If you want to restore a file that has been removed locally, use ‘bzr revert’ instead of ‘bzr update’. If you want to restore a file to its state in a previous revision, use ‘bzr revert’ with a ‘-r’ option, or use ‘bzr cat’ to write out the old content of that file to a new location.</p> <p>The ‘dir’ argument, if given, must be the location of the root of a working tree to update.
