Useful Git Commands

Having used Git for a good few years now, over time I have aquired a list of Git commands. Some very frequent and used daily. Other's not so much. But, on a certain occasion and the "uh-oh" moment, I find them rather useful to get me out of a pickle.

So I thought I should share some common Git commands I use.

If you're new to Git, I found Atlassian's Git a good start and provides a very good foundation and understanding.

Branching in Git

Create a local branch from the current branch you are on and switch to this new branch immediately.

git checkout -b <branch>

Example

git checkout -b mybranch

Switch to a branch.

git checkout <branch-name>

Pushing in Git

Push local branch to a remote repository when the branch doesn't exist on the remote repository.

git push -u origin <branch>

Push local branches to a remote repository when the branch already exists on the remote repository.

git push

Checking Status

Check the current status of the branch, including files added, edited, deleted and the branch name.

git status

Merging

Merges the named branch into the current branch.

git merge <branch-name>

Getting latest

Download and get latest changes from a remote repository. E.g. if new branches were created, these will be downloaded as well.

git fetch

Downloads latest changes from a remote repository and merges them to the current branch.

git pull

What's the difference between git fetch and git pull? According to the StackOverflow answer on what is the difference between git pull and git fetch, git pull is performs a git fetch followed by a git merge.

Aborting a Git Merge

When performing a git pull or a git merge and things have gone a bit sideways, you can always abort.

git merge --abort

When git merge --abort doesn't work. You can try to use git reset.

git reset --merge

git reset --hard HEAD

Aborting a Git Rebase

When a git rebase has gone sideways. You can abort using the following command.

git rebase --abort

Undoing or reverting a local commit

If local commits have not been pushed to the remote repository, they can be reverted.

If you know the commit id, you can use the reset command

git reset --hard HEAD <commit-id>

Example if the commit id is be20eb8, then to revert this commit, the command is:

git reset --hard be20eb8

This will revert the commit be20eb8

Or, if you know the number of commits, you can use this.

git reset --hard HEAD~<n>

Where n is the number of last commits you want to revert

Example

git reset --hard HEAD~1

This will revert the last commit.

Hope you found this useful and if I ever discover any new useful Git commands, I'll be sure to add to this post.
