Set Alias in Mac

Step 1: Check Your Shell

type command below in terminal to check your shell. It will be either bash(older Macs) or zsh(new Macs).

You will see output like below.

My Shell is zsh

Step 2: Open Your Shell Configuration File

If you shell is zsh, type below command in terminal to open .zshrc file.

code ~/.zshrc

or (if you are using bash)

code ~/.bashrc

I added alias for start development server in my project.

alias d="npm run dev"

After adding alias, save the file and close it.

Step 4: Reload Configuration File

source ~/.zshrc

or (if you are using bash)

source ~/.bashrc

Step 5: Use Alias

Now you can use alias d to start development server.
