RunThrough

RunThrough["command",expr]

executes an external command, giving the printed form of expr as input and taking the output, reading it as Wolfram Language input, and returning the result.

Details

  • RunThrough writes the InputForm of expr on the standard input for command, then reads its standard output and feeds it into the Wolfram Language.
  • RunThrough starts command, gives input to command, then terminates the input.

Examples

Basic Examples  (1)

Run a Wolfram Language kernel in text mode, having it put a result in a temporary output file:

Wolfram Language code: mathcommand = StringReplace[First[$CommandLine], "WolframKernel" -> "wolfram"];
Wolfram Language code: outputfile = FileNameJoin[{$TemporaryDirectory, "rtout"}];
Wolfram Language code: RunThrough[mathcommand <> " -noprompt", Unevaluated[Put[Factorial[47], outputfile]]]

The result is now in the file:

Wolfram Language code: FilePrint[outputfile]

Delete the temporary file:

Wolfram Language code: DeleteFile[outputfile]
