+Automated Bash installer script for configuring **journal log cleanup** on Ubuntu 24.04 Server.

+This script automatically cleans up **journalctl** once a week, retaining logs for **3 days**.

+
+```
+git clone https://git.x-files.dk/server/journal-log-ubuntu.git
+```

+```
+
+### Usage
+Run the script using:
+
+```
+cd journal-log-ubuntu
+sudo ./journal-log-ubuntu
+```
+
+### Notes
+A crontab entry will be added to perform cleanup of **journalctl** logs. This job runs every **Sunday at 02:00**.
+
+### Post-install
+Nothing to do.
