Atypical Git Commands

git stash: stores the latest changes you've made to a secret chamber and returns your working directory to the match the last commit (can get it back by using git pop)
git stash apply: restores the git stash, potentially on top of a different commit
git shortlog: summarizes git log output (commits re grouped by author and title)

git commit --amend: fixes most recent commit, can edit or combine staged changes with the previous commit 
git reset --hard(with commit number) : takes your current branch back to point of commit number (all changes after this commit are discarded)
git reset --soft : doesn't change index file or working tree but resets the head to commit, leaves all changed files as changes to be committed
git reset --hard HEAD~2: resets to a different head 
Three ways to display git log: 
1. git log --stat : allows you to see changes in modified file (kind of like when you do a git pull origin master)
2. git log --prety= oneline: Allows you to see it in one line and neat
3. git log -p: lets you see the difference in each commit
