Below I am mentioning some differences between Linux and Unix.
Linux has both free and paid version but Unix has only paid free version not available in free.
Linux source code is available to the general public whereas, in Unix, the source code is proprietary.
Linux user by general user, developer, .etc. But Unix mainly uses in internet server, Workstation server, .etc.
UNIX OS was created in the late 1960s at AT&T Bell Labs whereas Linux is an operating system built by Linus Torvalds at the University of Helsinki in 1991.
Linux is a clone of Unix.
Linux default shell is BASH while the Unix shell is Bourne Shell.
Linux threat detection and solution are very fast while Unix users require longer wait times to get the proper bug fixing patch.
Important versions of Linux are Redhat, Ubuntu, OpenSuse, Solaris, whereas important versions of Unix are HP-UX, AIS, BSD, etc.
