Our goals in the terminal should be precision and speed. Speed matters because slow typing is friction between thought and action. Any command you type out manually, or even tab-complete, a few times, is a candidate for a shortcut.
We shortcut commands on the terminal with aliases. Here’s how I keep my list of aliases long and my count of terminal keystrokes low.
I found this trick a long time ago from, I believe, Thoughbot’s Upcase course.
Thank you, Thoughtbot. I call it
typeless, and it’s been in my
years. I run it a few times a month.
# .zshrc # Find commands I type often so I can alias them alias typeless='history n 20000 | sed "s/.* //" | sort | uniq -c | sort -g | tail -n 100'
What’s happening here? This series of events, via piped commands:
To summarize: “Show me the commands that I type most often into the terminal.”
Here are my top ten entries today.
$ typeless 3 gc 3 gnap 3 history 3 history n 20000 3 man sort 4 git st 10 figlet "DONT PUSH" 10 gp 15 git cheddar 33 gap
The goal here is to find commands that are not aliased and aliases them. No
command is too small if it would save time. As you can see, my top three
git cheddar, and
gp, are all aliases themselves:
$ gap # `git add --patch` $ git cheddar # `git commit --amend -CHEAD` $ gp # `git push`
That’s a good sign; most of the time I’m typing far fewer characters than someone without these aliases. Here’s how I created one of these aliases:
# .zshrc alias gap='git add --patch'
Write down your the alias on a Post-It and commit to using it, every time, until muscle memory takes over. Doing this periodically is one of the best investments I’ve made in my programming practice.
Redditor u/number5 shared a great solution for leveraging the aliases you already have. The library alias-tips analyzes your existing aliases and alerts you when you are missing an opportunity to use one.
$ git status Alias tip: git st
Here, I entered
git status but I’ve already aliased that to
git st. Using
my existing alias would be faster and leverages the work I’ve already done.
