Export the list of commits which are there in one branch but not there in another branch with commit owner bitbucket

• we needs to Export the list of commits which are there in one branch(branch1) but not there in another branch(branch2) with committer id in bitbucket. So Please let me know if any such kind of option available in Bitbucket *

Here's the recipe:

git log --pretty=format:"%h %ae %s" branch1 ^branch2

• Plain branch names (branch1) say which branches' commits to include.
• Branch names prefixed with ^ (^branch2) say which branches' commits to exclude. Beware some shells might need that quoted.
• %h is the short commit hash.
• %ae is the author's email address. (%an would give the name.)
• %s is the commit message (subject).
• The print format is documented in git log --help (actually, all this stuff is documented there).
