Well there is a big library of them called the internet......
There are two series of books on many computing subjects that are well worth buying.
????? for Dummies actually is quite broad spectrum. It is light hearted, but delves deeply. https://www.google.co.uk/search?as_q...os+for+dummies
An Idiot's Guide to ?????? is very similar. https://www.google.co.uk/search?as_q...t+guide+to+dos
Those are for DOS which is the basis of the command prompts. The Command Prompts may have OS specific commands and will be a subset of full DOS
