$&

$&

The string matched by the last successful pattern match (not counting any matches hidden within a BLOCK or eval() enclosed by the current BLOCK).

See Performance issues above for the serious performance implications of using this variable (even once) in your code.

This variable is read-only and dynamically-scoped.

Mnemonic: like & in some editors.
