I've got this zsh script. Is there a more a graceful way to do this?

export PROCESSES_TO_QUIT='puma rake sidekiq spring rails ruby-debug phantomjs zeus passenger guard resque "node server.js"'

pgr() {
  echo "Finding processes in list: $PROCESSES_TO_QUIT"  
  for x in `echo ${PROCESSES_TO_QUIT}`; do 
    pgrep -fl $x;

pgk() {
  echo "Killing processes in list: $PROCESSES_TO_QUIT"  
  for x in `echo ${PROCESSES_TO_QUIT}`; do 
    pkill -fl $x;

pgkk() {
  echo "Killing -9 processes in list: $PROCESSES_TO_QUIT"  
  for x in `echo ${PROCESSES_TO_QUIT}`; do 
    pkill -9 -fl $x;

You can use xargs to separate them and execute killall for each one :

echo $PROCESSES_TO_QUIT | xargs killall -9

Maybe try killall:

% export PROCESSES_TO_QUIT='puma rake ...'
% export KILL_SIGNAL='killall -9 '

  • @G-Man, the edits you made do not work for zsh on my system: e.g., processname1, processname2: no process found. Let (AT)justingordon to evaluate the suggestion in this form. – user1717828 May 3 '15 at 13:58
  • Why killall and not pkill? I'm not sure that my list would match the process names automatically. Might, but might not. – justingordon May 3 '15 at 16:24
  • I'm pretty sure killall is just pkill+grep combined. Different strokes for different folks, but with the right options they get the same things done. – user1717828 May 3 '15 at 19:15
