Difference between Linux text mode and Windows command prompt

Question

I don't know if this is a dumb question or not but again as my professor says if you have doubts then clear them . What is the difference between Linux text mode and windows command prompt (cmd). I know both windows and Linux are different Operating Systems but when you look at the commands, some of the commands are common For Example cd command.

Answer 1

Although superficially similar in some ways, the two command line interfaces have different lineages:

• The Windows command prompt is based heavily on that of MS-DOS / PC-DOS, which in turn was based on the CP/M Console Command Processor. The CP/M CCP interface was itself based on an earlier operating system called RSTS.

• The Linux shells trace their roots back to the original UNIX Thompson shell; the Thompson shell borrowed from the Multics shell (where the term "shell" originated).

Traces of these are still evident today - the DIR command in the Windows command prompt can be traced all the way back to the DIR command in RSTS, and similarly the ls command in GNU coreutils can be traced back to the Multics "list segments" command.

Answer 2

They're both based on the same idea and are called Command-Line Interfaces (see wikipedia). They operate off the same principals, just using different keywords to perform similar commands. It should be noted however, that the commands although similarly named, may not perform the exact same function. They are just abstractions of lower level functions of the operating system. Just like people can explain similar ideas using different words and phrases, the same applies in this situation. For reference here's a list of Bash commands: http://ss64.com/bash/ and the same website has windows commands.
