bunu ben de cok aramistim ama bulamayinca mecburen kendim yazdim.
asagida paste edecegim script, input filter olarak kullanildiginda sayfa
sayip eger sayfa yeterli degilse joblari remove edebiliyor.
gonderilen dosya text ya da postscript olmali.
ve de printer spooler'i olarak LPRng kullaniyorum (slackware contrib
directorysinde bulabilirsiniz. ftp.astart.com'da da doclari var ve benim
gordugum en iyi printer spooler'i)
yazdigim quota paketi iki bolumden olusuyor. birincisi quota'yi kontrol
eden ve sayfalari sayan bir input filter (sayfa sayma isini de o yapiyor),
digeri de eger print isi kabul edilirse quotayi arttiran bir c programi.
ikisi de cok acemice yazilmis gibi gorunebilir :) uzerinde calistiklarini
gordukten sonra hic ugrasmadim. sacma buldugunuz yerleri duzeltir bana
maillerseniz sevinirim.
bu arada, quota paketi input filter olarak calismasinin artindan
CTI-ifhp'nin /usr/local/lib/filters altindaki ifhp executable dosyasini
cagiriyor. eger input filter kullanmayacaksaniz (laser printer falan
degilse) bunu cat yapabilirsiniz.
Bu iki kucuk programi ayni zamanda solarislerde de kullaniyorum. onlarda
da sorunsuz calisiyor.
Umarim isinize yarar.
