Hi, please help me create a UNIX module to run and rerun sas programs dependently. If sample1.sas fails will rerun and not continue will sample2.sas and sample3.sas

Look at the conditional operators in UNIX shells:

command1 && command2

means that command2 will only be run if command1 succeeds

command1 && command2 || command3

if command1 succeeds, run command2, else run command3

 

for loop structures in UNIX shells, see https://www.tutorialspoint.com/unix/unix-shell-loops.htm. You'll also find lots of other information for shell scripoting on that website.

I'd use a scheduler like LSF for a production system. Enterprise grade schedulers are built for handling such dependencies.

Thank you for you replies,really helpful. In the UNIX Script. create a loop to test the sas program is fail or success. If Fail sleep for a minute to check error. Script will rerun until success then go to next sas progran.

 

f=sasprogram
for f in saslist
	do
		sas sasdirectory/$f -log /sas_log/$f.$date.log
		until [ $? -eq 0 ];
		do
		  echo "Processing $f: job fail...\n"
		  echo "Please see error details" /sas_log/$f.$date.log
		  sleep 60 *1 minute
		  sas $sas_dir/$f -log $sas_log/$f.$dateparm.log
		done
		"Processing $f: job success...\n" 
	done
exit 0
