Why are you using a hash to store what seems like a simple list of file names? I would use a simple @array.

use the perl grep function to search an array.

Don't you see the contradiction in these two sentences? I'd use a hash, but with the names read into the keys, not the values. That way, you can easily check whether a filename is in the hash. For example, 

while(<>) { /(.*)/; $names{$1} = 1; } 
use File::Find (); 
File::Find::find sub { 
    $names{$_} and -x and print $File::Find::name, "\n"; 
    }, grep -e, split ":", $ENV{"PATH"};

searches for binaries with the names given on ARGV.
