Running a script with systemd on shutdown or reboot
Clash Royale CLAN TAG#URR8PPP
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;
I've made a script which just empties a folder from its contents and then shutdown the pc.
I was wondering if there is a simpler way of doing that automatically when I shutdown or reboot the pc instead of calling the script from the command line. While searching, I found that I probably want a systemd service, but I don't know how to write one and I couldn't find any tutorials on the internet.
After all I just want to run simple single command
rm -rf /my/folder/*
Am I looking the right way, or is there a simpler way to accomplish this?
I want the folder to empty before shutdown and not after the next boot.

This sounds like you are manually creating and managing a temporary directory. If that's the case, check the systemd docs for how it can help with this. See man tmpfiles.d for details.

Set up a cron table entry with a schedule of @reboot to remove and/or recreate the directories in question.

It runs at system startup, since shutdown kills thecrondaemon, it cannot tell the kernel "okey dokey, let me just start one new job.."

On Centos/RHEL 7 there still is a /etc/rc.d/rc.local which uses systemd. I suspect that the same is true on other Linux distributions. This will run the rc.local scripting at reboot. There is significant commenting and warnings in the file that you should really use the systemd type of run structure.
