Or you can just hit TAB twice in a terminal to get a long listing of any commands you may give (executables only if they're in your $PATH). But if it's not just a single executable you're looking for, that may not help much.

Coming back to my question, I used to know an Ubuntu command which I put in as sudo (terminal)and it used to work like a magic command which would literally restore and repair my linux installation - I even used it when I bought a new system and transferred my linux hard drive from my previous machine to the new one and this one command actually setup and prepared my linux installation to work smoothly in my new PC - just one command after connecting my h/drive in the new PC.

As was pointed out, 'sudo' is used to run things with superuser (root) privileges, without actually logging in as root. Therefore that isn't helping, except that it tells you needed to run the command with root privileges--which is also evident from the fact that it does some things that modify your system ('fix it'), which should require superuser privileges
Could it be that you ran something like
Code:
dpkg-reconfigure --all
to reconfigure, as it says, all packages? I'm not sure at all if this resolves any (changed) hardware related issues, but it just came to my mind. It might help if you knew whether or not it was Ubuntu (or Debian) related command, or 'general' for any Linux distribution...
