Re: How to check if a user already login?

Hi

Todd's solution is working, to check from the ~/.cvspass.

To summary, when a user has not logged on to cvs:
$ grep "$CVSROOT" ~/.cvspass |awk '{print $3}'
$

After a user logged on to cvs:
$ grep "$CVSROOT" ~/.cvspass |awk '{print $3}'
A,>d^?=I"1
$


Thank everyone!
