I want to display:

You can display with the help of compgen builtin command as follows:

However you can also display all users by cut -d ":" -f 1 /etc/passwd.

Nice! it might be preferable to use `getent passwd` / `getent group` instead of cat'ing the local files (`getent` should work for non-local accounts as well) – steeldriver Aug 23 '14 at 14:31
@steeldriver `compgen` does seem to work for non-local accounts (at least for LDAP). – muru Aug 23 '14 at 14:32

@muru I was referring to the second method specifically (`cat /etc/passwd | cut -d ...`) – steeldriver Aug 23 '14 at 14:46
@steeldriver Ah, sorry. I thought that was a more general observation. – muru Aug 23 '14 at 14:57
Well, on my ubuntu, I have some files created by docker mount with `999:999` as `user:group`, but unfortunately none of the above commands prints them. – Marinos An Mar 19 '19 at 11:31

Here we are going to use getent for the detailed the info

We can list the user with the following command:

getent passwd

We can list the group as follows:

getent group

To fetch detail a specific user

getent passwd lalit

Replace the lalit with your user name. Lalit will not be in every system :)
