from the man ln command

The ln utility creates a new directory entry (linked file) which has the same modes as the original file. It is useful for maintaining multiple copies of a file in many places at once without using up storage for the copies''; instead, a link points'' to the original copy. There are two types of links; hard links and symbolic links. How a link ``points'' to a file is one of the differences between a hard and symbolic link.

from the man launchctl command

launchctl interfaces with launchd to manage and inspect daemons, angents and XPC services.
