How do I create a Bash alias?

I just open zshrc with sublime, and edit it.

subl .zshrc

And add this on sublime:

alias blah="/usr/bin/blah"

Run this command in terminal:

source ~/.zshrc

Done.

You can add an alias or a function in your startup script file. Usually this is .bashrc, .bash_login or .profile file in your home directory.

Since these files are hidden you will have to do an ls -a to list them. If you don't have one you can create one.

If I remember correctly, when I had bought my Mac, the .bash_login file wasn't there. I had to create it for myself so that I could put prompt info, alias, functions, etc. in it.

Here are the steps if you would like to create one:

1. Start up Terminal
2. Type cd ~/ to go to your home folder
3. Type touch .bash_profile to create your new file.
4. Edit .bash_profile with your favorite editor (or you can just type open -e .bash_profile to open it in TextEdit.
5. Type . .bash_profile to reload .bash_profile and update any alias you add.
