# lets you add currently staged changes to your last commit.
# Exclude the --no-edit option and Git will prompt if you wish to change commit message. 
# This command comes in very handy for those cases when you find out that you need to 
# make a little change after you’ve already committed your changes.
git commit --amend --no-edit

# This is a powerful command that lets us do loads of stuff with commits that are present in our branch.
git rebase -i origin/master 

# lets us delete local branches that were merged into master.
git branch --merged master | grep -v '^[ *]*master$' | xargs git branch -d 

Let’s check what this command does :
git branch --merged master : This command lists the branches that were merged to master.
grep -v '^[ *]*master$' : This part of the command excludes master branch from getting deleted. 
I can’t think of a scenario where you’d want to delete master branch. 
Well, except when your main branch is not master, then maybe you’d want to delete master. 
In that case, don’t forget to replace `master` with your main branch’s name in the above command.
xargs git branch -d : This is what actually deletes your branches.

# save current uncommited changes and restore them on a branch or another commit
git stash
git checkout feature1
git stash pop

git bisect start : Telling Git I mean business.
git bisect bad HEAD : Letting Git know that the bug is alive on HEAD.
git bisect good HEAD~10 : Marking the commit where I’m sure that the bug wasn’t there, as good.
Now, git will pick a commit between the two I provided above and ask me whether the commit is “good” or “bad”. 
It will keep on going and in no time, I can find the culprit. Now, we got to blame someone for this, right?
