Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

hmm, it just occurred to me that i could have a variable that =on or =off, duh, and check that for my speech actions. It would still be interesting to see what it would look like though, in a script, to execute a command unless it is between a time range, just for the sake of learning something.
I need other sounds, just not the speech synthesis. For example, when on a conference call, I often 'broadcast' portions of pre-recorded conversations, but I would not want 600-1000 people to hear my incoming email notifications or my quarterly time announcements.
I have figured out how to disable the speech - I created aliases that either creates an empty file 'speech' or deletes the same file, then in my email filters, time script, etc. I just added a 'if [ -e ~/speech ] then dothis else exit'.
Now I'm just curious how to, if I ever need to, script conditional processing based on time - if it is between 8 PM and 10 PM, for example, then it's ok to process, or how to execute commands only if the time is outside those ranges.
If you're just curious, I use festival with better voices, and I use Cepstral's Swift (cepstral.com) as well, but that's not really needed for the question to be answered.
