Explanations for "gs"

Raynald Boucher — Thu, 12 Jul 2007 11:55:22 GMT

Hello all,
We just ran into a b.. of a problem where a command works successfully when the script containing it is run from the command line but fails when started by Autosys on a remote server. The command is:

exec gs $OPTIONS -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite "-sOutputFile=$outfile"
$OPTIONS -c .setpdfwrite -f "$infile"

Can anyone explain this command, specifically the "-c .setpdferite" options.
$OPTIONS contains "-dSAFER -dCompatibilityLevel=1.2"

And where can I find which shared libraries gs is referencing?

Thanks

To see the shared libraries simply run;

ldd gs

You will need to be in the correct directory or use the full path.

What error(s) are you getting when running from Autosys? The main problem I've seen is with the environment settings. When logged into the server and running via command line you may have the correct environment, but unless defined correctly these may not work from Autosys.

It looks like you're using GhostScript to convert a file to PDF. BATCH and NOPAUSE mean don't wait for a user to hit enter and just exit as soon as the whole thing is processed. I think "-c .setpdfwrite" is actually a GhostScript shortcut/macro to set a number of options to the values usually needed for PDF output. GhostScript is kind of complicated, it has way too many options to remember, but the documentation is freely available online.

I'm not on an HP right now, but think you can run chatr or ldd on the binary to list the shared libraries.

We determined that the invalid environment variable was TMPDIR.
We created a workaround by forcibly setting ot in a local profile script.

Does anyone know what the profile setup order is for a job scheduled remotely by autosys to be executed on a Linux server?

Thanks
