Hello Paul, Just thought of informing you. I could not find '--debug' option in the sort help. Sort could not even recognize the option. Currently I am using the following version of sort. Kindly inform if a latest version is available. 0 $ sort --version sort (GNU coreutils) 8.5 Copyright (C) 2010 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later .
