I’m glad to present you my new article. This article describes UNIX utilities I use to collect information about handheld computers. You will find here tips how to clone websites, download webpages, YouTube videos, Google books, files from SourceForge, etc. Other collectors may find this overview interesting and useful, so I decided to share. Please note that I run all the mentioned utilities in GNU/Linux. I’ve no information whether they support other operating systems (Windows, macOS).
