How to create aliases in the macOS Terminal

If you want to create aliases in the macOS terminal (whether you’re using bash or zsh), you can do the following:

  1. In Terminal, run:

    # If you're using bash
    cd && open -e .bash_profile

    # If you're running zsh
    cd && open -e .zshrc
  2. In the opened file, add your alias. For this example, I’ll make a command mtm that opens this website in a browser. There should not be any space between the alias name, the =, and the quoted command.

    alias mtm="open ''"
  3. Save the file.

  4. Restart Terminal.

  5. Now you can run your command.

That’s all you need to do to set an alias in the macOS Terminal.
