I've been working with git for the last few years and I have some tricks to make my every day use a bit easier. So I wanted to share them and hopefully help someone with it.

This article is aimed at somebody who has already some experience using git.

Get a file from another branch without changing your current branch

When you are working on a feature branch but you need a file from another branch, you could stash your changes, switch to the other branch and copy the file. But you can do this with a single action.

git checkout <other-branch> -- path/to/file

Partial adds

You did a lot of changes but you want to commit them in separate commits. Look no further!

git add -p

Highligh word changes with git diff

Full diffs can give not enough information. Sometimes all text was on a single line so you won't see the exact difference. So you can use the option --word-diff

git diff --word-diff

Better logging

A cleaner git log output with colors and a tree visualization.

git log --pretty=format:"%h %ad | %s%d [%an]" --graph --date=short

Output:

* b034f07 2016-11-22 | Merge feature-2 into master |\ | |\ | | * 914ab62 2016-11-22 | More changes * | | 43941b5 2016-11-22 | New feature 2 |/ / * | 7d191da 2016-11-22 | Starting on feature xxx |/ * 127c16f 2016-11-22 | bugfix xxx

or without the custom format

git log --oneline --decorate --graph

Using git bisect to track down bugs

Sometimes it is hard find the commit which caused a certain issue. You could manually checkout out specific commits and hope you choose somewhat right or you use the bisect tool.

git bisect start git bisect good {{good-commit-hash}} git bisect bad HEAD

Bisect will checkout a commit in the middle between good-commit-hash and HEAD . Then you will have to review this commit and mark it as good or bad.

git bisect good/bad

This will continue until you've found the commit which caused the issue. Run the following commands to return to the original state and get a summary from git bisect .

git bisect reset git bisect log

Git aliases

Git supports aliases for git commands, this way you tweak existing command to perform better or abbreviate commands. You can add aliases by editing your .gitconfig file or by running the git config command. These are a few examples, check out my gitconfig for more aliases and custom configs.

git config --global alias.stat = status git config --global alias.remotes = remote -v

Command autocompletion

The git repository already ships with some autocompletion helpers, you will only have to download and activate them. See the autocompletion directory for the different available formats.

Execute the following commands to enable autocompletion on your git commands:

cd ~ curl -O https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash mv git-completion.bash .git-completion.bash

Finally place this line in your .bashrc file and you are good to go!

source ~/.git-completion.bash

Ignore whitespace changes

When checking a diff or checking code with git blame it's possible you want to ignore whitespace changes. Just use the -w option

git diff -w git blame -w

Bonus: use legit

Legit is a complementary command-line interface for Git, optimized for workflow simplicity. It is heavily inspired by GitHub for Mac. It will add some extra functionality to your git installation.

git sync # Syncronizes current branch. Auto-merge/rebase, un/stash. git switch <branch> # Switches to branch. Stashes and restores unstaged changes. git publish <branch> # Publishes branch to remote server. git unpublish <branch> # Removes branch from remote server. git branches # Nice & pretty list of branches + publication status.

See git-legit.org for more information.
