PowerShell is superficially similar to Unix shells. PowerShell has aliases for many of the commands you are used to in Unix, like ls, rm, cp, mv, etc. However, the way that the cmdlets behind the aliases work is quite different.

Is PowerShell Linux based?

PowerShell is a configuration management tool that brings the capabilities of Linux command-line interface (CLI) control into the historically point-and-click Windows environment to manage Windows servers efficiently in virtual deployments.

Is PowerShell the same as Linux?

PowerShell makes use of pipes—just as Linux does—that allow you to pass the output of one cmdlet to the input of another cmdlet. Thus, you can use multiple cmdlets in sequence to manipulate the same data. Unlike Unix-like systems—which can only pipe streams of characters (text)—PowerShell pipes objects between cmdlets.
