Monks,

I have this little script that I'm using to disable unneeded services in Linux. It works fine the first time around, but when I run it again, say because I added a new service, it moves all of the other files like so:
 .NO..NO.K74apmd

I thought my regex would not match on a .NO, so I'm not sure what's wrong. What should I do to make sure it won't match anything with a .NO in front of it? I haven't been coding much lately so please be kind if it's really obvious :-) 
#!/usr/bin/perl -w

use strict;
 
# Script used to disable services that are not needed
 
my @dirs = qw(rc0 rc1 rc2 rc3 rc4 rc5 rc6);

my $expression = "autofs|apmd|isdn|lpd|netfs|nfs|nfslock|nscd|portmap
|radvd|rstatd|rusersd|rwalld|rwhod|sendmail|ypbind|yppasswd|ypserv
|ypxfrd";

my $result;

my $i;
 
for $i (@dirs){
 
  opendir (DIR, "/etc/$i.d") or die "Can't open directory $_\n";

  while (my $name = readdir(DIR)){

    my $cmd1 = "/bin/mv /etc/$i.d/$name /etc/$i.d/.NO.$name" or print 
    "/etc/$i.d/$name not found\n";

   `$cmd1` if $name =~ /\b(K|S)\d{2}?$expression\b/;
  }
  closedir DIR;
}
