In a korn shell script, I am running expdp. I have made the script to where it can be reusable so if a later process fails, I can run it again without running the already completed steps. I am running two processes in the background and waiting for both to complete before moving ahead in the script. For example, I am using the below logic to wait. After the expdp process completes, I am using a log function to write a completed message.
while ps | grep "expdp" | grep -v grep do echo expdp is still in the ps output. Must still be running. sleep 5 done WriteLog "Completed exporting client schemas"
If the process does not exists (i.e. reusing the script after fixing any errors which occurred after expdp), how do I set it up to where the writelog occurs only when the expdp process exists. If no process is found from ps then it should not write log again.
