NAMN
       groupmod - ändra en gruppdefinition på systemet


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 gäller för kommandot groupmod är:

       -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 hjälpmeddelande 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, --passwordLÖSENORD
           The encrypted password, as returned by crypt(3). The default is to
           disable the password.


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.
