Check out C#. CliWrap does exactly this: https://github.com/Tyrrrz/CliWrap/blob/master/CliWrap/Comman...

    // Examples
    var cmd = Cli.Wrap("foo") | (stdOut, stdErr);

    var target = PipeTarget.Merge(
        PipeTarget.ToFile("file1.txt"),
        PipeTarget.ToFile("file2.txt"),
        PipeTarget.ToFile("file3.txt")
    );

    var cmd = Cli.Wrap("foo") | target;
