What should I search to better understand what is written here? Don't mind learning myself, just looking for the correct keywords. Thanks!

Read the Bash manual. That one patter on the GP is called "Command Substitution", you can search for it.

This comment is a joke and you wouldn't want to do it like that in reality, but here are some related keywords you could look up: "Unix cat", "Unix pipeline", "grep", "output redirection", "command substitution".
