Command Line in Crontab

I have a DataStage server set up on an AIX machine, and when I schedule a job, I typically get something such as the following in the crontab:

/u009/etl/Ascential/DataStage/Projects/Eclipse/dsr_sched.sh /u009/etl/Ascential/DataStage/Projects/Eclipse /u009/etl/Ascential/DataStage/DSEngine ImportRejects 0/0/1/0/0 1 >/dev/null 2>&1 #DSjobDS DSJ.Eclipse.55.1

Now my UNIX admin wants an explanation of each of these parameters and he's particularly interested in the re-directs. I looked in the dsr_sched.sh file and followed some of the logic there but it didn't shed much light. Can anybody explain this command line to me?

Thanks

I'm sorry, but if your UNIX admin doesn't understand what those two redirects are doing - you may need a new admin.

Suggest you take a peek at the dsr_sched.sh script it mentions, that should shed some light on what's going on.

... or you could just wait for Ray to tell you.

If your UNIX admin doesn't understand what those two redirects are doing - you may need a new admin or to demand to see your admin's certification!
