New Command Advance Console Software for Hubby

My husband is now in the process of finishing his Computer degree. When he gets back from overseas he will enroll back in the nearest college or university. He was asking me to check out some software that has something to do with command prompt or command console for his upcoming programming class. I really don't have knowledge about it but I searched online and found this site, JP Software at jpsoft.com. I will let him know about it. I really don't understand how it works but hubby is a tech guy and its his passion. I bet he will be ecstatic about this new software.
