Pipe stuff into stdin of the first command.

Like:

var jsHell = jshell('grep', 'foo');
someGiantLogFileStream.pipe(jsHell.stdin);

jsHell.pipe('grep', 'bar');

It would work if jshell is a writable stream.

I think this looks cleaner and reads better:

var jsHell = jshell();

someGiantLogFileStream.pipe(jsHell.stdin);

jsHell.pipe('grep', 'foo');
jsHell.pipe('grep', 'bar');

But it's shouldn't make a difference.

I agree, but I think it should be like this:

someGiantLogFileStream.pipe(jshell('grep', 'foo').pipe('grep', 'bar')).log();
