Here is what the original database looks like.  
 
1245|Item A|Category 6 
1464|Item B|Category 4 
 
This would be the 2 seperate text file. 
 
filename: 1245.txt 
1245|This is the description for 1245 
 
filename: 1464.txt 
1464|This is the description for 1464 
 
This is what I would like to happen with the new database. 
 
1245|Item A|Category 6|This is the description for 1245 
1464|Item B|Category 4|This is the description for 1464

   
  
my @new_file;   
  
open <main file;   
  
while (<main file>) {   
  
    get the description file and the rest of the fields;   
  
    open <description file;   
  
    get the description;   
  
    push(@new_file, $all, $the, $relevant, $fields, $from, $both, $files);   
  
    close description file;   
  
}   
  
close main file;   
  
open >main file;   
  
write the contents of the @new_file to the main file;   
  
close main file;
