I use few aliases for Git in my terminal (this also works when using Vim fugitive). I thought I would share some of them here, but you will likely find more useful aliases in Mathias Bynens dot files.

The following should naturally go under the [alias] section of your Git config fail (mine is located in ~/.config/git/config).

• l = log --pretty=format:'%<|(16)%C(yellow)%h %Cblue%ad %Creset%s%Cgreen [%cn] %Cred%d' --decorate --date=short --graph: This is a customized version of git log to pretty print the history with minimal information. It can be used to print only the latest 5 commits using git l -n 5.
• d = "!f() { git diff --patch-with-stat HEAD~$1; }; git diff-index --quiet HEAD -- || clear; f": This is a specific diffing tool, whereby you indicate the number of past commits you want to diff against HEAD, e.g., git d 3 will shows what has changed during the last 3 commits.
• ca = !git add -A && git commit -av: git ca will simply add all modified files and prompt for a commit message using your preferred editor.
• bo = "!f() { git checkout -b \"$1\" 2> /dev/null || git checkout \"$1\"; }; f": Useful to switch to a branch or to create one if it doesn’t exist yet. Be careful with typo, though.
• amend = commit --amend --reuse-message=HEAD: git amend will simply reuse the last commit message for newly staged files. I often use it when I forgot to stage a file or for minor fix on already staged and commited files.
• fixup = "!f() { git rebase -i HEAD~$1; }; f": Rebasing made easy, since you just have to say git fixup 3 to interactively rebase using the last 3 commits. I use it mostly for squashing commits together.
• fc = "!f() { git log --pretty=format:'%C(yellow)%h %Cblue%ad %Creset%s%Cgreen [%cn] %Cred%d' --decorate --date=short -S$1; }; f": Handy grep utility to look up for specific pattern in past commited core files.
• fm = "!f() { git log --pretty=format:'%C(yellow)%h %Cblue%ad %Creset%s%Cgreen [%cn] %Cred%d' --decorate --date=short --grep=$1; }; f": Same but for searching in commit messages instead of files. This is quite useful when you leave FIXME or WIP instructions in your commit messages.
• cleanup = "!git branch --merged | grep -v '\\*' | xargs -n 1 git branch -d": Cleanup branches that ar eno longer needed because they are already merged into the trunk.
• catchup = !git fetch upstream && git rebase upstream/$(git symbolic-ref --short HEAD): Fetch the latest changes from a repository you track in your remote and merge it with yours local copy, assuming it is the same branch as the one you are currently onto (be it a master/main or gh-pages branch).
• unstage = reset HEAD and unmerge = reset --hard HEAD: Well, you get it, everybody makes mistakes, especially when using Git.
• here = !git init && git add . && git commit -m \"Init repo\": Shorthand to initialize a barebone repository in the current working directory.

Hope you’ll find it useful! And many thanks to all the cool guys on Github from whom I stole several of these ideas.
