Bash line output?

Question

bash

There is such a line in the bash script
procc nginx
that finds the id of the nginx processes and returns it, but returns it in one list, so you can’t use the same nice (example). You need to somehow take the ID in turn and execute the command for each separately. How to do it?

Answer 1

so get the whole list and process it line by line.

PIDS=`pgrep nginx`
for pid in ${PIDS[@]}; do
  echo "${pid} # поменять строку на команду"
done
