You are reading the file twice in each while loop. Whenever you access <PASSWD>, it returns a line and moves to the next line of the file.
So in "while (<PASSWD> ) {" it returns one line of the passwd file .
As you are reading the line again in "my @passwds = split /:/, <PASSWD>;", you are missing out on the previous line.
