Git is an amazing tool for version-control and open-source collaboration (though many companies are now using it too!). I think that most people should be able to use Git, especially if it's a requirement for them at work or school. Below are 5 Git commands everyone should know.
git reset --hard [commit hash]— This is fantastic as a last resort for when you've really screwed up. Generally, I've only used this when I've tried out a dumb idea (thinking it was good), merged it into my main branch, and then realized that it was, in fact, a dumb idea in the first place.

git checkout -- [filename]— If you're ever in a situation where you've made so many changes to a file that you think it's just better to scrap them all, this is the command.
git checkout -- [filename]will undo any uncommitted changes to a file (or a set of files). You might want to read more about this.
git rm [filename]— This command gets git to stop tracking a file or a set of files. It's pretty useful for removing a file from the working directory and removing it from git's tracking. You might want to read more about this.
git config --global alias.[aliasname] [command]— This is very helpful if you hate typing a lot.
git aliasallows you to create short-hands for common git commands. For example,
git config --global alias.nbr "checkout -b"allows you to do
git nbr my-branchto create a new branch called
git checkout -b my-branch(I made this exact alias myself). You might want to read more about this.
git revert— OK, so I'll admit, I've never used this once, but I think the command is pretty useful. Given a set of commits, it'll undo those changes and record that revert in a commit. Again, I've never used it, but I can think of many cases where development can go so awry that it's necessary. You might want to read more about this.
