NB: If you want the quick steps to add aliases to your
zsh, jump down to the section, ”Adding Aliases: The Better Way“.
First, a little backstory: I’m a big fan of aliases. In fact, when I was learning how to use terminal, they were one of the first things I set up for myself and they changed the way I used git. Every command was so much easier to navigate that I never felt a need to stray away from the command line.
When I decided to move to
zsh, one of the first things I wanted to do was configure my aliases.
oh-my-zsh comes with a whole suite of aliases, which are viewable through the
alias command. There are some great defaults, particularly for navigation and
Still, I had a few navigation aliases I wanted to add.
In hunting for how to add an alias, my first Google search suggested using the
alias command. This was straightforward and seemed to work well enough for a while.
$ alias up=‘cd ..’
Woot! It worked!
Then, I’d close the close the terminal and come back and I’d get an error:
zsh: command not found: up.
What the heck?! Sure enough, when I searched through the aliases (using the
up wasn’t there.
When I was adding aliases to bash, I would do so by saving them to the
.bash_profile file (I hear you can also use the
bashrc file). It made sense to me then that the aliases I was adding would wind up in the ZSH equivalent - so, I opened
.zshrc to take a look.
If you’re an
oh-my-zsh user, you may see the following in your config file:
A couple of things struck me about this message:
alias, were not listed there
oh-my-zshencouraged saving them in the
ZSH_CUSTOM, I used the echo command:
And just like that, I knew where I needed to look around.
What I found by navigating through the
oh-my-zsh directory was that plugins, themes, etc., were all stored in files with extension
The ZSH shell then was looking through this file to find all of the aliases that were defined and giving me access to them. Armed with a better understanding of how
oh-my-zsh was finding aliases and functions to access from the ZSH shell, I could now (more) comfortably add my own.
The steps to adding aliases for
oh-my-zsh is as easy as reading the instructions embedded in the docs provided. But, if you’re like me and they weren’t immediately clear, here are the five steps you’ll need:
$ cd ~/.oh-my-zsh/custom
.zshfile. You can name it what ever you’d like, but for testing, I created
#An alias to naviage up one directory level alias up='cd ..'
$ source ~/.zshrc
Voila! Your new custom aliases will now be available!
