When i use these commands on cmd of Windows 7, they are all unrecognized (except cd and ls). Why is that?


For ex - touch kr.txt does not generate a new file in my current directory, instead it shows the error 'touch' is not recognized as an internal or external command, operable program or batch file. Also, i don not see '$' written anywhere in my cmd and if i use it explicitly with any command it throws the same error '$' is not recognized...


The commands in this course are not for windows operating system.

I don't know if it will work with all the commands but maybe try using PowerShell instead? I use it when I need to do command like stuff with Python and it seems to work with most Linux commands :smile:

Go to the Start Menu and type powershell, it should be on your pc already I think.
