I'm not sure if you can assume /usr/bin/env exactly in this position on every UNIX system. In order to gain maximum portability, keep things simple and try to use sh as scripting shell. If that's not possible, you could add a check (using "which") for bash's availability, outputting to stderr if bash is not present, just like a kind of "wrapper script" that calls your bash specific script. Maybe that's not very elegant, but it seems to be a good solution. > By the way, this also works with Perl as you no doubt know.

Adding symlinks to structures controlled by the package management system or the OS itself can lead into problems. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
