Hello, i'am trying to perl code the following ideas i have commented as remarks but my attempts were fruitless.
Its complicated and although i tried to work some code, my code does not do what the remarks say. 
my @files = glob "$ENV{'DOCUMENT_ROOT'}/data/text/*.txt";
my @menu_files = map m{([^/]+)\.txt}, @files;

my @dbfiles = $db->do( 'SELECT title, body FROM articles' );
my $replace = $db->prepare( 'INSERT INTO article (title, body) VALUES 
+(?, ?)' );


foreach ( @menu_files ) {

   #Check every filename(item in @menu_files) as well as its content t
+o see if is already inserted in table articles under columns title an
+d body
   
   #============ INSERT NEW FILENAMES & CONTENTS INTO DATABASE IF ANY 
+=============
   #If filename and content don't already exist in the db then do inse
+rt them
   
   #=====  UPDATE THE DB ENTRY IF THERE IS A MODIFICATION IN A FILES C
+ONTENTS =====
   #If filename exists in the db under column title but its content is
+ different from the database's content then update column body in the
+ db
   
   #========  DELETE ANY DB ENTRY OF A FILENAME THATDOESNT EXIST ANY M
+ORE =========
   #Delete all db records that doesnt have a corresponding filename in
+ the hdd
}
