Difference Between Linux and UNIX

What is the difference between Linux and UNIX operating systems?

UNIX is a copyrighted name, and only big companies are allowed to use the UNIX copyright and name. For example, Apple macOS, IBM AIX, and Sun/Oracle Solaris and HP-UX all are UNIX operating systems. The Open Group holds the UNIX trademark in trust for the industry and manages the UNIX trademark licensing program. Let us see difference between Linux and UNIX OS in this quick tutorial.

ADVERTISEMENTS

Difference Between Linux and UNIX

Most UNIX systems are commercial in nature. You need to pay for support, software, training, and more. On the other hand, the Linux kernel is free to download and install on your systems free of cost.

Linux is a UNIX Clone

But if you consider Portable Operating System Interface (POSIX) standards, then Linux can be considered as UNIX. To quote from Official Linux kernel README file:

Linux is a Unix clone written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX compliance.

However, “Open Group” does not approve of the construction “Unix-like” and considers it a misuse of their UNIX trademark.

Linux is just a kernel

Linux is just a kernel. All Linux distributions includes GUI system + GNU utilities (such as cp, mv, ls,date, bash and more) + installation management tools + GNU c/c++ compilers + Editors (vi/ed/nano) + and various applications (such as OpenOffice, Firefox). However, most UNIX operating systems are considered as a complete operating system as everything come from a single source or vendor.

As I said earlier, Linux is just a kernel, and Linux distribution makes it complete usable operating systems by adding various applications. Most UNIX operating systems come with A-Z programs such as editor, compilers, and more. For example, HP-UX or Solaris comes with A-Z programs.

BSD family of operating systems

No discussion related to Unix is ever completed without discussing a free version of Unix. Typically all BSD family of operating systems are available free of cost and try to as close as possible to original Unix concepts. BSD family of operating systems based on BSD, the version of UNIX developed at the University of California, Berkeley. We have several operating systems that are based on BSD, including FreeBSD, OpenBSD, NetBSD, MidnightBSD, Darwin, and DragonFly BSD. Like Unix operating systems, the BSD family of an operating system typically comes with all required applications from a single project. An additional app/software can be installed using ports or binary package system.

License and cost

Linux is Free (as in beer [freedom]). You can download it from the Internet or redistribute it under GNU licenses. You will see the best community support for Linux. Most certified UNIX like operating systems are not free (but this is changing fast, for example, OpenSolaris UNIX). However, some Linux distributions such as Redhat (RHEL) / Novell (SUSE) provides additional Linux support, consultancy, bug fixing, and training for additional fees.

User-Friendly

Linux is considered as most user friendly UNIX-like operating systems. It makes it easy to install sound card, flash players, and other desktop goodies. However, macOS (Apple OS X) is most popular UNIX operating system for desktop and laptop users.

Security Firewall Software

Linux comes with open source netfilter/iptables/nftables based firewall tool to protect your server and desktop from the crackers and hackers. UNIX operating systems comes with its own firewall product (for example Solaris UNIX comes with ipfilter based firewall) or you need to purchase a 3rd party software such as Checkpoint UNIX firewall.

Backup and Recovery Software

UNIX and Linux comes with different set of tools for backing up data to tape and other backup media. However, both of them share some common tools such as tar, dump/restore, cpio and more.

File Systems

  • Linux by default supports and use ext3 or ext4 file systems.
  • UNIX comes with various file systems such as jfs, gpfs (AIX), jfs, gpfs (HP-UX), jfs, gpfs (Solaris), zfs and more.

System Administration Tools

  1. UNIX comes with its own tools such as SAM on HP-UX or smitty on IBM AIX.
  2. SUSE Linux comes with Yast/Yast2
  3. Red hat Linux comes with its own gui tools called redhat-config-*.

However, editing text config file and typing commands are most popular options for sysadmin work under Linux and Unix-like systems.

System Startup Scripts

Almost every version of UNIX and Linux comes with system initialization script but they are located in different directories:

  1. HP-UX – /sbin/init.d
  2. AIX – /etc/rc.d/init.d
  3. Linux – /etc/init.d. However, newer system uses systemd instead of /etc/init.d/ based script.

End User Perspective

The differences are not that big for the average end-user. They will use the same shell (e.g., BASH or KSH), text editors such as vim, and other development tools such as Perl, PHP, Python 3.x or Eclipse development tool.

