I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This really depends on how the accounts are being stored.

If you are using just the files the command is;  
cat /etc/passwd
cat /etc/group

If you are using nis then the command is;    
ypcat passwd
ypcat group

If you are using nis+ then the command is;  
niscat passwd.org_dir
niscat group.org_dir

Many systems use a combination of storage methods, so a machine may have accounts using both files and nis or nis+.
