Linux File system Directories for DevOps Engineers.

Navigating Linux filesystems is crucial for effective DevOps practices. Understanding these directories helps manage systems and troubleshoot issues efficiently. Here’s a quick guide to key Linux directories.

/ (Root Filesystem): The root of the filesystem tree, containing everything needed to boot and run the system.

/boot: Stores static kernel and bootloader files necessary for system startup.

/bin: Contains essential user executables for basic system operations.

/dev: Provides access to device files representing hardware devices connected to the system.

/etc: Holds system configuration files crucial for system-wide settings.

/lib: Includes shared libraries needed to boot the system and run essential applications.

/home: The default directory for user files, with each user having their own subdirectory.

/mnt: A temporary mount point for filesystems during system maintenance or repair.

/media: Used for mounting external removable media like USB drives.

/opt: Contains optional application programs and vendor-specific software.

/root: The home directory for the root user, distinct from the root filesystem.

/tmp: Temporary storage for files used by the OS and applications, with files potentially being deleted without notice.

/sbin: System binaries used for administration tasks and system management.

/usr: Stores read-only files, including binaries, libraries, and documentation.

/var: Stores variable data like logs, databases, and web server files.
