If ran successfully, there will be a new usr folder and a new share folder I believe. Think of a deb as an elaborate zip file for right now. There are paths in this file that will result in folders being created where you ran it. In normal operation this helps the documentation be installed in the documentation folder, the application binary in the application binary section, and so forth. In *nix (linux/unix/etc) you will find that the directory that you are currently in is represented as a dot (.). So if you see the path ./folder it is referencing a folder found in the directory that you are currently in, whereas the path /folder is referring to a folder located at the base or root of the system ('c:\' if you will). You will find the two files in ./usr/bin I believe. Once you have located them it will be: mv ./libstdc++.so.60 /var/lib/install/usr/lib/minimo/libstdc++.so.6 mv ./libstdc++.so.60.0.3 /var/lib/install/usr/lib/minimo/ mv is called: mv frompath topath So in the first example, the file is being renamed as it is moved to another directory. And in the second, we are simply moving the file to a new directory so there is no need to have the filename in topath. * FYI - There are implicit and explicit ways to refer to objects (files/folders/links/etc) in the filesystem. The last command could have been called a few different ways and still work. I prefer explicit because it leaves no room for error when working with important objects. Quite frankly, this release is not there yet. Antonio has been working on this for the last bit, and there is quite some way to go. But seeing as he's even checking in on posts while he is on his vacation, this could take no time at all. Don't know. You're welcome.
