Collection of useful git commands in daily work

useful-git-cmds.md

List some useful git commands.

Git drop some commits in the branch:

git rebase -i HEAD~N

The ~N means rebase the last N commits (N must be a number, for example HEAD~10).
Then, you can edit the file that Git presents to you to delete the offending commit.
On saving that file, Git will then rewrite all the following commits as if the one you deleted didn't exist.

Use push -f to force the push and replace the remote branch with your local one.
