Regular Expressions resources on the Web

In the forties, Warren McCulloch and Walter Pitts created neuron-level models of how the nervous system operates. The mathematician, Stephen Kleene [qv], later described these models using his mathematical notation called regular sets [qv or here]. Ken Thompson incorporated that system of notation into qed (the grandfather of the UNIX ed) and eventually into grep. Ever since that time, regular expressions have constantly seeped into UNIX and UNIX-like utilities. [primary source]
