Hi, > Hi Andy, How do you run growisofs from within cron -i
i'm not Andy but i know of people who use growisofs via cron. So it is not impossible. With said cronruns growisofs gets its input via stdin from some formatter program (e.g. mkisofs) : some_formatter | \ growisofs -use-the-force-luke -dvd-compat -Z /dev/hdc=/proc/self/fd/0 > what environmental variables need setting? All in all, those cron scripts do ensure that HOME and EUID are set, and set PATH to a content as in an interactive shell. Since all three are needed by the wrappers around growisofs there might be no growisofs-specific need for preset environment variables at all. fgrep getenv dvd+rw-tools-5.21.4.10.8/* reveals usage of SUDO_COMMAND, MKISOFS, MEDIAD_GOT_EXCLUSIVEUSE of which none is set in my interactive shell. So obviously they are not mandatory. (My own cron environment is quite generously equipped, so i am not the ideal tester for cron woes.) Did you experience any problems with growisofs and cron yet ? For example this behavior described in man growisofs ? " If the media already carries isofs and growisofs is invoked with -Z option non-interactively, e.g. through cron, it shall fail with "FATAL: /dev/dvd already carries isofs!" Note that only ISO9660 is recognized, you can per fectly zap e.g. an UDF filesystem non-interactively. " If so, then this snippet from growisofs.c might give a clue " * Revision history: ... * 5.2: ... * - undocumented -use-the-force-luke flag to overwrite the media * none interactively; " Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
