Files on a Linux system are organized into a single inverted tree of directories, a file-system hierarchy.

Absolute paths start with a forward slash character (/) and specify the location of a file in the file-system hierarchy.

Relative paths do not start with a forward slash character.

Relative paths specify a file location in relation to the current working directory.

You can use commands in combination with the dot (.), double dot (..), and tilde (~) special characters to refer to a file location in the file system.

The mkdir, rmdir, cp, mv, and rm commands are key commands to manage files in Linux.

Hard links and soft links are different ways for multiple file names to point to the same data.

The Bash shell provides pattern matching, expansion, and substitution features to help you to run commands efficiently.
