Err...Are we talking a line feed here?  Each line in a file is terminated by 
\n (a line feed).  Obviously the code you posted would work fine for lopping 
off the line feed.  You could make it work for you instead by putting each 
string on a separate line and just exploding the string returned by 
read_file on \n, skipping a step, but I suspect that approach might not be 
appropriate for what you are doing.
