How do I print the current working directory of another user in linux?

Question

Is there a command line I can issue to see what directory another user is currently working in? This would be like using >pwd but for the other user.

There's a cwd symlink in every process' /proc folder, but as a commoner you wouldn't have any rights to read any other's proc folder - only your own:

[marc@panic home]$ ls -l /proc/$$/cwd
lrwxrwxrwx. 1 marc marc 0 May  5 12:06 /proc/16257/cwd -> /home
                                                          ^^^^^---cwd
[marc@panic home]$
            ^^^^---cwd
