The history command: See other users command history

Can anyone tell this:

If two users are logged into the same server from different locations. Is there a way to see the history command of the other user? I tried the history command, but it is showing me only the commands I used.

Thanks in advance for your help.

By default there is no way ulness you have read access to thier sh_history under thier home directories or you have access to root then you can su with thier IDs and see thier histories.
