1. Enter bash mode in your terminal by typing bash

2. Open Terminal: Open the Terminal application on your Mac.

3. Edit .zshrc File: You'll want to add a function to your .zshrc file. This file is executed every time you open a new Zsh shell. Type nano ~/.zshrc in the Terminal and press Enter to edit this file using the nano text editor.

4. Add the Function: In the nano editor, add the following function to the end of the .zshrc file:

    #!/bin/zsh
    #Mac Check Update Script - Created By David Osisek
   
   
    echo "Checking for Homebrew Updates..."
    brew update
    brew upgrade
   
    # checks for programming languages and other tools if applicable
    # Python packages:
    echo "Checking for outdated Python packages..."
    pip list --outdated
    # add more languages here as needed 
   
    echo "Remember to check for updates in the Mac App Store."
    echo "Remember to check for updates to third-party applications not managed by $
    echo "Remember to check for any firmware updates in System Preferences."
   
    echo "Checking for macOS System Updates..."
    softwareupdate -l
   

5. This function, check_updates, first uses brew update to update Homebrew itself and brew upgrade to upgrade all installed packages, then uses pip list --outdated to check for any programming language updates, finally it uses the softwareupdate -l command to list available macOS system updates..

6. Save and Exit: To save the file in nano, press Ctrl + O, then press Enter. To exit nano, press Ctrl + X.

7. Reload .zshrc or Restart Terminal: For the changes to take effect, you can either source the .zshrc file by typing source ~/.zshrc in the Terminal or simply close and reopen the Terminal.

8. Run the Command: Now, you can check for updates by typing ~/check_updates.sh in your Terminal.
