After Installation · Scripts
Post-Install Scripts
These scripts automate the post-installation steps from Chapter 2. Copy and paste into your terminal — each is commented so you know exactly what it does.
01-update-system.sh
Updates all packages and removes unnecessary dependencies. Always run this first after a fresh install.
#!/bin/bash # 01-update-system.sh — Update Ubuntu after fresh install # Website: nextsteplinux.com/lf2 echo "Starting system update..." # 1. Refresh package list from all repositories sudo apt update # 2. Upgrade all installed packages # 3. Handle dependency changes (removes old deps if needed) # Using 'full-upgrade' often covers what 'upgrade' does, but running both is safe. sudo apt full-upgrade -y # 4. Remove packages no longer needed sudo apt autoremove -y # 5. Clean up downloaded package cache to save space sudo apt clean echo "System updated successfully!"
02-install-essentials.sh
Installs the tools used throughout the rest of the book. Run after updating the system.
