Στο παρακάτω άρθρο εξηγείται απλά και κατανοητά (με παραδείγματα) η δομή του αγαπημένου μας λειτουργικού συστήματος. Προσωπικά, το βρήκα πολύ ενδιαφέρον καθώς έχω αναρωτηθεί πολλές φορές τι κάνουν όλοι αυτοί οι φάκελοι και γιατί είναι χωρισμένοι με αυτόν τον τρόπο.

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. /bin – User Binaries

    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. /sbin – System Binaries

    Just like /bin, /sbin also contains binary executables.
    But, the linux commands located under this directory are used typically by system aministrator, for system maintenance purpose.
    For example: iptables, reboot, fdisk, ifconfig, swapon

4. /etc – Configuration Files

    Contains configuration files required by all programs.
    This also contains startup and shutdown shell scripts used to start/stop individual programs.
    For example: /etc/resolv.conf, /etc/logrotate.conf

5. /dev – Device Files

    Contains device files.
    These include terminal devices, usb, or any device attached to the system.
    For example: /dev/tty1, /dev/usbmon0

6. /proc – Process Information

    Contains information about system process.
    This is a pseudo filesystem contains information about running process. For example: /proc/{pid} directory contains information about the process with that particular pid.
    This is a virtual filesystem with text information about system resources. For example: /proc/uptime

7. /var – Variable Files

    var stands for variable files.
    Content of the files that are expected to grow can be found under this directory.
    This includes — system log files (/var/log); packages and database files (/var/lib); emails (/var/mail); print queues (/var/spool); lock files (/var/lock); temp files needed across reboots (/var/tmp);

8. /tmp – Temporary Files

    Directory that contains temporary files created by system and users.
    Files under this directory are deleted when system is rebooted.

9. /usr – User Programs

    Contains binaries, libraries, documentation, and source-code for second level programs.
    /usr/bin contains binary files for user programs. If you can’t find a user binary under /bin, look under /usr/bin. For example: at, awk, cc, less, scp
    /usr/sbin contains binary files for system administrators. If you can’t find a system binary under /sbin, look under /usr/sbin. For example: atd, cron, sshd, useradd, userdel
    /usr/lib contains libraries for /usr/bin and /usr/sbin
    /usr/local contains users programs that you install from source. For example, when you install apache from source, it goes under /usr/local/apache2

10. /home – Home Directories

    Home directories for all users to store their personal files.
    For example: /home/john, /home/nikita

11. /boot – Boot Loader Files

    Contains boot loader related files.
    Kernel initrd, vmlinux, grub files are located under /boot
    For example: initrd.img-2.6.32-24-generic, vmlinuz-2.6.32-24-generic

12. /lib – System Libraries

    Contains library files that supports the binaries located under /bin and /sbin
    Library filenames are either ld* or lib*.so.*
    For example:,

13. /opt – Optional add-on Applications

    opt stands for optional.
    Contains add-on applications from individual vendors.
    add-on applications should be installed under either /opt/ or /opt/ sub-directory.

14. /mnt – Mount Directory

    Temporary mount directory where sysadmins can mount filesystems.

15. /media – Removable Media Devices

    Temporary mount directory for removable devices.
    For examples, /medica/cdrom for CD-ROM; /media/floppy for floppy drives; /media/cdrecorder for CD writer

16. /srv – Service Data

    srv stands for service.
    Contains server specific services related data.
    For example, /srv/cvs contains CVS related data.
