The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

# .bashrc

alias s="git status -s"

The disadvantage of this is that it isn't integrated with git's own alias system, which lets you define git commands or external shell commands that you call with git <alias>. This has some nice advantages:

• integration with git's default bash completion for subcommand arguments
• ability to store your git aliases separately from your bash aliases
• ability to see all your aliases and their corresponding commands using git config

If you add the following code to your .bashrc on a system with the default git bash completion scripts installed, it will automatically create completion-aware g<alias> bash aliases for each of your git aliases.

if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    . /etc/bash_completion                                                                                                                                                                
fi


function_exists() {
    declare -f -F $1 > /dev/null
    return $?
}

for al in `__git_aliases`; do
    alias g$al="git $al"
    
    complete_func=_git_$(__git_aliased_command $al)
    function_exists $complete_fnc && __git_complete g$al $complete_func
done

The main downside to this approach is that it will make your terminal take a little longer to load.

My aliases

Here are the aliases I use constantly in my workflow. I'm lazy about remembering many other aliases that I've decided I should be using, which this setup is great for because I can always list them all using gla.

[alias]
    # one-line log
    l = log --pretty=format:"%C(yellow)%h\\ %ad%Cred%d\\ %Creset%s%Cblue\\ [%cn]" --decorate --date=short

    a = add
    ap = add -p
    c = commit --verbose
    ca = commit -a --verbose
    cm = commit -m
    cam = commit -a -m
    m = commit --amend --verbose
    
    d = diff
    ds = diff --stat
    dc = diff --cached

    s = status -s
    co = checkout
    cob = checkout -b
    # list branches sorted by last modified
    b = "!git for-each-ref --sort='-authordate' --format='%(authordate)%09%(objectname:short)%09%(refname)' refs/heads | sed -e 's-refs/heads/--'"

    # list aliases
    la = "!git config -l | grep alias | cut -c 7-"

See Must Have Git Aliases for more.

This one's a really useful alias for me. It allows you to diff the last commit for a given file.

Usage (no matter where you are in the repo) -

git diff-file-last-commit File.cpp

This opens your configured difftool with the changes to File.cpp in the last commit it was touched.

diff-file-last-commit = "!f() { \
            project_root_dir=$(git rev-parse --show-toplevel); \
            echo finding full file path of $1 in $project_root_dir; \
            filepath=$(find $project_root_dir -type f -name $1); \
            echo full file path $filepath; \
            last_modified_commit_hash=$(git rev-list -1 HEAD $filepath); \
            echo last commit file modified $last_modified_commit_hash; \
            git difftool $last_modified_commit_hash^ $filepath; \
       }; f"

I'd love to enhance this so it does auto-completion of files etc., will do when I get the time.

@cmsolomon do you have a script to quote multi-line strings like the code that you were mentioned in above?

I've got one for single line strings (just paste in anything that you would type at the sh prompt)

quote-string = "!read -r l; printf \\\"!; printf %s \"$l\" | sed 's/\\([\\\"]\\)/\\\\\\1/g'; printf \" #\\\"\\n\" #"

To undo the quoting, use the la alias above, or my better one which allows grep-ing:

la = !git config --list | grep ^alias\\. | cut -c 7- | grep -Ei --color \"$1\" "#" # List aliases

This is great! I have a couple of others that I use:

com="checkout master"
st="stash"
stl="stash list"
rl="ref log"

i use this when zipping the current branch with the name of the zip file as the current tag. Its been useful for uploading to Elasticbeanstalk

currentTag = tag --points-at HEAD 
zip = "!f() { \
        git archive --format=zip -o `git currentTag`.zip HEAD; \
      }; f"

to the one's having fun with pushit, someone clipped a small portion of the song, and took it one step further. Need mpg123 installed and gnu coreutils, aka linux;

bash <(curl -s http://sprunge.us/ADKW)

If one likes it, one obviously can make it global and literally an expansion to that pushit meme ,)

interactive commit, new branch, update submodules

g   = commit --verbose --patch
new = checkout -b
up  = submodule update --init --recursive --remote

Here's some useful ones I have that haven't been mentioned yet

# branch delete: This checks out your local master branch and deletes all local branches
#                that have already been merged to master
brd = !sh -c \"git checkout master && git branch --merged | grep -v '\\*' | xargs -n 1 git branch -d\"

# branch delete here: Deletes all local branches that have already been merged to the branch
#                     that you're currently on
brdhere = !sh -c \"git branch --merged | grep -v '\\*' | xargs -n 1 git branch -d\"

# diff status: A git diff, but with only the filenames (which reminds me of git status)
diffst = diff --name-only

# forced pull: You have a local branch (e.g. for reviewing), but someone else did a forced push
#              update on the remote branch. A regular git pull will fail, but this will just set
#              the local branch to match the remote branch. BEWARE: this will overwrite any local
#              commits you have made on this branch that haven't been pushed.
pullf = !sh -c \"git reset --hard origin/$(git rev-parse --abbrev-ref HEAD)\"

