A core feature of Git is the ability to create aliases. This effectively allows you to customize Git's command set. As a developer, of course, you're going to want to do this.

However, lately I've come across numerous claims stating aliasing core commands is the Right Way to use Git. Unfortunately, even Pro Git aliases core Git commands in their examples.

Regardless, this is not the Right Way.

Why? Two reasons: obfuscation and speed.

Obfuscation

While aliases give us freedom, there's no convention for aliasing core commands. So they're all subjective.

While these commands exhibit our personal flare, they've lost their meaning. Sure git up sounds cool and might impress your coworkers. But they have no idea what it does and it isn't available on their setup.

Speed

The primary motivation for aliasing core commands is speed. Oh, the need for speed. Anything to save a few keystrokes. But how many keystrokes are you really saving by aliasing core Git comamnds?

Let's compare some common aliases against command completion.

With the exception of git status, command completion tied or beat aliases. In addition, command completion also completes references and options. So command completion saves keystrokes across all commands, not just aliases.

In the end, aliases are a useful feature. But stop aliasing core Git commands. Instead, use command completion as a clearer and often faster alternative.

Reserve aliases for Git commands you run frequently and require options. For example, here are my current aliases. Two alias long git log commands and the others compliment Git's command set with additional custom commands.

Update
There seem to be confusion about scope. My suggestion is not to create Git aliases for core Git commands. This includes things like git st, git co, git ci as shorthands for git status, git checkout, git commit respectively. It does not include Git aliases in general or system aliases.
