Tech Tip: Using Figlet to Spice Up Your Scripts
Shell Scripts are very useful but not all that fun to look at. They have simple user input and output text. But, there is a way to spice up your scripts and make them a bit more eye catching with a simple program called "Figlet".
Figlet is in the repositories for most distributions of Linux and is very simple to use. If you've used the "echo" command (which you probably have) you already know how to use the basic functionality of Figlet. Here's an example of "echo" and "Figlet" next to each other:
You can see that Figlet's ASCII art style output will catch someone's attention more then the regular echo output would.
You can display the content of a file using Figlet like this:
If you would like to display the output of a command using Figlet simply pipe the command into Figlet:
Figlet comes with a few different font styles. To see a list of available fonts use the "figlist" command. To choose a font use the "-f" switch:
Here is a little script I wrote to display what each font looks like.
#!/bin/bash figlist | while read font do figlet -f $font "$font" done
If you would like to have a nice looking clock in your terminal window you can use this script
#!/bin/bash while [ 1 ]; do clear date +%r | figlet sleep 1 done
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
