hold my shell without using resources

[squash]

Hello all,

Doug the amateur scripter again.

The setup:
I use a sun workstation to monitor about 80 other Unix boxes ( mostly sun some aix).
After my 12 hour shift I pull my card out of the sun workstation and it retains all my sessions ( way cool).
Next shift I reinsert my card and all 80 sessions come up as I left them, or so I would hope.
Most of my shells have timed out which loses dce connections etc.

Not really that big a deal but hey if I can prevent it great. I have a simple script that I use:

while :
date
sleep 14400
done

But think this may be using system resources.
Does anyone know if this is true, and if so what could I do otherwise?
Setting the TMOUT env is not really an option as I su to root as do others.

I always use the ksh.

As always I thank you for you support
Doug

Doug,

If your while script works I don't see any reason why you shouldn't go for it. Sleep takes very few resources, if your script works without the call to "date" it would use even less resources.

Oh - and I don't think someone who admins 80 boxes is really an amateur..... <smile> Mike

Mike,
Thankx for the note, always like reading your posts.

The reason for the date call is a hold over from other scripts I write to monitor funcitons. Then I have a visual that the script is not hung in some manner. But your right in this instance I probably dont need it as I am home sleeping while this script is running.

And yes I am not an amateur, as with out the ability to script I would sink in this job.

Doug
