Description

The chown and chgrp commands enforce a check on a valid set of characters for user and group. The set of valid characters does not include space. On some platforms (notably Windows), the space character is acceptable. We've seen this cause test failures in TestFsShellReturnCode when running on Windows if the logged-in user is a member of a group like Remote Desktop Users.
