groupmod [flaggor] GRUPP
BESKRIVNING¶
The groupmod command modifies the definition of the specified GROUP by modifying the appropriate entry in the group database.FLAGGOR¶
Flaggorna som gäller för kommandot groupmod är: -g, --gid GIDThe group ID of the given GROUP will be changed to
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 NY_GRUPP
The name of the group will be changed from GROUP
to NEW_GROUP name.
-o, --non-unique
When used with the -g option, allow to change the
group GID to a non-unique value.
-p, --password LÖSENORD
Det krypterade lösenordet, som returneras av
crypt(3).
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
Apply changes in the CHROOT_DIR directory and use
the configuration files from the CHROOT_DIR directory.
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.
