Systemd Scripts

Systemd can be used to run scripts as services. This is useful for running scripts that need to be run periodically, or that need to be run on a schedule.

Here is an example of how to create a script that will run a script every 5 minutes.

Create a new file called 5min.sh in your home directory.

#!/bin/bash

while true
do
// some work goes here
sleep 5m
done

Make the file executable
```
chmod +x 5min.sh
```

Create a systemd service file

sudo nano /lib/systemd/system/shellscript.service 

Add the following to the file:

[Unit]
Description=Every 5 minutes

[Service]
ExecStart=~/5min.sh

[Install]
WantedBy=multi-user.target

Reload systemd
```
systemctl daemon-reload
```
Start the service
```
systemctl start 5min.service
```
Verify the service is running
```
systemctl status 5min.service
```
Stop the service
```
systemctl stop 5min.service
```
Enable to start on boot
```
systemctl enable 5min.service
```
Check to see if the service is enabled
```
systemctl is-enabled 5min.service
```
Start the service
```
systemctl start 5min.service
```

Note: If you want to disable the service from starting on boot, use systemctl disable 5min.service
