When given a branch, git checkout sets the branch we’re on to.When given a file path, git checkout sets to its contents in the index if is provided, git checkout sets to its contents in.Let’s add that our list of what git checkout does:
This checks out the last branch you were on, much like how cd - in your shell changes you back to the last directory you were in. You can do so by calling git checkout with one file path or more: Perhaps you were trying something out and made some changes to the files in your local Git repository, and you now want to discard those changes. Let’s take a look at what git checkout can do, and an alternative (or two) that can make for a friendlier user experience in Git. Learner: What can I run to discard changes to a file?Įven if you have the commands memorized, there have likely been times when you had to pause after typing a git checkout command while you tried to match it with the operation you had in mind (e.g., “I just typed git checkout … to do X, but I thought git checkout does Y, does this really do what I want?") Learner: What do I run to change the branch I’m on? But a single command doing more than one thing might produce a suboptimal user experience for someone learning Git.
I have found git checkout to be a command that I reach for pretty frequently, as it performs more than one operation. If you’re like me and you’ve worked with Git for some time, you might have a couple of commands committed to your memory-from git commit for recording your changes, to git log for sensing “where” you are.
