You want to be able to view information about a system from a linux shell in terms of what disks it has, what processor, the system model the vendor etc.
There is a program in linux called dmidecode which pulls this information straight from the systems BIOS.
You can run dmidecode by simply typing "dmidecode" in a linux shell. However it spits out a lot of information so I recommend running it through "more" or "less".
dmidecode | more
dmidecode | less
You can then scroll through this information and find out all kinds of cool information about the system such as what model it is!
