Update: Linux-sokszorosito...

A script velemenyem szerint annyira specifikus es kezdetleges, hogy nincs ertelme beemelni a wikibe.
Ha en irnek egyet, ugy kezdenem, hogy legalabb ne csak Linuxon legyen kepes futni. Rengeteg resz van, aminek biztosan csak Charlie-eknal van ertelme, ezeket meg sem kisereltem modositani. Minden kritika mellett, amit hozzairtam, tisztaban vagyok vele, hogy nem volt tobb ido az eredetit csiszolgatni.

Hasonlo celokra Hubert Feyrer g4u-jat ('Ghost for Unix') szokas hasznalni, ami a dd-re alapoz, sajnos mindenfele optimalizalas (pl bs= megadasa) nelkul, igy nem a leggyorsabb. Viszont script, igy konnyen fel lehet hasznalni.

FIGYELEM! A scriptet jelen formajaban NEM teszteltem, fogalmam sincs, hogy mukodik-e egyaltalan, van-e benne szintaktikai hiba vagy barmi egyeb!!!
