Speed-Up Your Workflow With Bash Aliases ← Alligator.io

One of the three great virtues of a programmer is laziness, and typing the same commands over and over again certainly doesn’t sound like proper laziness!

Thankfully, there’s an easy solution: setting up aliases for frequent commands. Here’s how to do it, in a nutshell.

.bash_profile or .profile

If you’re running Bash in the terminal, the most popular shell on Mac and Linux, you can edit a file in your user’s root folder called .bash_profile.

Here let’s use atom to edit the file:

$ atom ~/.bash_profile

Alternatively, on Mac you may already have a .profile:

$ atom ~/.profile

Edit whichever of .profile or .bash_profile already has content, or if neither have content, then it doesn’t matter which one you edit/create.

alias

Define new aliases with the alias command, and define one per line. Here’s an example of useful aliases for the typical git workflow:

alias diff='git diff'

alias a='git add .'
alias add='git add .'

alias s='git status'
alias status='git status'

alias p='git push'
alias push='git push'

myCommit() {
  git commit -m "$1"
}
alias commit=myCommit
alias c=myCommit

Notice how alias commands can’t accept arguments, so we use a function as a workaround to be able to provide our commit message as an argument. With that, we can now use c “commit message” to commit.

Next, save the file, return to the terminal and refresh the Bash environment with the following command:

$ source ~/.bash_profile

Or:

$ source ~/.profile

If you ever forget the aliases that you’ve setup for yourself, simply use the alias command to list the available aliases:

$ alias
