Create Swapfile Script

This script allows you to create a swapfile on your Linux system. You can customize the size of the swapfile based on your needs.

Usage

1. Save the script to a file (e.g., create_swapfile.sh).
2. Make the script executable: chmod +x create_swapfile.sh.
3. Run the script: ./create_swapfile.sh.

Script

#!/bin/bash

# Prompt the user for the desired swapfile size (e.g., 2G, 4G, 8G)
read -p "Enter the swapfile size (e.g., 2G, 4G, 8G): " swap_size

# Create the swapfile
sudo fallocate -l "$swap_size" /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

# Add an entry to /etc/fstab to mount the swapfile at boot
echo "/swapfile swap swap defaults 0 0" | sudo tee -a /etc/fstab

# Adjust swappiness (optional)
sudo sysctl vm.swappiness=10
echo "vm.swappiness=10" | sudo tee -a /etc/sysctl.conf

# Display information about the new swapfile
sudo swapon --show

echo "Swapfile created successfully!"
