Hello all,

I'm trying to simplify my subroutine that is supposed to open an (LDIF)text file, read in its contents into an array then print to a new file while excluding the lines that exist in another array.

I can currently accomplish this with just the word I want to exclude, but of course this leads to bloated code because I have to continuously open and close the file on each removal.

Here is what I have so far: 

sub GROOMLDIF {
     # Delete LDAP-internal fields
      my @erasethese = qw(structuralObjectClass entryUUID creatorsName
+ modifiersName createTimestamp modifyTimestamp entryCSN);
   
      open(FILE,"< data/all.ldif");
       my @LINES = <FILE>;
      close(FILE);
      open(FILE,"> data/groomed.ldif");
       foreach my $LINE (@LINES) {
        my @array = split(/\:/,$LINE);
        print FILE $LINE unless ($array[0] eq "$erasethese[0]");
       }
      close(FILE);

      open(FILE,"< data/groomed.ldif");
          @LINES = <FILE>;
      close(FILE);
      open(FILE,"> data/groomed.ldif");
       foreach my $LINE (@LINES) {
        my @array = split(/\:/,$LINE);
        print FILE $LINE unless ($array[0] eq "$erasethese[1]");
       }
      close(FILE);
}

I would like to combine all of them into one open/close. I've tried a nested for-loop that incremented with no luck.

Any help would be appreciated.
