git rebase '' onto 'master' code example

Example 1: what is git rebase

the rebase command integrates changes from one branch into
another. It is an alternative to the better known "merge" 
command. Most visibly, rebase differs from merge by rewriting
the commit history in order to produce a straight,
linear succession of commits.

Example 2: which branch do I "rebase on"

$ git checkout experiment
$ git rebase master