System Administrator Perspective

Again, the differences are not that big for the system administrator. However, you may notice various differences while performing the following operations:

  1. Software installation procedure
  2. Hardware device names
  3. Various admin commands or utilities
  4. Software RAID devices and mirroring
  5. Logical volume management
  6. Package management
  7. Patch management

UNIX Operating System Names

A few popular names:

  1. HP-UX
  2. IBM AIX
  3. Sun Solaris (now Oracle Solaris)
  4. Apple Mac OS X (now macOS)
  5. IRIX

Linux Distribution (Operating System) Names

A few popular names:

  1. Red hat Enterprise Linux
  2. Fedora Linux
  3. Debian Linux
  4. Suse Enterprise Linux
  5. Ubuntu Linux
  6. Arch Linux
  7. Gentoo Linux

Common Things Between Linux and UNIX

Both share many common applications such as:

  1. GUI, file, and windows managers (KDE, Gnome)
  2. Shells (ksh, csh/tcsh, bash)
  3. Various office applications such as OpenOffice.org/libreoffice.org, and more
  4. Development tools (perl, php, python, ruby, GNU c/c++ compilers)
  5. Posix interface

UNIX and Linux Hardware

Commercial UNIX hardware has more advanced initial boot options such as:

  • Decide how to boot
  • Check system health
  • Set hardware parameters
  • Hard disk encrption and security

The BIOS that is standard in PCs which is used by Linux has few, of these features. UNIX hardware or servers are pretty expensive as compare to Linux server systems.

Unix Vs. Linux: Whats the Difference?

    Yes, you are absolutely correct. Free as in free beer means free of charge. Free as in speech indicates freedom to use, modify and redistribute as you wish, (freedom).

  • ajit kumar shukla Mar 7, 2009 @ 7:08

    Unix and linux both are multiuser operating system. Unix operating based on CUI(Character User Interface) and does not support pointing device, where as in linux opearating system; adding new features XWindows in Unix operating system and it is based on GUI(Graphical User Interface) i.e., it is like as DOS and Windows

      • hasini Jan 24, 2012 @ 11:50

        Linux has both GUI & CUI

        • hasini Jan 24, 2012 @ 11:51

          sorry that’s C L I (command line interface) not CUI

          • shiv prasad patel Jan 25, 2012 @ 18:20

            yes, linux is GUI (Graphical User Interface) and
            CLI( Command Line Interface)

            • tanmoy Mar 14, 2012 @ 4:40

              Linux has both CLI and GUI (via X window start it by cmd # startx) from cli;
              On the Other hand Unix is purely CLI, however many distribution has the GUI feature now. BSd unix for exmpl.

              • Ian Jan 26, 2017 @ 17:29

                I’m not sure where so much misinformation is coming from, but this bit about GUI vs CUI is just bunk. The X Window System including its use of mouse (“pointing device”) was developed on real UNIX systems 3/4 of a decade (1984 vs 1991) before Linux was even invented. All modern Unix systems support GUI as well as CLI interfaces, and have since before most of you were born. Please check on Wikipedia before blindly repeating false information.

      • vikram May 4, 2012 @ 10:19

        linux is GUI (graphical user intterface) and unix is CUI (charector user interface ) thats why it does not support pointing device…….

      • Bhargavi Jun 30, 2014 @ 17:50

        Linux supports both GUI and CLI

    • switch87 Sep 4, 2014 @ 18:20

      linux and unix ar standard cli. they both can run almost the same software, so the both suport gui. mac os is unix and has gui suport. most linux distributions have the possibility to use a bsd (=unix) kernel with the same gui you use with the linux kernel.

    Unix and linux both operating system is based in the multiuser/multing environment. and kernal
    based operating system. unix only suport the CUI but linux suport both CUI & GUI.
    basicaly this operating system is used in the network environment. it is very use full for security point of view.

  • Devasundaram Feb 27, 2010 @ 4:30

    • surya May 3, 2011 @ 15:09

      this is also a question that has to be raised… more over Linux LTS is for some 18 months to 3 yrs. what about after that. do we need to purchase Original OS Disks or any improvements.

      • vkc Aug 23, 2011 @ 20:39

        Linux LTS is supported for 18 months but you can use it indefinitely(or until the os becomes corrupt) which means no updates for software through internet

    UNIX is CUI……….But CUI means not character user interface………CUI means command user interface……….Unix is developed on C-language and C is a CUI which is Character user interface(CUI)…….so so many of us think that UNIX also Character user interface but its wrong……..UNIX is Command user interface……….

    please i need to know meaning of kernel

    • Kamal Kant Sharma Jul 12, 2011 @ 10:08

      Kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level.

