To strip off a prefix in a variable..

[clearguy02]

Hi all,

I have the following variable:

$a = "xxx_active_jsmith";

Now I want to strip ohf the prefix, xxx_active_ and want to store only
the id, jsmith into the variable $b. That means, it should be $b =
"jsmith";

How can I do that?

Thanks
J

( $b ) = $a =~ /([^_]+)\z/;


( $b = $a ) =~ s/.*_//;
