- groupmod [ <-g gid [-o]> ] [ <-n group_name> ] group
The groupmod command modifies the system account files to reflect the changes that are specified on the command line. The options which apply to the groupmod command are
- -g gid
- The numerical value of the group's ID. This value must be unique, unless the -o option is used. The value must be non-negative. Values between 0 and 99 are typically reserved for system groups. Any files which the old group ID is the file group ID must have the file group ID changed manually.
- -n group_name
- The name of the group will be changed from group to group_name.
- /etc/group - group information
- /etc/gshadow - secure group information

- This command is normally not on the search path for executables, so you may need to use whereis to find it.
- This command usually requires root access.
- /usr/sbin/groupmod -n newname oldname
- changes the name of the group; file-ownership and group membership are preserved, i.e. users and files belonging to oldname now belong to newname.
