You certainly shouldn't run a linux script containing commands like...
wget http://www.planetarypinball.com/reference/partsmanuals/WMS_Parts_1966/files/assets/pages/page0001.swf?rnd=e036838d82b9db95cda2d380c70d5d44 -O Page0001.swf
which incrementally downloads each page from their website to get all the SWF files the pages are formatted in...
and then fall short of success by forgetting to ask the wife to convert all of the SWF files into one pdf using something like Adobe Acrobat Pro.
