Git: how to get a list of all revisions since some commit? -

using rev-list, i've figured out how list of revisions on 1 branch since commit. how can list of revisions on all branches since commit? let's top of repository looks following. how can list of commits since bbbbbbb (commits 3, 4, 5, , 6)? don't care order.

* fffffff 6 * ddddddd 4 | * eeeeeee 5 | * ccccccc 3 |/   * bbbbbbb 2 * aaaaaaa 1 

cdhowie's answer need, returns commits unrelated branches. if expand tree shape, don't want see commit 7 listed.

* 0000000 7 | * fffffff 6 | * ddddddd 4 | | * eeeeeee 5 | | * ccccccc 3 | |/   | * bbbbbbb 2 |/   * aaaaaaa 1 

git rev-list ^bbbbbbb branches...

for example, on test repository:

chris@zack:~/git-test$ git log --all --graph --oneline * 8daff2c f      <-- test * 5f57b15 d | * 764a725 e    <-- master | * 5889800 c |/ * 294908b b * 975d652  chris@zack:~/git-test$ git rev-list ^294908b master test 8daff2c59d8cb966bf399de5027fae85ee016081 5f57b1524afeafbf37984f84fa5fe24ee0ac8501 764a7256d40dbefdb6278443fb80266f00358a37 58898005214607e5c53b45954a98891ea599c037
