Creating PRs

git push --set-upstream origin HEAD
git push -u origin HEAD

-u is an alias for --set-upstream. The command creates remote branch with the same name as your current branch and makes it an upstream. It is basically a handy way to create PRs (as we don't need to specify branch-name twice, making typos along the way). This works because of HEAD being a symbolic-ref for the current branch, hence git can obtain branch name from it.

Tagging

1. git push origin --tags
2. git push --tags

1st command pushes only tags to the origin branch.
2nd command pushes only tags to the upstream branch

Don't forget to push branch to the remote after pushing tags by executing the same commands without --tags param.

Grep in history

What I love about CVS/SVN is that it makes code cleaner allowing us not to leave comments through our code but to remove them, leaving in a version control history. Hence, we should stick to the rule Don't leave comments in your code.

After that, there is a simple way to grep history:

git log -p

The command opens a vim-like reader, where you can find text by pressing / and then typing it. Pressing Enter will start searching throughout the whole git history. Pressing n will move you to the next occurrence (once it will find the first one).
