Linux Directory Structure (File System Structure) Explained with Examples

Linux Directory Structure (File System Structure) Explained with Examples
by Ramesh Natarajan on September 8, 2010 Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin? For example, less command is located under /usr/bin directory. Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories? In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory.Only root user has write privilege under this directory.Please note that /root is root user’s home directory, which is not same as /. 2. Contains binary executables.Common linux commands you need to use in single-user modes are located under this directory.Commands used by all the users of the system are located here.For example: ps, ls, ping, grep, cp. 3. 4. 5. Contains device files.These include terminal devices, usb, or any device attached to the system.For example: /dev/tty1, /dev/usbmon0 6. 7. 8. 9.

Linux Newbie Guide by Stan, Peter and Marie Klimas Intro. We are relative Linux newbies (with Linux since Summer 1998). We run mostly RedHat and Mandrake -> the solutions might not be directly applicable to other Linux distributions (although most of them probably will be). Hope this helps; we try to be as practical as possible. Unix filesystem "Unix file system" redirects here. For UFS, a specific file system used by many Unix and Unix-like operating systems, see Unix File System. In Unix and operating systems inspired by it, the file system is considered a central component of the operating system.[1] It was also one of the first parts of the system to be designed and implemented by Ken Thompson in 1969.[2]

32 Best Linux Desktop Customization #4 Voici la quatrième édition des meilleures personnalisations de bureaux Linux. Six mois se sont écoulés depuis la dernière présentation, les tendances n'ont pas beaucoup évolué, sauf peut-être que l'on voit de plus en plus de customizations à base de KDE (cf. 6 derniers screenshots). Je vous laisse les découvrir sans plus attendre. Gaia10 Linux by Gabriela2400

Learning the shell. Why do you need to learn the command line anyway? Well, let me tell you a story. Not long ago we had a problem where I used to work. Time dilation Time dilation explains why two working clocks will report different times after different accelerations. For example, ISS astronauts return from missions having aged slightly less than they would have been if they had remained on Earth, and GPS satellites work because they adjust for similar bending of spacetime to coordinate with systems on Earth.[1] An accurate clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's own equally accurate clocks. This effect arises neither from technical aspects of the clocks nor from the fact that signals need time to propagate, but from the nature of spacetime itself. Overview[edit] In theory, and to make a clearer example, time dilation could affect planned meetings for astronauts with advanced technologies and greater travel speeds.

Highly useful Linux commands & configurations Update, August 2010: A few broken links fixed; thank you, George! Update, September 2008: A few errors corrected; thank you, Umarzuki! Oh, you're gonna love this article! Even though there are many websites hawking similar content, with varying degree of clarity and quality, I want to offer a short, easy-to-use guide to some of the most common yet highly useful commands that could help make your Linux experience more joyful. Filesystem Hierarchy Standard The Filesystem Hierarchy Standard (FHS) defines the directory structure and directory contents in Unix[citation needed] and Unix-like operating systems, maintained by the Linux Foundation. The current version is 3.0, released on 18 May 2015.[1] Directory structure[edit] The majority of these directories exist in all UNIX operating systems and are generally used in much the same way; however, the descriptions here are those used specifically for the FHS, and are not considered authoritative for platforms other than Linux. FHS compliance[edit] Most Linux distributions follow the Filesystem Hierarchy Standard and declare it their own policy to maintain FHS compliance.[9][10][11][12] GoboLinux is an example of an intentionally non-compliant filesystem implementation.[13]

Best Linux Software Advertisement You’ve made the switch from Windows or Mac OS X, and now you’re looking for applications to install.

Lackadaisy Expressions Boy, I didn't know what I was getting myself into when I started this. I've had requests for some sort of expressions tutorial dating back a while now, so I figured, "Sure! I can explain expression drawing...and it'll be way better than all those tutorials out there that are nothing but charts of generic expressions.
