Server Log Cleaner

A simple bash script that deletes log files older than 14 days from standard Linux and ZimaOS paths, helping keep your server's disk usage under control. Made with laziness by Server Log Cleaner Dev team(me) 🦥

Usage

Make the script executable and run it:

chmod +x Code-log-Cleaner.sh
sudo ./Code-log-Cleaner.sh

Always do a dry run first to preview what will be deleted before actually removing anything:

sudo ./Code-log-Cleaner.sh --dry-run

Options

Flag	Description
--dry-run	Preview files that would be deleted without removing anything
--help	Show usage information

What It Cleans

By default the script scans these directories:

Path	Purpose
/var/log	Standard Linux system logs
/root/.casaos/logs	ZimaOS / CasaOS core logs
/var/lib/casaos/logs	ZimaOS service logs
/DATA/AppData	Docker app data

It only targets files with log-related extensions (.log, .gz, .old, and numbered rotations like .1–.5), so your actual data files are safe.

Configuration

At the top of the script you can change:

• MAX_AGE_DAYS — how old a file must be before it's deleted (default: 14)
• DRY_RUN — set to true to always run in preview mode (default: false)
• LOG_DIRS — add or remove directories to scan
• LOG_PATTERNS — add or remove file extensions to target

Automating with Cron

To run the script automatically every Saturday at 3 PM:

sudo crontab -e

Add this line:

0 15 * * 6 /path/to/Code-log-Cleaner.sh >> /var/log/log_cleaner.log 2>&1

Requirements

• Bash
• sudo / root access
• numfmt (part of GNU coreutils, installed by default on most Linux systems)

Notes

• This has been tested, and it works well
• The amount it cleans will probably fill up after a couple hours idk
• Friend that tested it said that there were so many logs on his server it filled up again after 10 seconds
