"Command not found" is quite something different than "it doesn't seem to be working".

Either lspci got installed to a place which is not in your path, or you use a shell which needs rehash to update its directory cache.

Note that you did try to run it normal user. Thus /sbin, /usr/sbin and /usr/local/sbin probably are not in your path.

ok, weird. adding sudo got it to work. pardon my ignorance, but what does that mean exactly? Super Users have a different path than regular users? –  Ramy Nov 2 '12 at 1:18
    
Yes. Binaries used by superusers/root are traditionally stores in /sbin (supervisor binaries). This is an artifact from the time when drives where still very slow. Other artifact from that time are /bin and /sbin (needed to bring the system up. must be on the core disk), /usr/sbin and /usr/bin (usually secondary drives. Could be network mounted). –  Hennes Nov 2 '12 at 1:21
    
is there a way to make any given program available to all users, since it's not strictly a privilege issue? –  Ramy Nov 2 '12 at 1:24
    
The easiest way to do that for a single command is to add a (soft)link to a normal directory. Use ln -s for that. E.g `ln -s /usr/local/sbin/lscpi /usr/local/bin' (Adjust paths as desired and document it). –  Hennes Nov 2 '12 at 1:27
    
great, thanks!! –  Ramy Nov 2 '12 at 2:40
