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. You might want to read more about this.
• 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 alias allows 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-branch to create a new branch called my-branch instead of 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.
