Zero all files in /var/log/ courtesy of chatgpt + some of my tweaking to make stuff work.

This repository contains a script, systemd service, and systemd timer that work together to periodically truncate log files in the /var/log directory.

Logs can accumulate over time and consume disk space. This script automates the process of truncating log files, effectively clearing their content while retaining the file structure. The systemd service and timer ensure that this truncation process occurs regularly, preventing log files from growing excessively.

1. Clone the Repository

   Clone this repository to your local machine:

   git clone https://github.com/your-username/log-truncation-service.git
   cd log-truncation-service
   

Create the Service Unit File

Create or modify the systemd service unit file:

sudo nano /etc/systemd/system/truncate-logs.service
Add the following content to the file:

[Unit]
Description=Periodically truncate log files in /var/log
After=network.target

[Service]
Type=simple
ExecStart=/path/to/your/script.sh
WorkingDirectory=/path/to/your/script/directory
StandardOutput=syslog
StandardError=syslog

[Install]
WantedBy=default.target

Save and close the file.

Create the Timer Unit File

Create or modify the systemd timer unit file:

sudo nano /etc/systemd/system/truncate-logs.timer Add the following content to the file:

[Unit]
Description=Timer for truncating log files

[Timer]
OnCalendar=*:0/5
Persistent=true
Unit=truncate-logs.service

[Install]
WantedBy=timers.target

Save and close the file.

Reload systemd and Enable the Timer

sudo systemctl daemon-reload ;
sudo systemctl start truncate-logs.timer ;
sudo systemctl enable truncate-logs.timer ;

Check the Timer Status

To verify that the timer is running:

sudo systemctl status truncate-logs.timer
The script will now run once every 5 minutes to truncate log files in the /var/log directory.
