This 948 page PDF is an excellent technical resource, as highlighted below by SANS ISC

Use this PDF to find the documentation resources and other technical information that you need to learn about the command shell, and to automate command-line tasks by using scripts or scripting tools.  This is 948 pages of Windows raw command-line power, for blue and red teams, for sysadmins and users; if you use Windows, this is an imperative download and a must-have reference guide. I am reasonably certain even the most knowledgeable among you will find a command or two you weren’t aware of. You will find this PDF useful and easy to navigate, may I humbly suggest you download and incorporate it into your reference library.
