It helps if you set the Mail-Followup-To header in your email program if possible. If that's not possible it helps to get a better email program. ;) I'll put that header in now and see if that helps. Putting yourself in a Cc: field may help as well. > I recently wrote scripts that relies on relative dates (they do "intensive" > date manipulations).

What *seems* to be the same is actually *not* the same. Note the space between the dash and the one. That is a difference so it does not report the same result! :) See the info manual from coreutils.info, Node: General date syntax. I reached it via 'info date' -> Options for date -> Date input formats. It says there: "Hyphens not followed by a digit are currently ignored." So in practice your first command calculates the current date minus one week: #: date -d "today -1 week" and your second command calculates the current date plus one week: #: date -d "today 1 week" > Should this be reported as a bug (and how)? It's not a bug; it is the behaviour described in the docs. If this would be a real bug, I would recommend the reportbug tool from package reportbug.
