Use "read" with a text file with comments

Hi, I read a .txt file with read command.
Code:
while read PC USER PASS SHARE EXCL
do
...
done

The file is like this:
Code:
pc1 usr pc01 parts 
pc2 usr pc02 parts nobackup
pc3 usr pc03 parts 
pc4 usr pc04 parts
pc10 usr pc10 parts nobackup
pc13 usr pc13 share,share_2 noshare,noshare_2

But if I want add a comment line (#comment) in the file the line is parsed like a normal line. On the web I founded a solution to don't parse a # line but I have lost the link.. Smilie
I use /bin/sh.

Thanks in advance, sorry for my english.

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
