More Mad Computer Science? (Simple multi-threading in a shell script)

Posted 01-20-2012 at 10:02 AM by rainbowsally

Just dropping by? Here's an easy one. And it's kind of fun.

We've already created a launch utility in this blog, but let's create one that works on other folks systems so they don't need to "install" (so to speak) anything to get the benefits of the functionality.

First let's look at the principles involved

Let's read fstab as a normal user. Don't 'su' or 'sudo su' here, because we don't actually want to be able to write to it. Just picking...

With tax season coming up I have been asked to set up a certain centralized tax service for a company.
