Of course. My stand-alone example was wrong. However, with 'exec' it fails the same way. On the other hand, Eric's suggestions to use nice or nohup do work: $ PATH=. /bin/sh -c 'exec mknod --version'|head -1 /bin/sh: mknod: --: unknown option /bin/sh: mknod: usage: mknod [-m mode] name [b | c] major minor /bin/sh: mknod: usage: mknod [-m mode] name p $ PATH=. /bin/sh -c '(exec mknod --version)' | head -1 /bin/sh: mknod: --: unknown option /bin/sh: mknod: usage: mknod [-m mode] name [b | c] major minor /bin/sh: mknod: usage: mknod [-m mode] name p $ PATH=. /bin/sh -c 'nice mknod --version' | head -1 mknod (GNU coreutils) 6.10.188-7cb24 $ PATH=. /bin/sh -c 'nohup mknod --version' | head -1 nohup: ignoring input and redirecting stderr to stdout mknod (GNU coreutils) 6.10.188-7cb24 $ So I'll go with nice.
