here is how my config file looks like:
==========================
#Config info
#
#
DATABASE,NODE,file1,user1,passwd1
DATABASE,NODE,file2,user2,passwd2
#
#
===========================
HERE IS WHAT I WANT TO DO:

(1). OPEN THE CONFIG (ITS IN THE DIRECTORY: A/B/CONFIG/configfile)
(2). parse the each line that begis with DATABASE
(3). get all the file(S), user(s) and passwd(s)

(4). Then I need to connect to the files cause they are databases..
       i know how to do that already all i need is the parsing of the file to get
      the desired info.

THANKS ALOT.

try this.
i does what you want.

=================coder.pl
#!/usr/local/bin/perl

open(CONF,"/A/B/CONFIG/configfile") || die $!;
@lines<CONF>;  ## Read all the lines in the file
close(CONF);

foreach $line (@lines){
  next if $line=~ /^#/; ##  Ignore comment lines
  chomp($line); ##  Remove the \n
  ($db,$node,$file,$user,$pass)=split(/,/,$line);
  if ($db=~ /^DATABASE$/){
    print $user," & ",$pass,"\n";
    ## Add your connect code here!!
  }
}

try using
 
@lines = <CONF>;


instead of

@lines<CONF>



and use

if ($db=~ /^DATABASE/){

instead of
   

if ($db=~ /^DATABASE$/){

the error is cause of the line..
@lines<CONF>;  ## Read all the lines in the file

it should be...
@lines=<CONF>;  ## Read all the lines in the file

Sorry :-0
