What is the difference between Linux and Unix

Linux and Unix

Unix is popular operating system, developed by AT&T in 1969 and it has been very important to the development of the Internet. It is a multi-processing, multi-user, family of operating systems that run on a variety of architechtures. UNIX allows more than one user to access a computer system at the same time.

A widely used Open Source Unix-like operating system kernel. Linux was first released by its inventor Linus Torvalds in 1991. Combining the Linux kernel with the GNU software forms the basis of the operating system family generally known as \’Linux\’. There are distributions of GNU/Linux for almost every available type of computer hardware from desktop machines to IBM mainframes. The inner workings of GNU/Linux are open and available for anyone to examine and change as long as they make their changes available to the public, as set out in the terms of the GNU General Public License. Because of its robustness and availability, Linux has won popularity in the Open Source community as well as among commercial application developers.

Here is more input:

  • Unix requires a more powerful hardware configuration. It will work in large mainframe computers but will not work in an x86 based personal computer. Linux however, (which is built on the concept of Unix) has small hardware requirements and it will work on both a large mainframe computer and an x86 based personal computer.
  • Unix is an Operating System developed in olden days in which the kernel, the heart of the OS, interacts directly with the hardware. (note: this is the definition of what a kernel is). Because UNIX treats everything as a file, it provides greater security for users. An example of a UNIX distribution is posix. (note: actually POSIX is a set of standards for interoperability of applications between UNIX and UNIX-like systems). Linux uses a the UNIX architecture as its basis and provides more facilities and applications. Linux could be considered to be a GUI to the UNIX core. (note: this is plain wrong. GNU/ Linux was rewritten from scratch using UNIX as a guide. GNOME and KDE are GUIs for GNU/Linux). Examples of Linux distributions are Redhat, Fedora, Susee, Mandriva, and Ubuntu. Solaris OS also uses the UNIX kernal almost all UNIX commands will work on solaris in addition to 500 Solaris specific commands. (note: Solaris is also a rewrite of UNIX for x86, and does not use any original UNIX code). Both UNIX and LINUX are Open source. (note: UNIX is proprietary, Linux is open source)
  • Unix is the foundation for a number of operating systems, with Linux being the most popular one. Novell and Free BSD are 2 other commonly used Unix varients.(note: Again, the BSD family are based on another rewrite of UNIX for x86, UNIX is not their foundation in the sense implied here)
  • UNIX is an operating system created in the early days of computers. More recently, Linux was created as an open-source, freeware operating system. (note: Linux is free software, not freeware. Free software is open source that insists any developer reusing code releases their own work as free software. Freeware is proprietary software distributed at no cost [gratis]) It is \”UNIX-LIKE\”, meaning that it uses many UNIX constructs but also departs from traditional UNIX in many ways. Like UNIX, Linux is faster than many of the other commercially available operating systems. (note: This is a sweeping generalization and depends on the hardware used, and what servers and applications are running) It appears to also be far more robust than any of the Microsoft products. Linux is being used in many time critical applications because of it\’s speed. It is also used in many applications that need to maintain uptime because Linux, like UNIX, can run for months at a time without rebooting. While the typical method of solving Microsoft problems is to \”reboot\”, that particular requirement does not seem to be appropriate in a Linux/Unix environment. While UNIX has created a windows-like work environment, Linux has improved greatly on that concept. Linux has become a real player in the consumer operating system market… and it\’s free. While you may want to pay for a Linux distribution, the actual code is free and you are allowed to load it on as many machines as you want. You can get Linux for free if you wish to load it across the internet.


Unix :

A Operating System developed in olden days in which kernel interacts directly with the hardware.kernal is consider to be heart of this os.

In this Operating system everything is considered as a file,provides greater security.

Ex: posix

Linux :

Linux is an Operating system which use unix as its base and gives further more facilities and applications.

Merely speeking GUI is made in linux having unix as its core.

Ex: Redhat, Fedora, Susee, Mandrake . . .

Solaris OS also using the same unix kernal all the unix commands will work on solaris and have 500 more solaris specific commands. Differnent organizations used the UNIX kernal and added their own essence to form their own version of linux.

Both UNIX and LINUX are Open source by



yes, Unix most certainly can run on a \”smaller\” computer! BSD, a Unix, runs OK on a 486 (w/o graphical managers!) BSD is not Linux.(note: BSD is not UNIX either. Sorry)

Unix is portable: it can be on a Mainframe all the way to a cheap Wintelceleron-designed machine that you picked up at Walmart for under $200. (Just remove Windows). note: (if you mean unix-like, fine. UNIX itself can only run on mainframes and possibly minicomputers, not microcomputers (PCs))

There is only one reason left why Windows exists

156 minutes of pain compared with 26 minutes of success. That\’s the difference between a Windows installation and a Linux installation. After two and a half hours fiddling with a Windows install on my Toshiba laptop, it became pretty obvious what is one major reason why Windows remains a viable operating system.

Let me start by sharing a simple premise. I wanted a dual boot laptop, with Windows and Linux. Since Windows has an attitude problem it has to be on the primary partition and master drive to work correctly. No problem. I decided to simply start with a reinstall of Windows.

Bad idea. Reinstalling a base Windows to my laptop was going to be an event to end all installation events.

I am using a simple configuration on a Toshiba Satellite Pro 1GB RAM, 80GB 5400rpm disk, wifi, 10/100 and integrated video/sound run with Realtek. Straightforward stuff I thought.

rest here.


using gigolo for all your network mounting needs

Have you ever thought that there should be one central location or application to connect to all you required servers with whichever protocol. If you did, the you wishes are granted.

Name       : gigolo
Arch       : i686
Version    : 0.4.0
Release    : 1.fc12
Size       : 443 k
Repo       : installed
From repo  : updates
Summary    : GIO/GVFS management application
URL        : http://goodies.xfce.org/projects/applications/gigolo/
License    : GPLv2
Description: A frontend to easily manage connections to remote filesystems using GIO/GVFS.
           : It allows you to quickly connect/mount a remote filesystem and manage
           : bookmarks of such.

With gogolo you can mount FTP, WebDAV, obex, SSH, Windows Share(Samba) and others. You can use bookmarks too. What else do we need?
