upload pomocou Perl cgi skriptu

Shakal

Ospravedlnujem sa, ze v posledne dni som az prilis aktivny prispievatel co sa tyka tem upload/download skriptov.
Snad vas potesi, ze toto forum pozadujem za jedine, kde dostanem vzdy naozaj dobru radu.

Ale s5 k teme.
Skript, ktory pastujem (vid: nizsie) funguje ako upload pre subory na server. Pocas uploadu sa vo /var/tmp vytvori subor - CGIxxxx (kde xxxx je nejake, nahodne cislo). Ked upload skonci - skript ho prekopiruje do zadefinovaneho direktoria.

Nie som vobec fanusik Perlu, preto chcem poprosit niekoho skusenejsieho, ci by mi mohol/vedel/prepisal skript tak aby nahodny subor, vytvarajuci sa vo /var/tmp/ nemal nazov CGIxxxxx ale nejaky, ktory mu predam napriklad cez formular (rovnako ako predavam napriklad ten email form).

Popripade ak sa to neda - ci je nejaka moznost aby mi skript este pred uploadom vypisal nazov "docasneho" suboru ktory vo /var/tmp vytvara.

Snazil som sa nato prist sam ale o Perle viem toho prilis malo nez aby som sa dopracoval k rieseniu najblizsi tyzden.

Vdaka za kazdu pomoc.
