- -n group_name
- The name of the group will be changed from group to group_name.
Files
- /etc/group - group information
- /etc/gshadow - secure group information

Notes
- 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.
Examples
- /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.
