Git Essentials

A very good reference that is thorough yet light is https://www.atlassian.com/git/glossary#commands.

Git commands I use most frequently in my work.

Clone a repo

git clone <repo_url>

Rename a branch

git branch -M <new_name>

Checkout a remote branch

git checkout -b <branch_name> <origin/branch_name>

Clear git cache

git rm -r --cache .

Delete local branch

git branch -D <branch_name>

Delete remote branch

git push origin --delete <branch_name>

List remote origin

git remote -v

Change url of remote origin

git remote set-url origin git@github.com:User/UserRepo.git

Delete remote origin

git remote remove origin

Add a remote origin

git remote add origin <remote_url>

Edit previous commit message

git commit --amend

- opens up git editor.

List checkouts one line

git log --pretty=oneline

Go back to a previous commit

 git reset --soft HEAD~1

Reset will rewind your current HEAD branch to the specified revision. In our example above, we'd like to return to the one before the current revision - effectively making our last commit undone.

Note the --soft flag: this makes sure that the changes in undone revisions are preserved. After running the command, you'll find the changes as uncommitted local modifications in your working copy.

If you don't want to keep these changes, simply use the --hard flag. Be sure to only do this when you're sure you don't need these changes anymore.

Go back to the previous commit (hard)

git reset --hard HEAD~1

Go back to a particular commit

git reset --hard 0ad5a7a6
