I first listed the groups using :

groups

I added group using

groupadd -g 300 oinstall

groupadd –g 500 dba

and then when I do

groups 

root bin daemon sys adm disk wheel sfcb

I am unable to find groups I added. How to list groups with group id?
Also, if I try to add it again it says groups is already present.

The groups command lists groups that the user is currently a member of, not all the groups available on the system. You can lookup a group by name or gid using the getent command.

getent group oinstall

getent group 500

To show all the groups, just leave your search query off of the command:

getent group

@Kitex because you created the group but you are not a member of it. You need to add your user to the group then logout and log back in for it to show up with the groups command.

@kinkajou lots of professional experience as well as a lot of time spent on sites such as this one and IRC Linux support. I have been a professional and an enthusiast for about 8 years. I think being an enthusiast is an important part because you are more likely to remember things that you care about.

@kinkajou I used Gnu/Linux for all of my computing at home. Desktops, laptops, raspberry-pi's. I have been using it since 1991 (originally Gnu on Solaris, Dec, HP). I keep adding to my knowledge; No need to through it away, and start again (as with Microsoft's Windows).

You can list groups by using getent

When running the command, the GID is the third value in the output, e.g:

$ getent group

man:x:15:

audio:x:63:

nobody:x:99:

users:x:100:

<--snipped-->

utmp:x:22:

So to only list groupnames and their GID, use awk to print the columns you want like this:

$ getent group | awk -F ":" '{ print $1,$3 }'

man 15

audio 63

nobody 99

users 100

utmp 22

You can list groups by using getent

$ getent group

man:x:15:

nobody:x:99:

utmp:x:22:

So to only list groupnames and their GID, use awk to print the columns you want like this:

$ getent group | awk -F ":" '{ print $1,$3 }'

man 15

audio 63

nobody 99

users 100
