Query: Great book for picking up Perl

It is a very useful book that covers many useful aspects. It does so quickly, without that filler that many books like to have to make themselves thicker. If you've never done programming or scripting, you might get lost in the first chapter (for example, there are nested conditional loops on page 14). Luckily, the later chapters go on to explain all of this.You get some real juice, too: file/directory manipulation, handling processes, registry editing, database connectivity. It definitely gets your feet wet with what you can do with Perl.
