1. Bash Scripting: Log Cleaner#

This script checks the system log, archives old files, and removes everything older than 30 days. Perfect for keeping your server clean.

#!/bin/bash

LOG_DIR="/var/log/myapp"
ARCHIVE_DIR="/var/log/myapp/archive"

# Create archive directory if it doesn't exist
mkdir -p "$ARCHIVE_DIR"

echo "Starting log maintenance..."

# Move logs older than 7 days to archive
find "$LOG_DIR" -name "*.log" -mtime +7 -exec mv {} "$ARCHIVE_DIR" \;

# Delete archived logs older than 30 days
find "$ARCHIVE_DIR" -name "*.log" -mtime +30 -delete

echo "Maintenance complete: $(date)"

2. Installation Procedure#

Follow these steps to deploy the script locally:

  • Step 1: Create the file: touch cleanup.sh
  • Step 2: Grant execution permissions: chmod +x cleanup.sh
  • Step 3: Add to Crontab for automation:
    • 0 0 * * * /path/to/cleanup.sh
