List processes that match a string.

README.md

I named this file psg and put it in a place where my PATH could find it. You could do that, too. Also, you'll want it to be executable: chmod +x /path/to/psg.

psg.sh

#!/bin/bash

if [[ -z $1 ]]; then
  echo -e "Usage: psg pattern\n\nShow processes whose name matches the pattern."
else
  pid_list=$(pgrep -d, $1)

  if [[ -n $pid_list ]]; then
    ps up ${pid_list}
  fi
fi
