matching question (real newbie...not like you fake newbies out there...)

[Stout, Joel R]

I want to get the file names of all "EDI" files from a certain directory.  I
do not want "ENT" (or encrypted) file names.  

Example:

The directory contains:
a001.edi
a002.edi
a003.edi.ent
a004.EDI

After getting the file name in $_ I did the following match:

if (/edi\b/i) { # thinking I would match file names 1, 2, and 4.  Instead I
matched on all.  Wasn't \b supposed to help me out here?  Or does Perl
consider "." in this case a word boundary?  Any help much appreciated.
