arsenal asked for a method to join parts of an iso. He did not write that it is a rar archive. I thought if the parts are made by split and uncompressed (filenames archive.iso.001 and archive.iso.002 etc.) cat archive.iso.001 archive.iso.002 >> archive.iso would work. But if it is a rar archive (filenames archive.iso.part1.rar and archive.iso.part2.rar etc.) one could try the following
Code:
sudo apt-get update
sudo apt-get -t testing install unrar
unrar e archive.iso.part1.rar
