e2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
e2undo [ -f ] undo_log device
e2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesys-
tem found on device. This can be used to undo a failed operation by an
-f Normally, e2undo will check the filesystem UUID and last modi-
fied time to make sure the undo log matches with the filesystem
on the device. If they do not match, e2undo will refuse to
apply the undo log as a safety mechanism. The -f option dis-
ables this safety mechanism.
