 how to grep git source code
 ```
 git grep <regexp> $(git rev-list --all)
 ```

 how to grep git commit msg
 ```
 <your fav git log alias> --grep="foo"
 ```

 git push a few commits to origin
 ```
 git push origin 91143c3:fix-52-2
 ```
 where 91143c3 is the last commit you want to push, and fix-52-2 is the branch on origin to push to.
 this actually pushes all child commits of 91143c3 to origin because commits are chained together.
 so, if you'd like to push a range, push the head commit with this technique.
