Script 1: Clean Temporary Files

#!/bin/bash
# Remove all .tmp and .log files in /tmp

echo "Cleaning temporary files..."
rm -f /tmp/*.tmp /tmp/*.log
echo "Temporary files removed."

Usage:

chmod +x clean_tmp.sh
./clean_tmp.sh

Benefit: Keeps your system tidy without manual deletion.

Script 2: Daily Backup of Documents

#!/bin/bash
# Backup ~/Documents to ~/backup/Documents

SRC_DIR="$HOME/Documents"
DEST_DIR="$HOME/backup/Documents"
mkdir -p "$DEST_DIR"

rsync -av --delete "$SRC_DIR/" "$DEST_DIR/"
echo "Backup completed at $(date)."

Immediate insight:

• rsync → copies only changed files efficiently

• --delete → removes files in backup if deleted in source

• Useful for daily document backup

Script 3: Organize Downloads by File Type

#!/bin/bash
# Move files into folders by type in ~/Downloads

DOWNLOADS="$HOME/Downloads"

for file in "$DOWNLOADS"/*; do
    if [ -f "$file" ]; then
        EXT="${file##*.}"
        mkdir -p "$DOWNLOADS/$EXT"
        mv "$file" "$DOWNLOADS/$EXT/"
        echo "Moved $file to $EXT folder."
    fi
done

Benefit: Automatically sorts files by extension (pdf, jpg, mp4, etc.), keeping your Downloads folder neat.

Script 4: Disk Usage Alert

#!/bin/bash
# Alert if disk usage exceeds 80%

THRESHOLD=80
USAGE=$(df / | grep / | awk '{ print $5 }' | sed 's/%//g')

if [ "$USAGE" -gt "$THRESHOLD" ]; then
    echo "Warning! Disk usage is at ${USAGE}%"
else
    echo "Disk usage is normal: ${USAGE}%"
fi

Benefit: Prevents system issues by monitoring disk space daily. Can be automated with cron.

Script 5: Automated Log Archiving

#!/bin/bash
# Archive logs from /var/log to ~/backup/logs

SRC_DIR="/var/log"
DEST_DIR="$HOME/backup/logs"
mkdir -p "$DEST_DIR"

for log in "$SRC_DIR"/*.log; do
    gzip -c "$log" > "$DEST_DIR/$(basename $log).gz"
    echo "Archived $log"
done
echo "All logs archived successfully."

Benefit: Keeps logs compressed and backed up, saving space and organizing historical logs.
