rsync usually will speed up the upgrading of iso files from one to another.
Since the test iso does'nt change their name here is a small script to help
the community.
#!/bin/sh
rsync -av --progress --partial --stats
sunsite.mff.cuni.cz::ftp/OS/Linux/Dist/Fedora.RC/3/i386/iso/FC3-i386-disc* /directory
of isos
the rsync line here is smart wrapped and should be on one line in your command
or bash script file.
here is my output of this command which is saved as the file "iso"
sh iso
SunSITE.MFF.CUni.CZ 2TB archive
