What is Unix? Unix VS Linux
What is Unix?
Unix is a multi-tasking, multi-user operating system but is not free to use and is not open source. It is widely used on servers, workstations, etc. The Unix operating system is a set of programs that act as a link between the computer and the user. The computer programs that allocate the system resources and coordinate all the details of the computer’s internals are called the operating system or the kernel. Users communicate with the kernel through a program known as the shell. The shell is a command-line interpreter; it translates commands entered by the user and converts them into a language that is understood by the kernel. There are various Unix variants available in the market. Solaris Unix, AIX, HP Unix, and BSD are a few examples. Linux is also a flavor of Unix which is freely available. Several people can use a Unix computer at the same time; hence Unix is called a multiuser system. A user can also run multiple programs at the same time; hence Unix is a multitasking environment.
Unix vs Linux
Definition
Linux is It is an open-source operating system that is freely available to everyone. While It is an operating system that can be only used by its copyrighters.
Examples
It has different distros like Ubuntu, Redhat, Fedora, etc
IBM AIX, HP-UX and Sun Solaris.
Users
Nowadays, Linux is in great demand. Anyone can use Linux whether a home user, developer, or student.
It was developed mainly for servers, workstations, and mainframes.
Usage
Linux is used everywhere from servers, PC, smartphones, tablets to mainframes and supercomputers.
It is used in servers, workstations, and PCs.
Cost
Linux is freely distributed, downloaded, and distributed through magazines also. And priced distros of Linux are also cheaper than Windows.
Unix copyright vendors decide different costs for their respective Unix Operating systems.
Development
As it is open-source, it is developed by sharing and collaboration of codes by worldwide developers.
Unix was developed by AT&T Labs, various commercial vendors, and non-profit organizations.
Manufacturer
Linux kernel is developed by a community of developers from different parts of the world. Although the father of Linux, Linus Torvalds oversees things.
Unix has three distributions IBM AIX, HP-UX, and Sun Solaris. Apple also uses Unix to make OSX operating system.
GUI
Linux is a command based but some distros provide GUI-based Linux. Gnome and KDE are mostly used GUI.
Initially, it was a command-based OS, but later Common Desktop Environment was created. Most Unix distributions use Gnome.
Interface
The default interface is BASH (Bourne Again Shell). But some distros have developed their own interfaces.

File support system
Linux supports more file systems than Unix. It also supports a file system but lesser than Linux.
Coding
Linux is a Unix clone, behaves like Unix but doesn’t contain its code.
Unix contains a completely different coding developed by AT&T Labs.
Operating system
Linux is just the kernel.
Unix is a complete package of Operating systems.
Security
It provides higher security. Linux has about 60–100 viruses listed to date.
Unix is also highly secured. It has about 85–120 viruses listed to date
Error detection
As Linux is open-source, whenever a user posts any kind of threat, developers from all over the world start working on it. And hence, it provides a faster solution.
In Unix, users have to wait for some time for the problem to be resolved.
Target Processors:
Linux was initially developed for Intel’s x86 hardware processors. Now it supports 20+ processor families. Unix supports PA-RISC and Itanium families.
