The command "guile" refers to the GNU Guile programming language interpreter. GNU Guile is a programming language that is part of the GNU project and is based on the Scheme programming language. It provides a programming environment and a set of libraries for creating and running Scheme programs.
When you run the "guile" command in a terminal, it launches the Guile interpreter, which allows you to interactively execute Scheme code. It provides a read-eval-print loop (REPL) where you can input Scheme expressions, and it will evaluate and display the results.
For example, you can type simple expressions like (+ 2 3) and it will compute the sum and display the result, which in this case would be 5. You can also define functions, create variables, and perform various operations using the Scheme syntax.
In addition to being an interactive interpreter, Guile can also be used to run Scheme programs from files. You can provide a Scheme script as an argument to the "guile" command, and it will execute the code contained in that file.
Overall, the "guile" command allows you to use the GNU Guile programming language for writing and running Scheme programs interactively or from files.
