Basics

A service can consist of two files - the .sh script to run, and the .service file which describes its run conditions.

The .service file goes in /etc/systemd/system. The scripts themselves might be best placed in $HOME/.local/bin.

Example - tracker.service

[Unit]
Description=Tracker

[Service]
Type=simple
ExecStart=/path/to/script

[Install]
WantedBy=multi-user.target

After making the new service, systemd requires reloading:

sudo systemctl daemon-reload

Types

• simple - the service cannot be called on by others. It runs on repeat.

• oneshot - the service executes once, then stops.
