Several of the books in the lower tiers are ones I&amp;#x27;d recommend skipping and go to online resources, instead. It may not still be so, but when I last looked at the O&amp;#x27;Reilly bash books, many years ago, the TLDP bash programming HOWTOs were more pragmatic and easy to follow (I think that&amp;#x27;s here: &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;tldp.org&amp;#x2F;HOWTO&amp;#x2F;Bash-Prog-Intro-HOWTO.html&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;tldp.org&amp;#x2F;HOWTO&amp;#x2F;Bash-Prog-Intro-HOWTO.html&lt;/a&gt; and &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;www.tldp.org&amp;#x2F;LDP&amp;#x2F;abs&amp;#x2F;html&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;www.tldp.org&amp;#x2F;LDP&amp;#x2F;abs&amp;#x2F;html&amp;#x2F;&lt;/a&gt; ). I guess UNIX in a Nutshell was good in its day, but is quite old now, even in its 4th edition.&lt;p&gt;&lt;i&gt;DNS &amp;amp; BIND&lt;/i&gt; is one I recommend to anyone who ever has to touch anything related to networks, because so many problems I have seen in my 20 years of troubleshooting network problems have come down to someone not understanding DNS. It&amp;#x27;s well-written, covers the how and why, and covers everything from &amp;quot;I have one website&amp;quot; to &amp;quot;I run a dozen data centers with thousands of zones and thousands of queries per second&amp;quot; (and the authors have significant experience at all of those levels).&lt;p&gt;And &lt;i&gt;Essential System Administration&lt;/i&gt; is a classic, though a bit dated the last time I looked at it (I mean, the core services and concepts it covers are relatively timeless, but it&amp;#x27;s missing a lot of modern cloud and service-based concepts).&lt;p&gt;That said, nearly all of these were first written (their first editions) when O&amp;#x27;Reilly was publishing incredibly high quality books; well above anyone else in the industry, particularly for OSS and Free Software topics. So, probably a good value, if you haven&amp;#x27;t already read them and don&amp;#x27;t have a good foundation of knowledge of these topics.</text><parent_chain></parent_chain></comment><story><title>Humble Book Bundle: Unix</title><url>https://www.humblebundle.com/books/unix-book-bundle</url></story>

I&amp;#x27;d rather have less books but then in a printed format. I have noticed that I can&amp;#x27;t concentrate on reading books when they are presented to me on my computer screen. I do have a kindle (1st or 2nd generation) and that device doesn&amp;#x27;t support PDF well, furthermore it is rather slow. It works fine for regular books though, where I don&amp;#x27;t have to flip through chapters back and forth often.</text><parent_chain></parent_chain></comment><story><title>Humble Book Bundle: Unix</title><url>https://www.humblebundle.com/books/unix-book-bundle</url></story>
