Hi

I have created user abc123 with primary group "users" and secondary group "work".but user abc123 is not showing in group "user" in the in /etc/group file.

i have given commands like below

$more /etc/passwd|grep abc123
abc123:*:21344:20:testuser:/home/test:/usr/bin/ksh

$more /etc/group |grep users
users::20:root,arcade

but if i check with id commannd its displaying the groupname for abc123
$id -ng abc123
users

$id -nG abc123
work

In the /etc/group file, a user does not need to be added to its primary group. The connection is established in /etc/passwd only. So, if my primary group is 'users' and secondary, 'work' I will only see the username appended to work in the /etc/group file.

I believe this was done to limit the length of lines in /etc/group quite some time ago. However, it is nothing to worry about and the system is behaving as expected.
