I'm trying to start Firefox from bash and I want it to open the webconsole on start (this can be done by pressing F12 rigth after it started). Is there a bash command that starts the programm and sends the F12 key while starting? I already looked at xdotool and tried to create a bash script, that starts firefox and then sends the key with xdotool, but the xdotool command isn't run until I close firefox.

    Hmm, you could background firefox with firefox & and then kluge in a sleep 7 or something to wait for firefox to spin up. A better solution might be to configure firefox to show the webconsole by default, but that might require an add-on or delving through about:config ? – thrig Sep 13 '15 at 19:59
  • I already searched for methods that start the webconsole, but the only option I found is the -jsconsole option and that starts the browserconsole instead of the webconsole. I haven't found any config options or addons that do this, thats why I'm searching for a way to do it in a bash script. – user134007 Sep 13 '15 at 20:04
set -e #abort if anything fails
firefox & #run firefox in the background
pid=$!    #remember its pid

#Poll X until firefox sets up a window
#remember the X id of the window
while [ -z "$id" ]; do
    id=$(xdotool search --onlyvisible --pid $pid) 
    sleep 0.1 #poll interval

#Bring the window to the front and send it the F12 key
xdotool windowactivate $id && xdotool key F12
disown "$pid"

This isn't very robust, though. Configuring firefox to open the console by itself would be better.

    Is there an urgent call from the NYSE for some risky business? If not then sleep 1 is fully sufficient. – ott-- Sep 13 '15 at 20:37
