Difference Between Linux and UNIX

What is the difference between Linux and UNIX operating systems?

UNIX is copyrighted name only big companies are allowed to use the UNIX copyright and name, so IBM AIX and Sun 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.

Most UNIX systems are commercial in nature.

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" do not approve of the construction "Unix-like", and consider it 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 etc) + installation & management tools + GNU c/c++ Compilers + Editors (vi) + 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 comes with A-Z programs such as editor, compilers etc. For example HP-UX or Solaris comes with A-Z programs.

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 UNIX like operating systems are not free (but this is changing fast, for example OpenSolaris UNIX). However, some Linux distributions such as Redhat / Novell 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, Apple OS X is most popular UNIX operating system for desktop usage.

Security Firewall Software

Linux comes with open source netfilter/iptables 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, and cpio etc.

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).

System Administration Tools

  1. UNIX comes with its own tools such as SAM on HP-UX.
  2. Suse Linux comes with Yast
  3. Redhat Linux comes with its own gui tools called redhat-config-*.

However, editing text config file and typing commands are most popular options for sys admin work under UNIX and Linux.

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

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) and other development tools such as Perl 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 Solairs
  4. Mac OS X
  5. IRIX

Linux Distribution (Operating System) Names

A few popular names:

  1. Redhat Enterprise Linux
  2. Fedora Linux
  3. Debian Linux
  4. Suse Enterprise Linux
  5. Ubuntu Linux

Common Things Between Linux & UNIX

Both share many common applications such as:

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

A Sample UNIX Desktop Screenshot

A Sample Linux Desktop Screenshot

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 etc

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 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

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.

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.

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

158 Kamal Kant Sharma July 12, 2011 at 10:08 am

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).

Reply

159 Sisir July 29, 2011 at 9:52 am

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.

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!

191 nixCraft February 24, 2012 at 10:30 am

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!

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.
