Git Commands

Git is a VCS (Version Control System) used by many, including me.


Writing code on a new branch is a great way to experiment with ideas while being able to keep track of your revisions. You might delete an entire branch because your idea didn’t work or you might merge the branch back into the main branch.

git checkout -b branch # create a new branch
git checkout main # switch to a different branch

Git checkout documentation.


Merging allows you to join two or more histories together.

git checkout develop
git merge --no-ff feature/name # no fast-forward - useful for maintaining a branch topology
git commit -m "message [#30]"

Sometimes my branches have too many commits. You can use --squash to combine all of the commits into one when merging.

git checkout feature/name
git merge --squash experiment/idea
git commit -m "implement idea [#24]"

We all make mistakes and sometimes we need to reset a branch to a previous state.

git reset --hard HEAD # reset the files to the last commit
git reset --hard COMMIT_HASH # reset the files to a specific commit
git reset --hard origin/master # reset the files to a remote branch
