Difference between Linux text mode and Windows command prompt
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 a开发者_开发百科re common For Example cd command
.
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.
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.
The difference is the operating system. The command prompt (cmd) and a terminal emulator (linux bash shell or similar) are text interfaces to the operating system. They allow you to manipulate the file system and run programs without the graphical interface.
You should read about Linux shells. The Bash shell for instance, is among the most used Linux shells... ever!

And if you're looking for a list of commands: http://www.physics.ubc.ca/mbelab/computer/linux-intro/html/
It is not that commands are in common (well yes, maybe some), it is that they have the same name and do almost the same things, as for cd
as you said.
The shells are an abstraction of the underlying operative system, Linux and Windows have a different kernel, hence the difference.
