I'm running Ubuntu 18.04.1 and I'm trying to create a script that shuts down Chromium properly before shutting down the system so that it doesn't give me "restore session" popup after booting. I figured I'll use killall to this and came up with
/home/shutdownscript.sh:

#!/bin/bash 
killall -HUP "chromium-browser --enable-pinch"

that seems to do the trick.

However, now I have a problem with actually running this script at shutdown or reboot.

First thing I tried was putting it in /etc/init.d as shutdownscript with chmod +x and then symlinking it to rc0.d and rc6.d as K99shutdownscript and later K01ashutdownscript. However, that didn't work for me.

I thought maybe I should just create a new systemd service, so I created shutdownscript.service in /etc/systemd/system with contents like this:

[Unit]
Description=Saves Chromium session

[Service]
Type=oneshot
RemainAfterExit=true
ExecStart=/bin/true
ExecStop=/home/istir/shutdownscript.sh

[Install]
WantedBy=multi-user.target

Then I ran systemctl start shutdownscript.service and systemctl enable shutdownscript.service but it still didn't work as intended.

The solution is probably very simple but I returned to Linux after around 6 years of using Windows and macOS so I don't really remember what did I do earlier to make shutdown scripts.

Thanks for any help!

With reference to this, we might need to run the following after configuring systemctl.

 sudo systemctl daemon-reload

And we should have a header in the script like below.

### BEGIN INIT INFO
# Provides: scriptname
# Required-Start: 
# Required-Stop: 
# Default-Start: 0 1 6
# Default-Stop: 
# Short-Description: Start daemon at boot time
# Description: Enable service provided by daemon.
### END INIT INFO