      The kernel’s responsibilities include managing the system’s resources (the communication between hardware and software components).

  • Sisir Jul 29, 2011 @ 9:52

    The OS has basically 2 parts 1.Kernel 2.Shell ….. Kernel is the part which deals with the system resources and hardware and shell is the part which deals with the application software. Whenever any OS is designed first its Kernel is designed.The same had happened in case of Linux

    Wow…this is a load of FUD about UNIX. It has nothing to do with ONLY big companies.

    Instead UNIX is a trademark that signifies that the OS using it has passed specific tests and conforms the defined UNIX specification to handle interoperability. This is like POSIX which is also administered by The Open Group joinly with IEEE.

    Any OS can become UNIX-certified if the vendor chooses to try and can meet the standard. As far as I know, no Linux vendor (i.e. RedHat) has tried.

  • YEDU Jan 20, 2012 @ 4:37

  • Curious Feb 24, 2012 @ 10:17

    Can someone explain what “A-Z programs” are? If you google, the sentence
    “Most UNIX operating systems comes with A-Z programs such as editor, compilers etc.”
    is repeated verbatim all over the place, with no explanation. The next sentence won’t clarify much, either:
    “For example HP-UX or Solaris comes with A-Z programs.”
    Thanks!

    • 🐧 nixCraft Feb 24, 2012 @ 10:30

      Unix comes with all sort of utilities and command bundled from a single vendor such as IBM, HP, SUN/Oracle and so on. The single vendor provides you updates, patches, commands, installer, and management utilities (source #1).

      On other hand, Linux installs userland tools from GNU project (source #1). The installer scripts and management tools are often written by distro maintainers (source #2). Third party apps need to be downloaded and install as required (source #3). Also, you need to add additional repos to install binary software (such as EPEL or debian multimedia source #4).

      Hope this helps!

  • Taylor Sharpe Mar 16, 2012 @ 23:33

    It is interesting comparing screen shots of a bland Unix desktop compared to a nicely laid out Linux version. The Mac OS X is Unix certified and clearly has a very elegant and polished User Interface. The comparison between screen shots here implies that Linux desktops are more professional looking. In general that may be true, but not when comparing to the Mac. Being a Mac guy… just had to point that out.

    • Ash Sep 6, 2012 @ 9:35

  • messiVish Apr 10, 2013 @ 10:00

    So, Linux differs from UNIX by:
    -being operatable on PC’s
    -open source and therefore free

    UNIX obviously :
    – runs on mainframe computers only
    – and must be legally purchased as it is closed source

    is this corect?

    • kranthikumar Apr 26, 2017 @ 6:15

      BSD OS distributor is opensource, free and it is UNIX based

    so..linux and unix is a same thing? both compatible in a laptop or in cpu? means..when i want to change os from windows to ubuntu, i just uninstall windows or can the two os work together?

  • Ricky Jul 22, 2013 @ 15:16

    we can say linux as a flavor of unix.
    unix has its different versions for different companies

    • Ricky Jul 22, 2013 @ 15:20

      for example,
      IBM — AIX, HP — HP-UX, Sun — Solaris.
      same is for linux also…linux can available free to use but unix is not …
      different versions of linux has numbers of same applications but in unix different applications for different versions…

      thnks to all …its very good work …….keep it (y).!!!!!!!!!!!!

  • eagles051387 Jul 29, 2013 @ 10:06

    Hello,

    This is Hamid from Egypt, I am so interested to learn Unix. I found out that most of people in my country are tide up to Windows while I’ve had a quick look at Unix and I liked it so much. I am not asking you for any thing just to guide me to the right and true way to get the whole thing about it. Please tell me what to do to get it .

    With kindness always,
    Hamid Kamel

    Whenever i am searching about basics of unix, every other search comes up with basics of linux.
    is it because both of the are similar at base level? or am i missing something? since i have just started learning about unix, i am a bit confused whether leaning about one makes you understand the other then?

  • rusalika silas Jul 11, 2016 @ 16:47

    yes unix is part of lunix

  • Ian Jan 26, 2017 @ 17:32

    Article is seriously flawed by omitting discussion of modern Unix-derived open-source systems such as OpenBSD (the guys who gave you OpenSSH, the PF firewall and other innovations), FreeBSD and NetBSD, all derived from Berkeley Unix, a version developed at UC Berkeley in the late 1970’s.
