    NAME

    hier - Description of the file system hierarchy
     
    

    DESCRIPTION

    A typical Linux system has, among others, the following directories:
    /
    This is the root directory. This is where the whole tree starts.
    /bin
    This directory contains executable programs which are needed in single user mode and to bring the system up or repair it.
    /boot
    Contains static files for the boot loader. This directory only holds the files which are needed during the boot process. The map installer and configuration files should go to /sbin and /etc.
    /dev
    Special or device files, which refer to physical devices. See mknod(1).
    /etc
    Contains configuration files which are local to the machine. Some larger software packages, like X11, can have their own subdirectories below /etc. Site-wide configuration files may be placed here or in /usr/etc. Nevertheless, programs should always look for these files in /etc and you may have links for these files to /usr/etc.
    /etc/opt
    Host-specific configuration files for add-on applications installed in /opt.
    /etc/sgml
    This directory contains the configuration files for SGML and XML (optional).
    /etc/skel
    When a new user account is created, files from this directory are usually copied into the user's home directory.
    /etc/X11
    Configuration files for the X11 window system (optional).
    /home
    On machines with home directories for users, these are usually beneath this directory, directly or not. The structure of this directory depends on local administration decisions.
    /lib
    This directory should hold those shared libraries that are necessary to boot the system and to run the commands in the root file system.
    /media
    This directory contains mount points for removable media such as CD and DVD disks or USB sticks.
    /mnt
    This directory is a mount point for a temporarily mounted file system. In some distributions, /mnt contains subdirectories intended to be used as mount points for several temporary file systems.
    /opt
    This directory should contain add-on packages that contain static files.
    /proc
    This is a mount point for the proc file system, which provides information about running processes and the kernel. This pseudo-file system is described in more detail in proc(5).
    /root
    This directory is usually the home directory for the root user (optional).
    /sbin
    Like /bin, this directory holds commands needed to boot the system, but which are usually not executed by normal users.
    /tmp
    This directory contains temporary files which may be deleted with no notice, such as by a regular job or at system boot up.
    /usr
    This directory is usually mounted from a separate partition. It should hold only sharable, read-only data, so that it can be mounted by various machines running Linux.
    /usr/X11R6
    The X-Window system, version 11 release 6 (optional).
    /usr/X11R6/bin
    Binaries which belong to the X-Window system; often, there is a symbolic link from the more traditional /usr/bin/X11 to here.
    /usr/X11R6/lib
    Data files associated with the X-Window system.
    /usr/X11R6/lib/X11
    These contain miscellaneous files needed to run X; Often, there is a symbolic link from /usr/lib/X11 to this directory.
    /usr/X11R6/include/X11
    Contains include files needed for compiling programs using the X11 window system. Often, there is a symbolic link from /usr/include/X11 to this directory.
    /usr/bin
    This is the primary directory for executable programs. Most programs executed by normal users which are not needed for booting or for repairing the system and which are not installed locally should be placed in this directory.
    /usr/bin/X11
    is the traditional place to look for X11 executables; on Linux, it usually is a symbolic link to /usr/X11R6/bin.
    /usr/dict
    Replaced by /usr/share/dict.
    /usr/doc
    Replaced by /usr/share/doc.
    /usr/etc
    Site-wide configuration files to be shared between several machines may be stored in this directory. However, commands should always reference those files using the /etc directory. Links from files in /etc should point to the appropriate files in /usr/etc.
    /usr/games
    Binaries for games and educational programs (optional).
    /usr/include
    Include files for the C compiler.
    /usr/include/X11
    Include files for the C compiler and the X-Window system. This is usually a symbolic link to /usr/X11R6/include/X11.
    /usr/include/asm
    Include files which declare some assembler functions. This used to be a symbolic link to /usr/src/linux/include/asm.
    /usr/include/linux
    This contains information which may change from system release to system release and used to be a symbolic link to /usr/src/linux/include/linux to get at operating system specific information.

    (Note that one should have include files there that work correctly with the current libc and in user space. However, Linux kernel source is not designed to be used with user programs and does not know anything about the libc you are using. It is very likely that things will break if you let /usr/include/asm and /usr/include/linux point at a random kernel tree. Debian systems don't do this and use headers from a known good kernel version, provided in the libc*-dev package.)

