value of GID must be a non-negative decimal integer. This value must be unique, unless the -o option is used.
Users who use the group as primary group will be updated to keep the group as their primary group.
Any files that have the old group ID and must continue to belong to GROUP, must have their group ID changed manually.
No checks will be performed with regard to the GID_MIN, GID_MAX, SYS_GID_MIN, or SYS_GID_MAX from /etc/login.defs.
-n, --new-name NEW_GROUP
-p, --password PASSWORD
Note: This option is not recommended because the password (or encrypted password) will be visible by users listing the processes.
You should make sure the password respects the system's password policy.
-R, --root CHROOT_DIR
-P, --prefix PREFIX_DIR
CONFIGURATION¶The following configuration variables in /etc/login.defs change the behavior of this tool:
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.
