My own preference is to get lpd to set environment variables for this sort of thing. That way the values could be effected by other inputs (printcap entries, etc). I don't have any deep-seated objection to your change (and my opinion doesn't really count for much even if I did... :-), but my general preference is that nothing but the lpr/lpd programs should have any idea of the format (or even existence) of the control file. In the specific case of USER and HOST, aren't those already passed as parameters to the filter? We have a somewhat customized print empire here at RPI, but I believe it's true that the distributed lpd starts up a print-filter with '-n <user> -h <fromhost>'. At one point we added another parameter to this list, only to find out that it broke several of the filter scripts we use. Thus, I went with environment variables. :-) --- Garance Alistair Drosehn = gad@eclipse.acs.rpi.edu Senior Systems Programmer or drosih@rpi.edu Rensselaer Polytechnic Institute To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
