The Ubuntu Update Script

A comprehensive Ubuntu update script

. Get the Raw URL:

• After creating, click on the "Raw" button
• Copy the URL (it will look like: https://gist.githubusercontent.com/YOUR_USERNAME/GIST_ID/raw/ubuntu-update.sh)

One-Line Commands to Run

Once you have your raw gist URL, you can use these one-liners:

Option 1: Download and execute directly (less secure)

curl -sSL https://gist.githubusercontent.com/withakay/3834bc9566c272dab6e29c6d2ece9411/raw/ubuntu-update.sh | sudo bash

Option 2: Download, review, then execute (more secure)

curl -sSL https://gist.githubusercontent.com/withakay/3834bc9566c272dab6e29c6d2ece9411/raw/ubuntu-update.sh -o /tmp/update.sh && chmod +x /tmp/update.sh && sudo /tmp/update.sh

Security Considerations

⚠️ Important: Running scripts directly from the internet with curl | sudo bash can be risky. Consider:

1. Always review scripts before running them
2. Use HTTPS URLs only
3. Consider downloading first, reviewing, then executing
4. Keep the gist private if it's for personal use only

Alternative: Create an Alias

For frequent use, add this to your ~/.bashrc:

alias update-system='curl -sSL https://gist.githubusercontent.com/YOUR_USERNAME/GIST_ID/raw/ubuntu-update.sh | sudo bash'

Then you can simply run:

update-system

ubuntu-update.sh
