Hi gang, I would appreciate some tips on doing a couple of simple things with iso files. I have not done them before, and cannot find what I need to know in man pages etc. If you could post a "howto" for the following tasks I would appreciate it: 1. I have the four iso files for SW 10.0 (thanks, Greg) plus the associated md5 files. How do I verify the intactness of my downloads? The man page seems to suggest I should have a command called "md5" unless I am misreading it, but there ain't no such animal on my system. Related to that, I will then burn a set of CD's and will need to verify those burns as well. 2. There should be a way to "open" those iso files, copying or converting them to the corresponding files and directories, without first burning the CD's and then mounting and copying the contents back in again. How would you do that, going directly from an iso file to a directory structure on the HD?
