# 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
|
|
|
|
|
|
|
|
|
|
```
|
|

[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.