    /usr/include/g++
    Include files to use with the GNU C++ compiler.
    /usr/lib
    Object libraries, including dynamic libraries, plus some executables which usually are not invoked directly. More complicated programs may have whole subdirectories there.
    /usr/lib/X11
    The usual place for data files associated with X programs, and configuration files for the X system itself. On Linux, it usually is a symbolic link to /usr/X11R6/lib/X11.
    /usr/lib/gcc-lib
    contains executables and include files for the GNU C compiler, gcc(1).
    /usr/lib/groff
    Files for the GNU groff document formatting system.
    /usr/lib/uucp
    Files for uucp(1).
    /usr/local
    This is where programs which are local to the site typically go.
    /usr/local/bin
    Binaries for programs local to the site.
    /usr/local/doc
    Local documentation.
    /usr/local/etc
    Configuration files associated with locally installed programs.
    /usr/local/games
    Binaries for locally installed games.
    /usr/local/lib
    Files associated with locally installed programs.
    /usr/local/include
    Header files for the local C compiler.
    /usr/local/info
    Info pages associated with locally installed programs.
    /usr/local/man
    Man pages associated with locally installed programs.
    /usr/local/sbin
    Locally installed programs for system administration.
    /usr/local/share
    Local application data that can be shared among different architectures of the same OS.
    /usr/local/src
    Source code for locally installed software.
    /usr/man
    Replaced by /usr/share/man.
    /usr/sbin
    This directory contains program binaries for system administration which are not essential for the boot process, for mounting /usr, or for system repair.
    /usr/share
    This directory contains subdirectories with specific application data, that can be shared among different architectures of the same OS. Often one finds stuff here that used to live in /usr/doc or /usr/lib or /usr/man.
    /usr/share/dict
    Contains the word lists used by spell checkers.
    /usr/share/doc
    Documentation about installed programs.
    /usr/share/games
    Static data files for games in /usr/games.
    /usr/share/info
    Info pages go here.
    /usr/share/locale
    Locale information goes here.
    /usr/share/man
    Manual pages go here in subdirectories according to the man page sections.
    /usr/share/man/<locale>/man[1-9]
    These directories contain manual pages for the specific locale in source code form. Systems which use a unique language and code set for all manual pages may omit the <locale> substring.
    /usr/share/misc
    Miscellaneous data that can be shared among different architectures of the same OS.
    /usr/share/nls
    The message catalogs for native language support go here.
    /usr/share/sgml

    /usr/share/tmac
    Troff macros that are not distributed with groff.
    /usr/share/zoneinfo
    Files for timezone information.
    /usr/src
    Source files for different parts of the system, included with some packages for reference purposes. Don't work here with your own projects, as files below /usr should be read-only except when installing software.
    /usr/src/linux
    This was the traditional place for the kernel source. Some distributions put here the source for the default kernel they ship. You should probably use another directory when building your own kernel.
    /usr/tmp
    Obsolete. This should be a link to /var/tmp. This link is present only for compatibility reasons and shouldn't be used.
    /var
    This directory contains files which may change in size, such as spool and log files.
    /var/adm
    This directory is superseded by /var/log and should be a symbolic link to /var/log.
    /var/backups
    Reserved for historical reasons.
    /var/cache
    Data cached for programs.
    /var/catman/cat[1-9] or /var/cache/man/cat[1-9]
    These directories contain preformatted manual pages according to their man page section. (The use of preformatted manual pages is deprecated.)
    /var/cron
    Reserved for historical reasons.
    /var/lib
    Variable state information for programs.
    /var/local
    Variable data for /usr/local.
    /var/lock
    Lock files are placed in this directory. The naming convention for device lock files is LCK..<device> where <device> is the device's name in the file system. The format used is that of HDU UUCP lock files, that is, lock files contain a PID as a 10-byte ASCII decimal number, followed by a newline character.
    /var/log
    Miscellaneous log files.
    /var/opt
    Variable data for /opt.
    /var/mail
    Users' mailboxes. Replaces /var/spool/mail.
    /var/msgs
    Reserved for historical reasons.
    /var/preserve
    Reserved for historical reasons.
    /var/run
    Run-time variable files, like files holding process identifiers (PIDs) and logged user information (utmp). Files in this directory are usually cleared when the system boots.
    /var/spool
    Spooled (or queued) files for various programs.
    /var/spool/at
    Spooled jobs for at(1).
    /var/spool/cron
