Extra Superior Git Aliases

Within the final article on this sequence, Superior Git Aliases, we took a take a look at some superior aliases for Git. Nevertheless, the true energy of Git aliases comes from writing customized scripts. These let you construct Git instructions that may do something you may think about.

On this article, I am going to present you how one can create script aliases with Git. We’re going to try a number of superior scripts you need to use for Git which can be tremendous helpful and can prevent a bunch of time.

Script Aliases

We’ll be utilizing Bash for our scripts. Bash is an unpleasant language, nevertheless it has the good thing about working virtually wherever. To your personal scripts, you need to use any scripting language you want.

Should you’re not aware of Bash scripting, do not panic! Whereas among the syntax could look funky, you may principally muddle your method via. (That is not one thing you sometimes hear from a coding article, proper?) I like to recommend studying Be taught Bash in Y Minutes and rifling via Google or Stack Overflow for something that does not make sense.

Step one is to create a file to your script. I prefer to retailer these recordsdata in my Dotfile’s bin listing, however you may put them wherever you want in your pc. Simply ensure it is someplace simple to recollect.

contact bin/git/git-example

Subsequent, you may want so as to add some boilerplate to the highest of your script.

#!/usr/bin/env bash

set -euo pipefail

The primary line known as a shebang), and it tells your pc that the file is a script that ought to be run with Bash. This particular runs the script with Bash. To make use of a special language, substitute bash for one thing else, like ruby or python3.

The second line tells bash to exit if there are any errors, undefined variables, or errors in a pipeline. I do not know why this is not the default in Bash, however at the very least it is simple to arrange with this line.

You could possibly run your script as-is with (bash bin/git/git-example), however who has time to jot down out bash each time they wish to run one thing? As an alternative, make your script executable.

chmod +x bin/git/git-example

Now you may run your script with out prepending bash to it (e.g. bin/git/git-example).

Lastly, you need to add your script to Git’s aliases. Substitute the trail to your script under.

  instance = "!$HOME/.dotfiles/bin/git/git-example"

That is it! Now you may run git instance to run a script that does not do something!

Checklist All Branches

By default, while you run git department, you get the branches you’ve saved regionally. However what if you wish to see all of the branches accessible to you? You may obtain this by including the --all flag to your branches.

git department --all

I prefer to bundle this right into a git-branches script and add just a few extras to it.

#!/usr/bin/env bash

set -euo pipefail

# Solely output shade if the command is not being piped.
if [ -t 1 ]; then
  COLOR="all the time"

git department 
  | column -s ";" -t

Remember to avoid wasting this to a file and make it executable!

This does a number of issues:

  • It solely outputs shade when the script is being run instantly from the CLI. This lets you use git-branches in different scripts.
  • It types the branches by once they had been authored. This places the latest branches on the backside.
  • It lets you go further arguments to the department command utilizing the $@ Bash variable. It will are available in helpful within the my-branches command we’ll add subsequent.
  • It provides some good formatting to your branches. For instance, this is the reason my branches output appears to be like like in my dotfiles repo. This works through the use of a trick with the column command and changing semicolons within the output so the gadgets line up properly.

Add an alias for this command (and a brief alias in case you like brevity).

  branches = "!$HOME/.dotfiles/bin/git/git-branches"
  bs = branches

You are all set! Now you can run git branches (or simply git bs) to see all off of the accessible branches.

Checklist My Branches

The branches command you simply added could be very useful, however while you’re working with a big group, it may be a ache to see everybody’s branches. I prefer to create a second alias that solely contains my branches. You may simply accomplish this with a brand new script.

#!/usr/bin/env bash

set -euo pipefail

# Solely output shade if the command is not being piped.
if [ -t 1 ]; then
  COLOR="all the time"

"$HOME/.dotfiles/bin/git/git-branches" --color="$COLOR" | grep "$(git config consumer.identify)"

This script runs git-branches after which pipes the output via grep to filter it all the way down to the present consumer’s branches.

Create aliases for each of those instructions.

  my-branches = "!git branches | grep -i '$()'"
  my-bs = my-branches

You may scale back the quick alias to git mbs, however I do not as a result of writing git my-bs makes me smile each time I run it.

Stash Staged

Git has a git stash command, which is helpful for setting apart work for later. By default, it solely stashes tracked recordsdata. When you’ve got new recordsdata you wish to stash new recordsdata, it’s a must to embody the --include-untracked flag, or use git stash --all.

What do you do in case you solely wish to stash some of your recordsdata? The built-in method to do that is Git funky.

To illustrate you wish to stash the recordsdata apple and banana, however maintain cherry and date. To try this, you add the recordsdata you do not wish to stash to the index, after which run git stash --keep-index --include-untracked.

git add cherry date
git stash --keep-index --include-untracked

That is unusual as a result of it is the precise reverse method that git commit works. Plus, you now have a few recordsdata floating round in your index that you will have to run git restore on.

To repair this, let’s create a git stash-staged command.

#!/usr/bin/env bash

set -euo pipefail

git diff --staged --name-only | xargs git stash push "$@" --

That is it! This command makes use of git diff --staged --name-only to print out a listing of the entire recordsdata which can be within the index. Then, it pipes these arguments to xargs. xargs splits up the arguments by newlines and passes them to git stash --.

Add your alias, and also you’re executed!


You positive have been writing a variety of aliases these days. Would not or not it’s good if there was a command we may run to record the entire aliases you’ve got created? We are able to add an alias for that!

  aliases = "config --get-regexp alias"

That is All For Now!

That is it! Hopefully, you’ve got loved this text, and you will make good use of the aliases right here.

Do you’ve a favourite Git alias? Let me find out about it down within the feedback!
