groupdel — stdin stdout - file -- opt --help --version
deletes an existing group.
# groupdel friends
Before doing this, it’s a good idea to identify all files that have their group ID set to the given group, so you can deal with them later:
# find / -group friends -print
groupdel does not
change the group ownership of any files. It simply removes the group
name from the system’s records. If you list such files, you’ll see a
numeric group ID in place of a group name.
