Set xtrace/verbose, run your script and post the output:
Code:
#/bin/your_shell -xv

Replace your_shell with ksh, bash whatever that your are using.

The variables in cmd are

Code:
LogFile=LOADS_DIR/devl/logs/LOAD_$(date +%Y%m%d_%H:%M:%S).log
configfile=LOADS_DIR/devl/scripts/SASV9.CFG
autoexecfile=LOADS_DIR/devl/bin/LOAD_autoexec.sas
SourceDir=LOADS_DIR/devl/bin
Program=/usr/local/SAS/SASFoundation/9.2/sas

We are running a SAS job whose input table name changes every time so to solve this we are exporting this as a UNIX variable and inside the SAS job convert again to a SAS variable .
This works fine if the list contains only one variable.

Thanks

You are not using $filelist in your cmd definition, so - if at all - that one identical command is executed twice. And, $filelist will hold one single file name per loop, so the name may be misleading. Why don't you deploy Yoda's advice and post the output of your script executed with xtrace/verbose options?

It is working now, forgot to add the exec command with in the do loop.
Code:
eval $(exec $cmd $*)

Thanks everybody for your valuable inputs...

What is wrong with running it just as $cmd - there's nothing to evaluate, and $Program (sas) is already executable. And why store the command ($cmd) in a variable at all?
