Is Windows Unix like?
Aside from Microsoft’s Windows NT-based operating systems, nearly everything else traces its heritage back to Unix.

What are the types of Unix?
The seven standard Unix file types are regular, directory, symbolic link, FIFO special, block special, character special, and socket as defined by POSIX. Different OS-specific implementations allow more types than what POSIX requires (e.g. Solaris doors).
Is Unix operating system free?
