Off the top of my head I can't think of anything better than system
calls, and my books are at work, but you could simply use another system
command:
$who = `whoami`;
$finger = `finger $who`;
now, if that account has multiple logins, or multiple users using the
same account (tsk on them) you will just have to do more parsing.
check out the man pages. I would think that using `finger -sm $who` is
your best bet with system calls.
