in thread asterisk use

In the subroutine named "wanted" that find2perl creates there is usage of the "&&" operator. If I understand it correctly, it's evaluating each expression, and if they evaluate to "true" it prints $name. Is the last "&&" necessary? There are no expressions after it; just goes to the print statement.

sub wanted { my ($dev,$ino,$mode,$nlink,$uid,$gid); (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) && -d _ && print("$name\n"); }

    $foo && $bar && print "something"; is equivalent to print "something" if $foo && $bar;. The last && is necessary in your code because only that makes the whole thing one expression.
