A very common thing linux users struggle with is to find what hardware has the OS detected and how well. Because unless the OS is aware of the hardware, it might not be using it at all. And there an entire ocean of commands to check hardware information.
There are quite a few gui tools like hardinfo, sysinfo etc on the desktop, but having a generic command line tool is far more useful and this is where Inxi works well. Inxi is a set of scripts that will detect a whole lot of information about the hardware, including vendor details, device driver configuration etc. And most importantly, it will print everything in a easy to read format.
