Linux-Directory structure

excerpt from: http://www.comptechdoc.org/os/linux/usersguide/linux_ugfilestruct.html

This directory structure introduction is I currently see the most complete, there is time in translation.

Linux Directory Structure

Note:files is grouped according to purpose. Ex:commands, data files, documentation.

Parts of a Unix directory tree. See the FSSTND Standard (Filesystem)

/root|---rootthe home directory for the Root user|---homecontains the user ' s home directories|    |----ftpusers include many services as listed here|    |----httpd|    |----samba|    |----user1| |----user2|---bincommands needed during bootup that might being needed by normal users|---sbinlike bin but commands is not I  ntended for normal users. Commands run by linux.|  ---procthis filesystem is not on a disk.  Exists in the Kernels Imagination (virtual).    This directory| |    Holds information about kernel parameters and system configuration.|  |----1 A directory with info about process number 1.  Each process|has a directory below Proc.    |---usrcontains all commands, libraries, mans pages, games and static files for normal|    |operation.|  |----binalmost all user commands.    Some commands is In/bin or/usr/local/bin.|  |----Sbinsystem admin commands not needed on the root filesystem.    e.g., most servers |    |programs.|  |----includeheader files for the C programming language. ShOuld be Below/user/lib for|    |consistency.|    |----libunchanging data files for programs and subsystems|    |----localthe place for locally installed software and other files.|    |----manmanual pages|    |----Infoinfo documents|    |----docdocumentation for various packages|    |----tmp|  |----x11r6the X windows system files.    There is a directory similar to usr below this |    |directory.|  |----x386like X11R6 but for X11 release 5|---bootfiles used by the bootstrap loader, LILO. Kernel images is often kept here.|    ---libshared libraries needed by the programs on the root filesystem| |----Modules Loadable kernel modules, especially those needed to boot the system after| disasters.| ---devdevice files for devices such as disk drives, serial ports, etc.|    ---etcconfiguration files specific to the machine.|    |----Skelwhen A home directory is created it's initialized with files from this directory| |----Sysconfig Files that configure the Linux system for networking, KeyboarD, time, and more.|    ---varcontains files that change for mail, news, printers log files, man pages, temp files|    |----file|    |----Libfiles that change while the system is running normally|    |----localvariable data for programs installed in/usr/local.|  |----locklock files.    Used by a program to indicate it is using a particular device or file|    |----loglog files from programs such as login and syslog which logs all logins,|    |logouts, and other system messages.|    |----runfiles that contain information on the system that's valid until the system is|    |next booted|    |----spooldirectories for mail, printer spools, news and other spooled work.|    |----tmptemporary files that is large or need to exist for longer than they should in|    |/tmp.| |----Catmana cache for mans pages that is formatted on demand|---mntmount points for temporary mounts by the system Admini strator.|  ---tmptemporary files. Programs running after bootup should use/var/tmp.
