Is it a command one can use in Linux? Then it is a Linux command. And frankly I wouldn't put it past some people to have specialized peripherals they specifically use with Linux.
So Linux just annexes ownership of whatever it touches? Where does it end? You should code in Linux C++, using Linux emacs.And you can't get a Linux hardcopy without a Linux printer loaded with Linux ink and Linux paper. Don't forget your Linux ethernet cables and you need to have a handful of Linux thumb drives! And you'll be doing no Linux whatsoever without Linux electricity. ><
