This article explains how to correctly handle filenames in Bourne shells (the primary shell of Unix/Linux/POSIX systems), based on the issues discussed in ‘Fixing Unix/Linux/Filenames’. Many programs fail to work properly on filenames that include spaces, begin with dash (-), include newlines, and so on, because developers don’t know how to do it properly. Many texts, even good ones, get this wrong.</p>
