oops... I forgot you just wanted the filename. Try this instead of all previous suggestions:

Code:
my @array;
open (FH, 'yourfile') or die "$!";
while(<FH>){
   chomp;
   tr/://d;
   if (m#/(\S+)\s*\d*$#) {
      push @array, $1;
   }
}
close FH;
print "$_\n" for @array;

tr/://d; <-- removes all colons from the lines
(split(/s\s+/))[-2] <-- splits the line on spaces and returns the second to last field. It is called an array slice.
