### git please

```

git config --global alias.please 'push --force-with-lease'

```

Pushing to a remote repository using the force option is dangerous. It basically

rewrites the history by ignoring the upstream branch and replacing it's content

with our local version. This means that any changes that have not been fetched

by the local branch will be erased from history.

This is where the option `--force-with-lease` comes in handy. It checks at least

if the changes/history to be erased has been fetched, doing the force push in a

more **polite** way: `git please`.
