Frequently asked questions
How do I see every option for lspci?
Run man lspci for the full manual, or try lspci --help for a short summary.
Do I need sudo to run lspci?
Not for your own files. You only need sudo when the command changes something owned by the system or another user.
Is it safe to practise lspci on a live USB drive?
Mostly yes, because a live session starts fresh each time. Be careful with commands that write to your internal disk, such as rm on a mounted drive or dd.
