Welcome to the Unix & Linux Forums.
Unix (all-caps for the UNIX trademark) is multitasking, multiuser computer operating system environment from the original AT&T Unix developed at Bell Labs research center by Ken Thompson, Dennis Ritchie, and others in the 1970s. Linux is a Unix-like and mostly POSIX-compliant computer operating system designed as a free and open-source software development and distribution environment first released on 5 October 1991 by Linus Torvalds. unix.com is a free technical support community for all unix, unix-like and linux operating systems.
