Unix notable and Perl disciple Randall Schwartz had begun handing out these embarrassing awards around 1995 to people who used commands such as <code>cat myfile | head -3</code> when they could more easily have used <code>head -3 myfile</code>. Wasting system cycles and spawning unneeded processes is not a big sin when it comes to Unix, but it's clearly both wasteful and, well, indicative of users who are either falling into a bad habit or just not paying attention.</p> Data Center Open Source Software Linux Mac OS X Unix Tue, 26 Mar 2013 10:45:17 +0000 Lab Notes 215189 at http://www.infoworld.com Unix: Rooting out the rootkits http://www.infoworld.com/t/unix/unix-rooting-out-the-rootkits-214944?source=rss_unix <p>Rootkits are both tricky and stealthy, but there are still some things that you can do if you suspect that one of your Linux system has been infected.

Rootkits are still one of the most stealthy, potentially damaging and ultimately viable problems that can plague your systems. And they don't just infect Unix systems. Windows systems are also vulnerable to rootkits with the same concerns for detection that have made them such a problem on Unix systems. In fact, smart phones are just as vulnerable to rootkit attacks as the operating systems in your data center.</p> Data Center Open Source Software Linux Mac OS X Unix Sun, 03 Mar 2013 10:00:00 +0000 Lab Notes 214613 at http://www.infoworld.com Unix: Under the spell of magic numbers http://www.infoworld.com/t/unix/unix-under-the-spell-of-magic-numbers-214585?source=rss_unix <p>Magic numbers play a very important role on Unix systems.

Magic numbers are values, not generally visible unless you dump file contents using a command like od that displays file contents in hex, that serve as signatures for file type identification. Some are fairly obvious once you see them -- like if you spot "\x89PNG" in a file dump.
