Change previous commits author/email with filter-branch
## Make sure your local repo settings are correct
git config --local --list
git config --local user.name "author name"
git config --local user.email "name@example.com"
## Change previous n commits
git rebase -i HEAD~n
# choose the commits to change by adding 'pick' or 'reword' (only for changing the message)
git commit --amend --author="Author Name <email@address.com>"
# change first commit in repo

Squashing your commits into one commit without using interactive rebase.

Squashing your commits into one commit without using interactive rebase (https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request#squash-your-changes)

This basically takes the diff of your branch + origin/master and sets them aside for you to "recommit" them.

git fetch -ap # get in sync w/ server
git checkout jscs-disallow-redundant-spaces # switch to the appropriate branch
git reset --hard origin/jscs-disallow-redundant-spaces # get my branch to be exactly the same as what's on the server
MERGE_BASE=$(git merge-base origin/jscs-disallow-redundant-spaces origin/master) # get the commit where your branch originates
git reset --mixed $MERGE_BASE # reset to the point where your branch originates, but put your changes like you just made them
