Take the following quote as an example. I parsed it through a readability checker. http://www.online-utility.org/english/readability_test_and_improve.jsp That gave a Gunning Fog Index of 14, and a Flesch Reading Ease of 38. The following URL explains that this excerpt looks like a highbrow newspaper. Authors should try to make it more easily understood.
Variable expansion is the only type of expansion performed on double quoted strings. There is, however, an important difference in how variables are expanded when quoted and when unquoted. An unquoted variable expansion will result in a variable number of arguments. For example, if the variable $foo has zero elements or is undefined, the argument $foo will expand to zero elements. If the variable $foo is an array of five elements, the argument $foo will expand to five elements. When quoted, like "$foo", a variable expansion will always result in exactly one argument. Undefined variables will expand to the empty string, and array variables will be concatenated using the space character. http://ridiculousfish.com/shell/user_doc/html/index.html#expand -- www.netspeed.com.au/bryan/ ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
