I am running a process process_a in loop . I want to get top -H logs stored for all process_a running in loop.
top -b -H -p `pgrep -d, -f process_a`
the above command gave logs for process_a for first loop only
is there a way to get to get top logs for upcoming loops as well ?
This script will repeat forever. I added the -n 1 option. This allows you to rerun the pgrep for each iteration. Note: I used init for the name of the process. Change that to process_a for yours.
#!/bin/sh
while [ true ]; do
top -b -H -n 1 -p `pgrep -d, -f init`
sleep 1
done
