scheme: Run a scheme program (with no REPL output).
$ scheme --quiet < ${script-scm}
try on your machine
This command is invoking the "scheme" interpreter with the "--quiet" option.
The "--quiet" option means that the interpreter will not display any startup messages or information while executing the provided script.
The input redirection "<" is used to redirect the contents of the file named "${script-scm}" as input to the "scheme" interpreter. The "${script-scm}" is a placeholder for the actual file name or path of the script to be executed.
In summary, this command is executing a script file using the "scheme" interpreter, suppressing any startup messages or information. The content of the script is read from the file specified by "${script-scm}".
