How can I retrieve the process numbers of a issued multithread application? I mean, I am looking for a bash script that after executing a command, puts the process numbers in a list. For example:
./run_program -nt 4
# find the list of PIDs
I would use
pgrep for checking the process ids.
If you're only looking at child PID of the current process, you can use the
pgrep -P $$
