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.
