[TriLUG] Cron doesn't seem to run

[Mike Viscount via TriLUG]

it doesn't execute in the shell you're using - each cron job executes in
it's own process/shell

change your sleep command to something like "touch /tmp/filename" and after
it runs you should see a file /tmp/filename with the time of your cron
command.
or echo something into a file like date ... or run a script that leave some
morsels around for you.
