What makes it worse is some of the idiotic comments posted under the article. Some of those comments really make us wonder about the future of humanity. Fortunately, there are many other comments that indicate that people do understand that this is a real problem. We just wish there were more of them!

Article series: CommandLineFu, BASH, AWK, Perl, SED One-Liners Explained

We must confess that we are not as fond of the Linux command line as some Linux users — we’ll take a good GUI, and a mouse over a keyboard any time we can. But for those that love working at the Linux command prompt (and that probably don’t make nearly as many typos as we do), we thought you might appreciate this series from the catonmat blog:
