Alternatively, you can check the return code of the execution. (see perlvar) 
my $cmd = "rsh $file"; # or whatever
my $output = qx/$cmd/; # qx// is the same as ``
my $rc = $?;                # $? is a special Perl variable 
if ( $rc ) { 
  print STDERR "No Match\n"; # you just want to print and continue, ri
+ght?
}
