Overview of top-level directories

Now that we've got the basics of moving around using cd and listing directory contents using ls under control, let's start exploring other parts of the filesystem. Let's begin with an overview of every directory directly under the root filesystem, as specified by the FHS:

Location	Purpose
/bin/	Contains essential binaries (=tools) used by normal users
/boot/	Contains files used in the boot process: kernel, initramfs, bootloader
/dev/	Contains special files used to access devices
/etc/	Default location for software configuration files
/home/	Contains the home directories for normal users
/lib/	Contains system libraries
/lib64/	Contains 64bit system libraries ...
