Old notes on git
February 16, 2020
Hey Heather, it’s me again.
I found some old notes on
git from when I started using it in a work context
and had to look up everything, every time. I had written them in a Question &
Answer format. I think that helped me remember what was what but it’s difficult
to get back to that state of mind. Anyway, I felt bad just throwing them away so
here are the notes that I took.
I should probably add some caveat about using
--force but I’m going to be lazy
and just say that this sentence serves that purpose.
Questions and Answers
How do I add all the files changed so that they are committed instead of adding them one by one?
git add .
What are the local branches I have?
How do I create a new branch and switch to it?
git checkout -b bugfix/ifonlyhadwetested
How do I delete local + remote branch?
git branch -d bugfix/ifonlywehadtested
git push origin --delete bugfix/ifonlywehadtested
To delete both: do both.
Dang it. There’s a typo (or some other tiny mistake) and I already pushed. Or I just want to add something to the previous commit. How do I do that?
Make changes, and then:
git add .
git commit --amend
git push --force
How do I check X number of log messages?
git log -3
How do I only see the first line of commit message?
git log --oneline
How do I remove all changes in local?
git checkout .
How do I remove untracked files?
git clean -f
How do I switch back to the branch I was just on?
git checkout -
