Check the Handbook for details. > All I really want to do is take my dump file and see the "files" inside it, and do things with those files such as copy or md5sum (not edit). And I don't even know which tool do use to accomplish that. For example, if I took a dump 0 of /usr (which I did), I would like to see the "file" /usr/home/nlandys/.zshrc inside the dump, and then actually see (read) this file and/or copy it over scp or to another filesystem.
