Learning Salesforce DX, have downloaded the DreamHouse project from gitHub site, made a new branch of my own.  Then, in the Unit of "Create and Test Our Scratch Org", at the beginning, it says "Enter cat config/project-scratch-def.json" to see some of the options available. When I did this in the command line, I got "cat not recognized as an internal or external command".  Online articles say that "cat" is a Unix code, can't be used in Windows system.  Now, my question is what should I use in Windows?

Thanks!