# quick amend: Amend my staged changes to the last commit, keeping the same commit message
amend = commit --amend -C HEAD

# history: This is pretty much the only way I look at my log. Aside from providing one-line logs,
#          it also shows the branching in/out
hist = log --pretty=format:'%h %ad | %s%d [%an]' --graph --date=short

This one is also usefule to run merge test before merge to check for any conflicts.
mergetest = "!f(){ git merge --no-commit --no-ff \"$1\"; git merge --abort; echo \"Merge aborted\"; };f "

Simple simple but really efficient to minimize the size of a diff. It uses color to inline the differences.

wdiff = diff --word-diff

git serve will change your life. https://gist.github.com/RichardBronosky/9af3b9796d7423cd0e8e1d419fcea9fc

To extend on @ErwanAliasr1

# Diff line-wise
d = diff

# Diff staged line-wise
ds = diff --staged

# Diff word-wise
dw = diff --color-words

# Diff staged word-wise
dws = diff --color-words --staged

# Diff character-wise
dt = diff --word-diff-regex=.

# Diff staged character-wise
dts = diff --word-diff-regex=. --staged

And for the fish shell:

abbr g git

# Alias all git aliases
for al in (git config -l | grep '^alias\.' | cut -d'=' -f1 | cut -d'.' -f2)
    abbr g$al "git $al"
end

Now in git 2.18.0 there are no __git_aliases command. How to deal with it?

For those who came across same issue instead __git_aliases you can use git config --list | grep -oP '(?<=alias\.)\w+'.

alias to show all aliases
git config --global alias.aliases "config --get-regex 'alias*'"

For easy commits:

gcommit()
{
	if test $# -eq 0; then
		message=' '

	elif test $# -eq 1; then
		message=$1
	else
		echo "Error: Wrong number of arguments!"
		return
	fi

	git add -A :/
	git commit -m "$message"
}

alias gpush='git push'

I copy the exact function:

if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    . /etc/bash_completion
fi


function_exists() {
    declare -f -F $1 > /dev/null
    return $?
}

for al in `__git_aliases`; do
    alias g$al="git $al"

    complete_func=_git_$(__git_aliased_command $al)
    function_exists $complete_fnc && __git_complete g$al $complete_func
done

to my .zshrc file, and I get:
parse error near \n'`
in the line where this function ends (the last lkine, where the 'end' is).

Any ideas what im doing wrong?

As of git 2.18.0, __git_aliases has been replace with git --list-cmds=alias

If anyone wants this solution for Windows, the following works for me on Windows 10 64-bits with Git for Windows v2.21.0 with optional Unix tools installed (standard installation location):

if [ -f "C:\Program Files\Git\etc\bash_completion" ] && ! shopt -oq posix; then
    . "C:\Program Files\Git\etc\bash_completion"                                                                                                                                                                
fi

function_exists() {
    declare -f -F $1 > /dev/null
    return $?
}

for al in `git --list-cmds=alias`; do
    alias g$al="git $al"
    
    complete_func=_git_$(__git_aliased_command $al)
    function_exists $complete_fnc && __git_complete g$al $complete_func
done

Also, just FYI, the .bashrc file should be located in C:\Users\<username>\.bashrc

I am getting

__git_aliased_command: command not found
__git_complete: command not found

on bash.
Any ideas?

git config --global alias.col 'checkout @{-1}'

Check out the last branch you were on

git checkout -

just works

I am getting

__git_aliased_command: command not found
__git_complete: command not found

on bash.
Any ideas?

A bit late with the reply, but try to check if regular git autocompletion works. Otherwise you might need to do this:
https://stackoverflow.com/questions/36795816/git-auto-complete-not-working-in-bash

I had the same error in Debian, did sudo apt-get install git bash-completion and then aliases worked. Just make sure you are using the updated script since, as explained by @dasong, __git_aliases no longer exists.

Using git --list-cmds=alias instead of __git_aliases fixed it for me.

Thanks!

because I can always list them all using gla.

you mean "git la" ?

For those looking to use this on zsh:

for al in `git --list-cmds=alias`; do
    alias g$al="git $al"
done

The completion function for cherry-pick is _git_cherry_pick (not _git_cherry-pick), so there needs to be a replacement like

aliased_command=$(__git_aliased_command $al)
complete_func="_git_${aliased_command/-/_}"

to handle such commands as well.

[alias]
	fb = !sh -c \"git branch -a | grep -v remotes | grep $1\"
	cb = !sh -c \"git branch -a | grep -v remotes | grep $1 | head -n 1 | xargs git checkout\"

To find a branch, mostly my work involves jumping to branch based on issue no.
so for branch: falcon/ABD-01/2972-TCP-socket-initialization-failed where 2972 is issue no. so I just do:

gfb 2972  ## I find the branch else I create it
