The program I am trying to compile is heavily embedded in a csh environment, and that is what I need to use. I normally use bash, but in this case I am stuck with csh. Russ P.

You can even test your script from a nonlogin shell (which will emulate the crontab environment, though not completely). --keith -- kkeller-usenet(a)wombat.san-francisco.ca.us (try just my userid to email me) AOLSFAQ=http://www.therockgarden.ca/aolsfaq.txt see X- headers for PGP signature information

And the compilation is somehow able to depend on csh? This sounds like a disaster-in-waiting to begin with. In any event, try running "env" at a prompt (redirected to a file), then nuke any lines you're sure don't matter, change the rest from FOO=bar to setenv FOO bar and append it to the script in question. That may do it. -s -- Copyright 2010, all wrongs reversed.

What is confusing about that? It seems to me like a rather straightforward thing to do. Here's my situation. I am writing software that needs to communicate through a socket with another large program. The other large program is maintained in ClearCase, and I need to be able to compile it in my ClearCase "view." That takes something like 10 to 20 minutes. So rather than sit and wait for it, I figure I'll just have a cron job do it for me in the middle of the night every night. Now, this large program apparently depends on may environment variables that were set up using csh. We have a "standard" cshrc file that others use, but I use bash myself. I took Keith Keller's suggestion to source .cshrc in the compilation startup script, but that didn't solve my problem. I'm about ready to just say to hell with it and just compile it from the command line. Something is f***ed up -- maybe me. In any case, I certainly appreciate the suggestions that were offered here.

Normally I use crontabs for regular maintenance tasks, like *running* programs, but I build them with a person there to watch the build.

Here's what I'd probably do: #!/bin/sh csh -c 'source /standard/cshrc; cd /path/to/source; make' > I took Keith Keller's suggestion to source .cshrc in the compilation > startup script, but that didn't solve my problem.

Run a cron job to the effect of: env | mail -s "cron environment" $yourname and compare it with running 'env' in an environment where the build succeeds. -s -- Copyright 2010, all wrongs reversed.
