I’m lazy and so I seek ways to reduce repetitious activities. For instance, I’ve spent a lot of time in a terminal typing Git commands. A few of the more common commands, I’ve aliased. If I want to see a list of branches, I used to type:
Listing Git branches
$> git branch -v -a
But after adding an alias to my bash profile, I simply type
gb. I’ve done this for a few commands like
git commit, which is
gca for the
Occasionally, aliases aren’t enough and when it comes to Git, you can create custom commands that can be referenced like so:
Your custom Git command
$> git my-command
To create a custom command, you first need to create a file named
git-my-command; second, you must place the resultant file on your path. Finally, you need to make the file executable. You can write this file in Bash, Ruby, or Python – it doesn’t matter.
For example, I tend to find myself stashing some uncommitted changes and then later popping those stashed changes onto a new branch. I end up executing the following steps:
A simple Git flow
$> git stash $> git stash branch some_branch
The key step I want to simplify is the last one – I’m lazy and I’d rather not type 4 words. I’d rather type
git unstash some_branch because it saves me one word.
Following the three simple steps I mentioned above, I’ll first create a file in my
~/bin directory called
~/bin directory is in my path because my
.bashrc has this line:
git-unstash script will be simple – it takes an argument (the branch name, i.e.
$1); therefore, the script does a simple check to ensure the branch name is provided.
Custom Git command: unstash
#!/bin/bash ((!$#)) && echo No branch name, command ignored! && exit 1 git stash branch $1
After I’m done writing it, I’ll do a quick
chomd +x and all three steps are accomplished.
Now my new flow is this:
A simple Git flow
$> git stash $> git unstash some_branch
Custom Git commands are that simple to invent – first, create a file named
git-my-command. Next, place it on your path; and, finally, make it executable. Be lazy and carry on, baby!
