[lug] Scripting question

[Davide Del Vento]

I suspect the issue is that cron jobs do not get the same enviroment that a
login shell does. You'll probably have to source the /etc/profile or
something like that as first thing in the cron job. You might try

env > env.txt

both in login and in a cron job job and then diff'ing the difference.

Happy Holidays to you too.
