The racket command typically isn't a standard Linux command itself, but rather it refers to using the Racket programming language environment in a Linux environment. Racket is a dialect of Lisp that supports a variety of programming paradigms, including functional, object-oriented, and procedural styles. It features a powerful macro system, supports creating domain-specific languages, and offers a rich set of libraries. When 'racket' is mentioned, it generally implies invoking the Racket interpreter to execute Racket programs or using the Racket interactive environment (REPL).

To "run" a Racket program from the command line, you'd use the `racket` executable followed by the Racket source file. The Racket interpreter will then execute the code in that file. You can also invoke the Racket REPL by simply typing `racket` in the terminal without any arguments. This allows you to interactively execute Racket code line by line. Racket programs usually have a `.rkt` extension.

Typing `racket` without arguments will launch the Racket REPL. This is an interactive environment where you can enter Racket expressions and see their results immediately.

To execute a Racket program stored in a file (e.g., `myprogram.rkt`), use the command `racket myprogram.rkt`.
