Linux File Structure

Linux File Structure

• root - The home directory for the root user
• home - Contains the user's home directories
• bin - Commands needed during bootup that might be needed by normal users
• sbin - Like bin but commands are not intended for normal users. Commands run by LINUX.
• proc - This filesystem is not on a disk. It is a virtual filesystem that exists in the kernels imagination which is memory.
  
  
  • 1 - A directory with info about process number 1. Each process has a directory below proc.
• usr - Contains all commands, libraries, man pages, games and static files for normal operation.
  
  
  • bin - Almost all user commands. some commands are in /bin or /usr/local/bin.
  • sbin - System admin commands not needed on the root filesystem. e.g., most server programs.
  • include - Header files for the C programming language. Should be below /user/lib for consistency.
  • lib - Unchanging data files for programs and subsystems
  • local - The place for locally installed software and other files.
  • man - Manual pages
  • info - Info documents
  • doc - Documentation
  • X11 - The X windows system files.
• boot - Files used by the bootstrap loader, LILO. Kernel images are often kept here.
• lib - Shared libraries needed by the programs on the root filesystem
  
  
  • modules - Loadable kernel modules, especially those needed to boot the system after disasters.
• dev - Device files
• etc - Configuration files specific to the machine.
  
  
  • skel - When a home directory is created it is initialized with files from this directory
  • sysconfig - Files that configure the linux system for devices.
• var - Contains files that change for mail, news, printers log files, man pages, temp files
  
  
  • lib - Files that change while the system is running normally
  • local - Variable data for programs installed in /usr/local.
  • lock - Lock files. Used by a program to indicate it is using a particular device or file
  • log - Log files from programs such as login and syslog which logs all logins and logouts.
  • run - Files that contain information about the system that is valid until the system is next booted
  • spool - Directories for mail, printer spools, news and other spooled work.
  • tmp - Temporary files that are large or need to exist for longer than they should in /tmp.
• mnt - Mount points for temporary mounts by the system administrator.
• tmp - Temporary files.
