Understanding Directory Hierarchy

In Linux, understanding the directory hierarchy is crucial for efficient navigation and file management. A Linux system's directory structure, also known as the Filesystem Hierarchy Standard (FHS), is a defined tree structure that helps to prevent files from being scattered all over the system and instead organise them in a logical and easy-to-navigate manner.

  • /: Root directory, the top level of the file system.
  • /home: User home directories.
  • /bin: Essential binary executables.
  • /sbin: System administration binaries.
  • /etc: Configuration files.
  • /var: Variable data (logs, spool files).
  • /usr: User programs and data.
  • /lib: Shared libraries.
  • /tmp: Temporary files.
