  4. After editing, press Ctrl + X to exit. It will ask if you want to save the changes—press Y for yes, and then press Enter to confirm the filename.

Using vim

vim is another powerful command-line text editor.

  1. Open a terminal window.
  2. Type the following command and press Enter: 
    vim ~/.zshrc
  3. This will open the .zshrc file in the vim editor. Press i to enter insert mode and make edits.
  4. After editing, press Esc to return to command mode. Then type :wq and press Enter to save and exit.

Using TextEdit (GUI)

You can also use macOS’s default text editor, TextEdit, to open and edit .zshrc.

  1. Open a terminal window.
  2. Type the following command and press Enter: 
    open -e ~/.zshrc
  3. This will open the .zshrc file in TextEdit. You can make changes and save the file as you would with any other document.

Using Visual Studio Code

Visual Studio Code is a popular text editor.

  1. First, ensure you have Visual Studio Code installed. You can download it from here.
  2. Open a terminal window.
  3. Type the following command and press Enter: 
    code ~/.zshrc
  4. This will open the .zshrc file in Visual Studio Code, where you can edit and save it.

After Making Changes

Don't forget to source the .zshrc file to apply the changes immediately:
