nice &nohup csh functions
2007-12-25 9:39:00
Original problem:
To easyly manages background jobs on a set of workstations I have
modified the /etc/crond.d/* files like at.deny, at.allow and queuedefs.
With the queuedefs file I can restrict the number of background jobs and their
priority for not overloading the machine when a user is sitting in front of
for editing and so on.
But many of my users uses csh for their logging shells, and use nohup and/or
nice csh built-in function to send jobs in background.
Perhaps a silly question :
How can I disable nohup and nice csh built-in command ?
(modify the source code ? )

One reponse and many thanks from: Jochen Bern <bern@TI.Uni-Trier.DE>
There are no trivial solution for this problem, but even if "nohup-csh" is
removed, /usr/bin/nohup still exits ..
Deleting /usr/bin/nohup ? .... "trap sh" built-in remains...
(IN fact /bin/nohup is a /bin/sh script which uses trap ...).
Soft solution. Explain the policy to all users and by a big gun ...
Thanks
