Linux Directory Hierarchy

Filesystem structure

The Linux Directory Hierarchy is a fundamental organizational framework that underpins the entire Linux operating system. However, It serves as the backbone for file storage, management, and navigation, enabling users and system processes to efficiently locate and interact with files and directories. NonethelessThe Linux Directory Hierarchy encompasses a structured arrangement of directories, each serving a specific purpose, which collectively contributes to the seamless functioning of the OS.

Understanding the intricacies of the Linux Directory Hierarchy is crucial for both beginners and experienced users, as it dictates the pathways through which various system components communicate and operate. From the root directory onward, every level of the hierarchy plays a significant role in maintaining order and facilitating tasks such as software installation, system configuration, user management, and data storage.

Unveiling the Layers and Significance of Linux Directory Hierarchy

This introductory exploration into the Linux Directory Hierarchy will unravel its layers, functionalities, and significance. Moreover, it will also Empowering users to navigate and harness the potential of the Linux ecosystem effectively.

Here is the essential information you need to become familiar with while learning Linux.

/bin – Binaries.
/boot – Files required for booting.
/dev – Device files.
/etc – Etcctera. Furthermore, The name originates from the earliest Unixes and became the designated location for configuration files.
/home – Keep home directories here
/lib – Code libraries reside where programmers store them for easy access and utilization.
/media – Mount removable media on a contemporary directory for a more modern approach.
/mnt – Mount temporary file-systems at the specified location.
/opt – Optional add-on software is installed where applicable.
This is discrete from /usr/local/ for reasons I’ll get to later.
/run – Where runtime variable data is kept.
/sbin – Where super-binaries are stores.
These usually only work with root.
/usr – Another directory inherited from the Unixes of old, it stands for “user”.
Share this directory among hosts, and safely NFS mount it to multiple hosts. You can safely mount it as read-only.

Managing Dynamic System Data: Exploring the /var Directory in Linux

/var – Another directory inherited from the Unixes of old, it stands for “variable”. Store varying system data here.
However, Such things as spool and cache directories may be located here.
If a program needs to write to the local file-system and isn’t serving that data to someone directly,
it’ll go here.
/srv – Stands for “serve”. This directory is intended
for static files that are served out.
/srv/http would be for static websites,
/srv/ftp for an FTP server.

/opt stands for optional (as in optional add-on packages).
/bin stands for binary (contains executables used by the OS).
/lib stands for library (contains shared libraries used by filesystem and for booting, probably used by the executables in bin)
/proc stands for processes.
/root means root user.
/home holds the home sub-directories for any non-root users.
/dev stands for device (holds special and device files).
/tmp stands for temporary.
/srv stands for serve.
/mnt stands for mount point (mount a temporary filesystem here).
/include contains #include files, i.e. header files (e.g., stdio.h).
/var stands for variable
/etc stands for etcetera

For more data on the layout of Linux file-systems, look at the Filesystem Hierarchy Standard (now at version 2.3, with the beta 3.0 version deployed on most recent distros). It does explain some of where the names came from.
