Creating your own 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 'https://mtm.dev'"
   

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.
