This file stores information about the groups on your system.
Each line in /etc/group is in this format:
groupname:x:group_ID:[username[,username]...]
The fields are separated by colons and include:
- groupname
- The name of the group. Like a user's name, this can contain any characters
except a colon (:), but you should probably avoid any of the
shell's special characters. For more information, see
“Quoting special characters” in Using the Command Line.
- x
- The password for the group. QNX Neutrino doesn't support group passwords.
- group_ID
- The numeric group ID.
- username[,username]...
- The user names of the accounts that belong to this group, separated by commas
(,).
Here's a sample entry:
