Re: need some help

The syntax error is because you need to escape the backslash like so

$b = split(/$domain\//,$a);

But as was suggested, the URI module may be more useful

Update I was just pointing out the syntax error, since the solution had already been covered.

I have to say that $a and $b should not be used! They are package global variables used by sort. Now that I have said that: I see a problem... split returns a list not a scalar. Use one of the following types of statements instead: `@list = split(/$pattern/, $expr);` `$scalar = (split(/$pattern/, $expr))[0];` `($scalar) = split(/$pattern/, $expr);`	[reply] [d/l] [select]

From the docs: split Splits a string into a list of strings and returns that list. By default, empty leading fields are preserved, and empty trailing ones are deleted. In scalar context, returns the number of fields found and splits into the @_ array. Use of split in scalar context is deprecated, however, because it clobbers your subroutine arguments.
