You may try to join them in this way: 1) Put all parts in one place (for example ~/tmp/finalfile) 2) Make sure that there are no other files in this directory 3) Join files. It works, because `split` gives names to files with alphabetical order. find ~/tmp/finalfile | while read file; do cat $file >> finalfile.iso; done; 4) Check md5 sums 5) Now you may delete x* files in ~/tmp/finalfile directory -- WBR, Dmitry. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
