/boot: Stores the files necessary to start the Linux system.

/dev: Device files.

/etc: Configuration file.

/home: Stores the default working folder for all ordinary users.

/var: store some frequently changing files (such as the System log).

/usr: Store other user applications.

/media: Multimedia files.

/tmp: The temporary file used by the system to run the process.

/lib: Shared Library

These are just a few subdirectories that are commonly used in Linux.

Linux Command classification

Internal command: Some special instructions inside the Shell interpreter program, also called (built-in) directives.
