Unix tip: kill -STOP and kill -CONT

1. Gotta love STOP and CONT! I made some simple bash functions to help me out, so I can type something like “stop firefox” at the prompt.

   # "stop" a process stop(){ if [ $# -ne 1 ]; then echo 1>&2 Usage: stop process else PROCESS=$1 echo "Stopping processes with the word ${tGreen}$1${tReset}" ps axw | grep -i $1 | awk -v PROC="$1" '{print $1}' | xargs kill -STOP fi } # "cont"inue a process cont(){ if [ $# -ne 1 ]; then echo 1>&2 Usage: cont process else PROCESS=$1 echo "Continuing processes with the word ${tGreen}$1${tReset}" ps axw | grep -i $1 | awk -v PROC="$1" '{print $1}' | xargs kill -CONT fi }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

   # "stop" a process stop(){   if [ $# -ne 1 ]; then           echo 1>&2 Usage: stop process   else     PROCESS=$1     echo "Stopping processes with the word ${tGreen}$1${tReset}"     ps axw | grep -i $1 | awk -v PROC="$1" '{print $1}' | xargs kill -STOP   fi }   # "cont"inue a process cont(){   if [ $# -ne 1 ]; then           echo 1>&2 Usage: cont process   else     PROCESS=$1     echo "Continuing processes with the word ${tGreen}$1${tReset}"     ps axw | grep -i $1 | awk -v PROC="$1" '{print $1}' | xargs kill -CONT   fi }

2. Made a little bash script to toggle the state of the active window:
   #!/bin/bash
   myid=$(ps $(xdotool getwindowfocus getwindowpid) |tail -n 1 |awk ‘{print $3}’)
   if [[ $myid == “Sl” ]]
   then
   kill -STOP xdotool getwindowfocus getwindowpid
   else
   kill -CONT xdotool getwindowfocus getwindowpid
   fi

3. CTRL-Z => stoppe l’appli
   fg => la reprend en arrière plan
   bg => la ramène au premier plan

   Le kill -stop reste bien utile pour les processus sans console.

4. J ene peux éditer mon précédent commentaire.

   Le bon ordre des choses:

   bg => la reprend en arrière plan
   fg => la ramène au premier plan

5. Bonjour!

   I use ctrl-Z, fg and bg all the time (and their friend “jobs”, and tricks like “bg %2” and “kill %2”). But it’s nice to also be able to stop/continue processes that weren’t started from a console.
