I have the following to execute shell commands using Node:

function puts( error, stdout, stderr ) {
    stdout = sanitize( stdout ).rtrim("\n"); // remove new line
    sys.puts( stdout );
}

I use this library to try and Remove new lines:

npm install validator

but when I do something like this:

exec( "ls -l", puts );

it puts a new line character on the end.

I'm using Linux so the new line should just be a \n right?!

How do I stop the new line from happening?

Many thanks.

Are you sure that the call to sys.puts isn't what's adding the newline? Try sys.print and see what you get.

In other news, I think that sys.puts (and sys in general) have been deprecated in node.js for a while. You should probably use console.log for this kind of thing.
