@tmp is a completely separate variable that is not tied to the file. The split copies the data. You would have to add the following inside the foreach-loop to change the file as you intented:

$i= join(',',@tmp);

Note that even this works only because $i actually is an alias to the data in @lines and not a copy (this is magic done by the foreach loop)

    Thanks - when I think it through it makes sense as to why it wasn't writing to the file!

    Rejoining the value back into the line works perfectly!
