What do you mean? A text file can't "utilize" JavaScript. It can contain JS code, but that's not executed unless the file is loaded into some other application. Also, it would be very difficult to identify such a thing.

Sorry, I think I misunderstood what you meant... You want to use JS to know how many lines are in the file, right?

If so, you can use the readFileIntoStream method of the util object and then parse it as a string to find that out.

One way would be to split it by new-line characters (either "\n" or "\r\n", depending on the encoding), and then check the length of the resulting array.

Thank you for you repsonse, I will look into what you have suggested. Is there a way to move to the beginning (first column) of the last line of the tab delimited file?
