Viewing Unpushed Git Commits

If you want to see all commits on all branches that aren't pushed yet, you might be looking for something like this:

git log --branches --not --remotes

And if you only want to see the most recent commit on each branch, and the branch names, this:

git log --branches --not --remotes --simplify-by-decoration --decorate --oneline

You can show all commits that you have locally but not upstream with

git log @{u}..

@{u} or @{upstream} means the upstream branch of the current branch (see git rev-parse --help or git help revisions for details).

This worked for me:

git cherry -v 

As indicated at Git: See all unpushed commits or commits that are not in another branch.

You can do this with git log:

git log origin/master..

This assumes that origin is the name of your upstream remote and master is the name of your upstream branch. Leaving off any revision name after .. implies HEAD, which lists the new commits that haven't been pushed.

All the other answers talk about "upstream" (the branch you pull from).
But a local branch can push to a different branch than the one it pulls from.

A master might not push to the remote-tracking branch "origin/master".
The upstream branch for master might be origin/master, but it could push to the remote tracking branch origin/xxx or even anotherUpstreamRepo/yyy.
Those are set by branch.*.pushremote for the current branch along with the global remote.pushDefault value.

It is that remote-tracking branch that counts when seeking unpushed commits: the one that tracks the branch at the remote where the local branch would be pushed to.
The branch at the remote can be, again, origin/xxx or even anotherUpstreamRepo/yyy.

Git 2.5+ (Q2 2015) introduces a new shortcut for that: <branch>@{push}
