Here is an excerpt from the manpage for git rev-parse:
This set operation appears so often that there is a shorthand for it.
"r1..r2" is equivalent to "^r1 r2". It is the difference of two sets
(subtract the set of commits reachable from r1 from the set of commits
reachable from r2).
A similar notation "r1...r2" is called symmetric difference of r1 and r2
and is defined as "r1 r2 --not $(git-merge-base --all r1 r2)". It is the
set of commits that are reachable from either one of r1 or r2 but not
So for three dots: if M and B have diverged it will show all commits that are unique to both
branches (reachable from either M or B) , but not those common to both branches
(not reachable from both).
For two dots: indeed it will show all commits unique to only B, i.e. those
introduced in B, but not yet merged into M.
Is this what you meant?
