git log --pretty=oneline 710f0f..8a5cbc 

Tip 2

# If you are on your ‘master’ branch and wanted to see each of the commits that are on
# your  ‘experiment’ branch that are not yet merged in, you can run
git log master..experiment --pretty=oneline

# the same (but from any branch included master)
git log ..experiment --pretty=oneline 

# And also if you are on the ‘experiment’ branch and want to see the same information - everything 
# that is on your current branch that have not been merged into ‘master’ yet, you can run this: 
git log master.. --pretty=oneline
