In defense of the trusty old CLI

Here’s a tongue-in-cheek presentation I did in defense of the trusty old CLI 🙂

Using the Command line is good for you!

Although it’s pushing 40, the unix command line is still very much in use today, in the form of the modern (GNU) bash shell and a few proprietary implementations like ksh. An interesting story follows.. it matches my experiences with log analysis on a linux environment. Perl, Ruby etc have their advantages,but Unix tools are still a low friction way to solve bulk text processing problems.

Perl, sed, grep, gawk, uniq, host and dig: another look ||
None of the above programs are sexy or buzzword compliant. Because of modern scripting languages they are largely ignored or at best under utilized. A number of years ago, I was mentored by a Unix guru who knew his way around the Unix command line to the point that years later I marvel at his ability to be productive on a command line while working with Unix.

I work at a large ISP with a mix of every operating system possible so most won’t find this useful. However, the following gave me an opportunity to revisit standard Unix/Linux command line tools and how to put them to good use. By doing so I remembered how important these tools are and how robust Unix/Linux is. In this regard, you might find this very useful as well. When nothing else will do the standard Unix tools are hard to beat.
