Parsing an RSS News Feed with a Bash Script

By Jim Hall

I can automate an hourly job to retrieve a copy of an RSS feed, parse it, and save the news items to a local file that the website can incorporate. That reduces complexity on the website, with only a little extra work by parsing the RSS news feed with a Bash script.

 

Hacking a Safe with Bash

By Adam Kosmin

Being a minimalist, I have little interest in dealing with GUI applications that slow down my work flow or application-specific solutions (such as browser password vaults) that are applicable only toward a subset of my sensitive data. Working with text files affords greater flexibility over how my data is structured and provides the ability to leverage standard tools I can expect to find most anywhere.

 

Graph Any Data with Cacti!

By Shawn Powers

Cacti is not a new program. It's been around for a long time, and in its own way, it's a complicated beast itself. I finally really took the time to figure it out, however, and I realized that it's not too difficult to use. The cool part is that Cacti makes RRDtool manipulation incredibly convenient. It did take me the better part of a day to understand Cacti fully, so hopefully this article will save you some time.

 

Reading Web Comics via Bash Script

By Jim Hall

I follow several Web comics. I used to open my Web browser and check out each comic's Web site. That method was fine when I read only a few Web comics, but it became a pain to stay current when I followed more than about ten comics. These days, I read around 20 Web comics. It takes a lot of time to open each Web site separately just to read a Web comic. I could bookmark the Web comics, but I figured there had to be a better way—a simpler way for me to read all of my Web comics at once.
