Check if script is still running in bash
Hi Friends,
Have a script which invoke same shell script with different argument in background (usually runs couple of hours)
In above scenarios,
1. would like to check if all the above script execution has finished or not
2. In a loop with sleep/interval?
3. Once all finished, call a function and exit
I dont want to use sleep which increases the overall time for some reason in the script. Instead would like to use grep and check in a loop. pls help what is the best way to achieve this
e.g
ps -ef | grep backgroundDummyProc | grep -v grep
if [ $? -eq 1 ]
then
echo "Not running"
else
echo "running"
fi
Thanks in advance

Do you want those scripts to run in the background? Run them sequentially and the calling script will wait until the other completes before proceeding.
Without sleep, use a counter I.e. A for loop counting till 10000 between the ps check.
While
Ps
Check status, break out of loop if condition met
For counter
Done
