$ man file-hierarchy
DESCRIPTION
file-hierarchy is a systemd documentation page (man page) describing the file system hierarchy used by systemd-based Linux systems. It documents the purpose of directories under /, /etc, /usr, /var, and other key locations.
This is not an executable command but a reference document explaining where files should be placed and why.
