Falsehoods programmers believe about addresses

This is an anchor-linked version of the excellent, amazing original opus magnum by Michael Tandy.

An address will start with, or at least include, a building number.

Counterexample: Royal Opera House, Covent Garden, London, WC2E 9DD, United Kingdom.

When there is a building number, it will be all-numeric.

Counterexample: 1A Egmont Road, Middlesbrough, TS4 2HT

Introduction

Sometimes you want to be able to debug a bash script. Usually the -x option will suffice but sometimes something more sophisticated is needed.

In such instances using the DEBUG trap is often a good choice.

Attached to this gist is a example script to demonstrate how such a thing would work.
