The command "racket" refers to the Racket programming language and its corresponding interpreter or compiler. Racket is a general-purpose programming language that is known for its simplicity and ease of use. It provides a rich set of libraries and tools to facilitate the development of various types of applications.
When you run the "racket" command in your terminal or command prompt, it launches the Racket interpreter or compiler, depending on how the code is structured. It allows you to interactively execute Racket expressions, run Racket scripts, or even compile Racket programs into executable files.
For example, you can use the Racket interpreter to execute a single Racket expression like this:
$ racket
Welcome to Racket v7.9.
> (+ 2 3)
5
>
Here, the Racket interpreter starts, and you can enter Racket expressions interactively. In this case, the expression (+ 2 3)
is evaluated, and the result 5
is displayed.
Similarly, you can use the Racket command to run a Racket script saved in a file by providing the file's name as an argument:
$ racket my_script.rkt
This command executes the code present in the "my_script.rkt" file.
Overall, the "racket" command provides a way to work with the Racket programming language, allowing you to write, execute, and compile Racket code.
