How to close epiphany through a script with cron?

I have been making scripts to open and close a specific website with a cronjob on the raspberry Pi. The opening script works perfectly. It is as follows: #!/bin/bash export DISPLAY=:0 && epiphany-browser http://mywebsite sleep 30 xte "key F11" -x:0 xte "key F5" -x:0 But the one to close the browser doesn't work at all, and I can't figure out why. Is there something wrong with the script? I made it by looking at this SuperUser question . #!/bin/bash WID = xdotool search "epiphany-browser" | head-1 xdotool windowactivate --sync $WID xdotool key --clearmodifiers ctrl+q Note: Couldn't get this code to work but the "killall" command works just fine.
