⚡ Running the Update Script from Anywhere

If you want to use the update script directly in your terminal from any location,
you can move (or copy) it into a directory that’s included in your system’s $PATH,
such as /usr/bin/ or /usr/local/bin/.

🪄 Make It Globally Accessible

1. Move the script to /usr/bin/:

   sudo mv update.sh /usr/bin/

2. Make sure it’s executable:

   sudo chmod +x /usr/bin/update.sh

3. Now you can run it from anywhere:

   update.sh
