SYNOPSIS
       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 galler for kommandot groupmod ar:

       -g, --gidGID
           The 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. Values between 0 and
           999 are typically reserved for system groups.

           Any files that have the old group ID and must continue to belong to
           GROUP, must have their group ID changed manually.

       -h, --help
           Visa hjalpmeddelande och avsluta.

       -n, --new-nameNY_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, --passwordL"OSENORD
           Det krypterade losenordet, 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 systems password
           policy.


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.
