How can i list out all the users in the system via command prompt or terminal ?

Code:

who

some extra characters to make the message long enough

To get a list of currently logged in users, the command is (suprisingly) users.

Code:

users

Hi,i cant see the difference between users and who command.Both only show the users currently logged in.I am looking or a command to show all usernames,groupnames ,etc so that i can check if their might be a username i dont know of on a server.

Thanks for any reply.Cheers

That wasn't your initial question.
A simple way would be "cat /etc/passwd", but that wouldn't take into account authentication made from different database (like NIS, LDAP, etc ...).

(1) cat /etc/passwd is OK for <quote>on a server<UnQuote>
(2) contact your dba

Note that even background processes require a login - may be "anonymous"

What do you mean ?

These databases aren't usually handled by dbas but better by system administrators.

Precisely all processes require a userid/groupid, however, they need not to be defined in /etc/passwd or anywhere.
