Firejail + Chromium (a handy little script)

I've found an interesting little script. I can't take credit for it, but it is unclear to me who the author is.
I will enclose the original url I have found it on. It will also explain what the script does.
Original website I found it on:
http://blog.jdevelop.com/software/linux/2017/09/09/firejail.html

Code:

#!/bin/bash

PID=`firejail --list | grep chromium | awk -F ':' '{print $1;}'`
ARGS="--force-device-scale-factor=1.8"

if [ 'X'$PID = 'X' ];
then
    firejail chromium $ARGS $*
else
    firejail --join="$PID" chromium $ARGS $*
fi

Maybe it is useful for someone to integrate it into a more elaborate script?

 

I don't see why this script should be necessary. Just execute sudo firecfg and all is well.
