Git happens! 6 Common Git mistakes and how to fix them

This post details six common Git mistakes and their solutions: correcting commit messages (`git commit --amend`), adding forgotten files to the last commit (`git add <file> && git commit --amend`), removing unwanted staged files (`git reset <file>`), undoing commits to a wrong branch (`git branch <new-branch> && git reset HEAD~ --hard && git checkout <new-branch>`), renaming branches (`git branch -m <old-name> <new-name>`), and using `git reflog` as a last resort to recover from corrupted repositories. It also touches on Git repository security and preventing repository bloat.
