 P.S. If you frequently listed your hardware on a Linux computer, you should consider creating a *bash alias command* for this purpose (assuming your default shell environment is bash). Basic idea is to simplify commands you need to type each time you want to do something. For listing hardware, write a the following in your _$HOME/.bashrc_ file (it's a hidden file):
