UNIX is a multi-tasking operating system built for computers. The UNIX system is used largely for aid in servers for businesses. The name UNIX is trademarked by a company called The Open Group, but there are many other software that work similar to the system, called “Unix system-like”. Currently, the version used in the movies is unknown to JPLegacy, but it is aware that it was a UNIX system or “Unix system-like”, from the quote used by Alexis Murphy, “it’s a Unix system, I know this.” It was used in the scene shortly after Lex and Tim narrowly escaped the Velociraptors in the kitchen, when Grant, Ellie, and the 2 kids were in the control room. Grant and Ellie tried to keep the door closed from the invading raptor, while Lex tried (and succeeded) to get the power back on.
