Paul,
That line worked great! Thank you very much!.
Meanwhile I managed to cook up something with a lot of bells and whistles
(of course just after I posted a cry for help!)
It is not nearly as elegant as your line but it does some other things as well:

--------------------snip------------------------------------
#!/usr/bin/perl
# This script locates a file and then puts that file in an imageviewer
# if it is a jpeg file.
# Usage: peek <filename.jpg>

$x = $ARGV[0];

if ($x eq help || $x eq "" ) { print "Usage: peek <filename>\n"; exit; }

system ("locate $x > peeklist");

open(FILE, peeklist) or die "Can't open $!\n";
while (<FILE>) {
        $output .= $_;
        if ( $_ =~ /.jpg\b/ ) {
                print "Now showing: $_\n";
                system ("display $_");   # Works with gqview, ee, kview, display
(ImageMagick), gimp.
        } else {
                print "Not a jpeg file:  $_\n";
        }

        print "Continue?  ";
        $yesno = <STDIN>;
        chomp $yesno;
        if ($yesno eq "no" ) {
            close (FILE);
            print "Total: \n$output\n";
            system ("cat peeklist >> donelist");
            exit;
        }
}
close (FILE);
print "Total: \n$output\n";
system ("cat peeklist >> donelist");
