How to undo bzr add

Question

Sometimes I type bzr add and don't notice that I am not in the root of the branch but an ignored sub-folder. This then adds all files in that folders - often it is a build folder, with lots of files. Hence the question: how to undo a bzr add.

Answer 1

There is built-in way without need of xargs: bzr remove --new --keep

Answer 2

This answer is shamelessly stolen from here to make it more accessible (to me as well).

This will undo an erroneous bzr add:

bzr added -0 | xargs -0 bzr rm --keep
