What's is the most efficient way to get process id of process by name using c++ code. I know, I can execute ps -a | grep "proces-name" to do it , is there better way to do it.

You say "cleanest" and "better", but you forget to say how to measure or compare solutions. – j6t Mar 11 '22 at 09:15

1@AlanBirtles Here, the problem is to find the pid from the name, not the inverse! – Damien Mar 11 '22 at 09:21

I have used `top -b -n1` for a long time, but I don't know if it is *better*. Using `pgrep`in an option too. – Damien Mar 11 '22 at 09:26
