Linux File Structure

  • All Directories are in Hierarchical structure or tree structure
  • Topmost directory is "/" which is called slash or root.
A typical linux structure will look like this
 /boot       This is where the Linux kernel is kept. It is a file called vmlinuz, this is also the version of the OS installed.

/bin          This contains files that are essential for normal operation of the system. These are available for use by all users.

/dev          This contains the information for all the devices such as hard disk, CD-ROM drive, etc.

/etc          Various system configuration files are stored in this location.

/home       This is where the users have their home directory. Similar to Documents and settings in Windows

/lib           The shared libraries (similar to DLLs in Windows) are kept here.
/lib64
