I assume you are searching for filenames and not the content of the files?
Have you tried File::Find?
our @filelist = ();
our $fdir = "/usr/blah"
find(\&wanted, $fdir);
die " cannot get file list: $!" unless(@filelist>0);
#assuming the directory exists, @filelist now has all files in blah in
+cluding subdirs.
sub wanted {
my $thisfile = $File::Find::name;
push(@filelist, $thisfile)
}
See the doc for how to search using more complex criteria
