FC20 and (":No such file or directory)

[Gregory P. Ennis]

Everyone,

I have created a new F20 install on a Toshiba laptop this afternoon, and
everything has gone well until I tried to set the laptop up for our
system with some perl scripts.  
Some of the perl scripts worked fine, but one script would not activate
and resulted in a command line error message of :

(": No such file or directory)

I added the parenthesis, but the initial single quote is part of the
message.  I have evaluated the perl script and have run it on other
machines without difficulty.  

I finally got the script to work by adding a -w switch to the first line
in the form of :

#!/usr/bin/perl -w
 
I am posting this to record the problem and solution for others.
