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.
