 This is a helpful way to keep your containers from running out of space. Create a auto-prune cron job and put it in `etc/cron.daily`.
 
 ```bash
-nano /etc/cron.daily/docker-prune
-```
-
-```bash
+cat <<EOF | sudo tee /etc/cron.daily/docker-prune
 #!/bin/bash
 
-UUID=00000000-0000-0000-0000-0000000000
+UUID=00000000-0000-0000-0000-000000000000
+HOST=healthchecks.io
 
-curl -m 5 --retry 5 https://healthchecks.io/ping/${UUID}/start &>/dev/null
+curl -m 5 --retry 5 https://\${HOST}/ping/\${UUID}/start
 docker system prune --volumes -af
-curl -m 5 --retry 5 https://healthchecks.io/ping/${UUID} &>/dev/null
+curl -m 5 --retry 5 https://\${HOST}/ping/\${UUID}
+EOF
+```
+
+```bash
+sudo chmod +x /etc/cron.daily/docker-prune && /etc/cron.daily/docker-prune
 ```
 
 This also includes a ping out to [healthcheck.io](https://healthchecks.io), which is a really handy thing to track your cron jobs. You can also self host the service.
