[Techtalk] Script to determine if logged in

[Gutz, Lorne]

If you just want to test to see if a spicific user
is logged in you can use  

  who | grep dan

this will only give you an output when dan is logged in.
This is something that can be easily tested for.

Have a great day
Lorne

Subject: [Techtalk] Script to determine if logged in


I'm trying to write a cron job to determine if I'm logged in. There are
several kludges that I could use, but does anyone know of a good way?

As a variant, is there a good way to determine if ANYONE is logged in,
or logged into X Windows?

Such a script is possible but not easy to test, because part of testing
it requires, er, running the program without being logged in.
