Hi Matt, named-checkzone wants a file, so give it a "file": named-checkzone ripe.net. /dev/stdin < ripe.net.zone Note that it would work with "cat file | ..." but I absolutely hate the cat-pipe combination. I've been known to mark down interviewees who offer a solution that involves cats and pipes :) If you want to feed a compressed zone file, then of course a gzcat-pipe combination will work, eg: gzcat ripe.net.zone.gz | named-checkzone ripe.net. /dev/stdin Finally, if you're running your scripts under bash, then bash offers a very neat feature: named-checkzone ripe.net. <(gzcat ripe.net.zone.gz) The "<(...)" construct in bash runs the command inside the parantheses, and sends its output to an ephemeral file of the form /dev/fd/42. So the above command becomes: named-checkzone ripe.net. /dev/fd/42 and named-checkzone reads the "file" /dev/fd/42, getting the decompressed data.
