Difference between Linux and Unix
Linux is an operating system developed in 1991 by Linus Torvalds. The name “Linux” originated from the Linux kernel. It is open-source, and the operating system is free to use. It is used for computer hardware and software, game development, mainframes, etc. It can run various client programs.
Unix is a portable, multi-tasking, a multi-user operating system developed by AT&T. It began as a one-person venture under the initiative of Ken Thompson of Bell Laboratories. It went on to become the most widely used operating system. It is used in web servers, workstations, and PCs. Many commercial applications are accessible in it.
|Linux is open-source, with many programmers working together online and contributing to its development.||Unix was developed by AT&T Labs, various commercial vendors, and non-profit organizations.|
|It is an open-source operating system that is freely accessible to all.||It is an operating system that only its copywriters can use.|
|It resolves any problem very quickly. Therefore, if a Linux client posts any threat, a team of qualified developers starts working to resolve this threat.||Unix requires a long time to get a bug.|
|It supports more file systems than Unix.||It supports fewer but file systems than Linux.|
|File system supports – Ext2, Ext3, Ext4, Jfs, ReiserFS, Xfs, Btrfs, FAT, FAT32, NTFS||File system supports – jfs, gpfs, hfs, hfs+, ufs, xfs, zfs|
|Linux provides two GUIs, KDE and Gnome. But there are many other options as well—for example, LXDE, Xfce, Unity, Mate, etc.||Initially, Unix was a command-based OS, although later, a GUI was called Common Desktop Environment. Most distributions now work with GNOME.|
|It is used everywhere from servers, PCs, smartphones, tablets to mainframes.||It is used in servers, workstations, and PCs.|
|The default interface is BASH (Born Again Shell).||It initially used the Bourne shell. But also compatible with other GUIs.|
|Anyone can use Linux, whether it is a home client, developer, or student.||It was developed primarily for servers, workstations, and mainframes.|
|The source is accessible to the general public.||The source is not accessible to the general public.|
|It was initially developed for Intel’s x86 hardware processor. It is available for over twenty different types of CPUs, including ARM.||It is available on PA-RISC and Itanium machines.|
|It has listed about 60–100 viruses so far.||It has about 85–120 viruses listed so far (rough estimates).|
|Some Linux versions are Ubuntu, Debian GNU, Arch Linux, etc.||Some UNIX versions are SunOS, Solaris, SCO UNIX, AIX, HP / UX, ULTRIX etc.|
- Linux is only the kernel and not the complete system used.
- More than 90% of the current Linux source code is composed by other developers.
- Initially, Linux was compiled using the GNU C Compile.
- More than 10 Linux-based mobile operating systems such as Sailfish OS, Ubuntu Touch, Ubuntu Mobile, etc.
- Every major space program uses Linux.
