How to find untracked files in a Perforce tree? (analogue of svn status)

Question

Anybody have a script or alias to find untracked (really: unadded) files in a Perforce tree?

EDIT: I updated the accepted answer on this one since it looks like P4V

Answer 1

The following commands produce status-like output, but none is quite equivalent to svn status or git status, providing a one-line summary of the status of each file:

• p4 status
• p4 opened
• p4 diff -ds
