20050221: ipcs and ipcrm problem?

Doug,

The first error message you have:

[GEMPLT -101]  NOPROC - Nonexistent executable

means that either you haven't sourced the $NAWIPS/Gemenviron
variables into your shell script environment, or you have
a file in your working directory with the name of a GEMPAK executable
program such as "gplt" or "ps". It seems that $GEMEXE variable is probably 
not set, which will be set after sucessfully sourcing Gemenviron. When you 
run a script interactively, the script will inherit your environment, but 
when run from a cron or batch mode, you will have to ensure that the shell 
sets its environment since it won't be inheriting your logged in environment.

The error message:
   Error in message send = 22
   itype, ichan, nwords,0,65536,3

signals that you do have a message queue problem, which
is likely due to the program not being able to talk to $GEMEXE/gplt
or $GEMEXE/ps due to the above problem.

To clear this up, exit out of GEMPAK and run "cleanup -c".
This command will remove existing message queues (eg, the "ipcrm" command
is run to remove message queues found with "ipcs"). It will also
look for running "gplt" processes and kill them. 

After running the cleanup command, use the /bin/ps command in linux
to see if you have any gempak device drivers still running (eg xw, gf, ps).
After clearing the environment, make sure your script is sourcing Gemenviron,
and then retry.

Lastly, you can clean up your DEVICE line in you script to
remove the space between the "ps" and "|" characters which 
shouldn't be a problem (unless its some control character I can't
see in the text file dump.
