Hi,

I'd like background processes I start to continue running after I
logout but they keep dying. I'm trying to run the following make
script (called MyScript) and then logout:

#!/bin/tcsh -x
setenv OBJECT_MODE 64
cd ~/MainDir
make CC=xlC_r EXTRA_FLAGS="-O3 -qarch=pwr4 -qtune=pwr4 -qipa=level=2
-qstrict -q64 -qwarn64" >& SMO3

So I type MyScript & and it starts running in the background (it is
continually spawning new compile and make threads as it compiles
different files and calls other programs for optimization). When I
logout and then immediately log back in, the make processes have died.
The make process with this level of optimization will take many
hours, so I'd like to be able to logout. Anybody know what I'm doing
wrong?

I'm on AIX 5.1 in tcsh

Thanks,

Steve Rose

I had a similar experience.
It happened when i started a background job run under ksh.
When I start the background job from csh, it continues to run even after logging out.
I have no idea why it works this way.

Try using nohup:
# nohup MyScript &

Regards,

man nohup

or start csh which automatically nohups. (iirc)

Thanks guys - as you suggested, using csh works fine. I guess there's
something about tcsh also.
