I'm not sure if this is good solution, because it matches also those,
you won't:

what about this:
print "PIC is $1" if ($file_name =~ /\.(tif?f|jpe?g)$/i);

Sorry bout that blank email...
anyway... I thnk this would work
$filename =~ /(?:jpe?g$)|(?:tif?f$)/i
I think this one is wrong because you actually have
two patterns here...
if ($file_name !~ /tif$/i | /jpg$/i) {}
maybe you could try doing it like this..
if($file_name !~ /(tif$)|(jpg$)/i
no

This one worked for me:
/^.*\.[tj][pi][gfe].*$/
Hope this helps

I tried everything I could think of to get this to work before pleading for
help!
I need to check if a file is either a TIFF or JPEG graphics file.
(Case-insensitive variations of qualifying suffixes would be .tif, .tiff,
.jpg and .jpeg.) So far I have three difference versions of what seem to be
12 matches
