Since you don't show us any real example of what your file looks like we are left to guesses. Therefore the following is again - a guess (btw.: my code worked perfectly on AIX, Solaris and Ubuntu Linux - more Unix/Linux dialects i don't have at hand but probably nothing will change the result).

Files are different in Windows/DOS and UNIX. The reason is that newlines are encoded differently. In UNIX dialects a newline is encoded in a single character, a "^M" (control-m), the linefeed character. In DOS/Windows a newline is encoded in two characters, a CR (carriage return) and a LF (line feed).

Create a file under UNIX (issue "cat > unixfile", then start typing, press "control-D" to end the input) and get a file created under Windows. Now issue "od -ax dosfile | more" and "od -ax unixfile | more" in two windows and observe the difference.

If this is the case with your file try "ASCII mode" when you are transferring it via ftp from DOS to UNIX and vice versa. The ASCII mode (instead of "binary" mode, which is default) takes care of exactly this thing.

I hope this helps.
