reg expressions

[Steve Buehler <steve@xxxxxxxxx>]

Ok.  I am really bad at regular expressions.  I have to search through some 
files and put the contents into an array.  A file could look like this:
$aliases=`cat /home/virtual/site$site_id/fst/etc/mail/local-host-names`;
----start of file----
# local-host-names - include all aliases for your machine here.
# Please do not add any domain names in this file.
domain.net
domain.com
----end of file----

In $aliases, I need to ignore the lines that start with a # sign.  It is 
possible, but not probably that it will be more than just the first 2 lines 
and possible that it isn't even the first two lines.  After done, $aliases 
should have just the two domain names in it.  One per line.  Then I need to 
loop through the lines in $aliases and do stuff with each line.  Any help 
would be GREATLY appreciated.  It would also be fine to just do a loop that 
checks each line.  Since I guess that would be quicker.  If the line starts 
with a #, then ignore it, otherwise, do some other stuff.

Thanks
Steve
