Do you know that questions about git get the most views on StackOverflow? I’ve searched a lot on Google how to execute certain actions with git, and this actually slowed me down a lot. There are some actions that we tend to use a lot, so it’s good to learn them. Here are my favorites, learning from friends and internet, hope you find them useful.

Before we begin, you should run git --version to check your current git version, mine is 2.12.2 as in macOS High Sierra. Here is the official git documentation, you can read details about git commands, parameters and new releases of git.

git merge --no-ff master

Find bug in commit history in a binary search tree style:

git bisect start

git bisect good

git bisect bad

Git alias

If there are commands that you use a lot, then consider using git alias. This is how to make alias for git status, then you can just type git st:

git config — global alias.st status

Alias configurations are stored in .gitconfig file, you can learn some cool aliases from thoughtbot and mathiasbynens.

GUI clients

Doing things in command line is cool and faster. However for viewing branches and commits, I find using a GUI client more visualizing and comfortable. You can see a list of all GUI clients here, I myself use SourceTree.

Check before you commit

We usually have some experiment code that we don’t want they to step into our commit. I usually mark my experiment with // but sometimes forget to unstage that.

Starting with 2.9, Git has improvement on its commit hook which makes it globally using hooksPath.

Firstly we nee to create a file called pre-commit, and place it into, for example, /Users/khoa/hooks:

In your project, run git config core.hooksPath /Users/khoa/hooks.

Whenever you commit a file with that pattern, it won’t let you commit. For how to make this work in SourceTree, check:
SourceTree and pre commit hook
*Pre-commit file works perfectly in terminal, but SourceTree seems to ignore it. I use both terminal and SourceTree, as…*medium.com

Where to go from here

This is just scratching the surface of what git can do, if you want to learn more, here are some links to get started.
