-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Andrew McGill on 12/22/2008 1:38 AM: > My guess is that while it would be friendly to provide a similar message for > wc (od, head, tail, etc), it would violate something posixy (and is therefore > imposixable).
It would be possible to add a conditional check, where if POSIXLY_CORRECT is not defined in the environment and a filter app is started with a tty as stdin and stderr (ie. the same criteria for what POSIX requires bash to use for whether a shell is interactive), then we issue a warning to stderr. Normally, we don't like adding additional uses of POSIXLY_CORRECT, but this particular idea may help stave off confusion. Care to write such a patch? It would need to be applied to all of the coreutils that can act as a filter, not just wc. - -- Don't work too hard, make some time for fun as well!
