uid script help
i need a script to process a password file and based on the UIDs in the password file, generate the new UID that is 1 greater than the highest uid.
i have some script logic but i dont really understand it. any help?
Code:
    #!/usr/bin/perl
   
  ##########################################
    # ITEC 400
  # Script name: newuid.pl
  # Case Number 1: ./newuid.pl small_passwd
  # The small_passwd file is located ~/public_html/itec400/Misc
  # The name of the file must be specified on the command line.
  # Functionality: The newuid.pl script reads the uids in the small_passwd
  # file. The script determines the highest numbers uid currently
  # in use, and adds one to it for the next user.
  ##############################################
   
  for $XXXX(@ARGV) {
  $counter++;
  }
   
  if ($XXXXXXX != 1) {
  print "Error. Need one argument.\n";
  }
   
  if ($XXXXXXX == 1) {
   
  $flag = 0;
   
  exec `XXX -f3 -d":" /export/home/dandrear/public_html/itec400/Misc/$XXXX[]> "uidoutput"`;
   
  open (reader, "uidoutput");
   
  while ($line = <XXXXXX>) {
   
  $firsttest = $XXXX;
   
  if ($XXXX == 0) {
  $secondtest = $XXXXXXXXX;
  } # end if
   
  $flag = 1;
   
  if ($secondtest < $XXXXXXXXX) {
   
  $secondtest = $XXXXXXXXX;
   
  } #end if
   
   
  } # end while
   
  $newIDNum = $XXXXXXXXXX + 1;
   
  print "The new User ID number is ";
  print $XXXXXXXX;
  print "\n";
   
  } # end if
