I need to do a couple of things.  First I need to get all the * 's out of a variable and also any -- , i just need to git rid of them, not replace them.  And also the more difficult of the two i believe, i have a varibable, say, $post, i need to check to see if it has www. something, i need to change that into <a href=www.whatever>www.whatever</a> cause on a chat i need to allow them to show links, html code is normally stripped. So the $post shold remain the same except change www. into <a href.. etc.  Thanks for the help in advance.  Any questions just post.

$variable =~ tr/-*//d;

$variable =~ tr/-*//d;

$post =~ s|(\bwww\.\S+)|<a href=$1>$1</a>|gi;

#You didn't say how to tell the end of "whatever"
#the above code assumes it ends with a blank character
