Well, I have a new series on SED starting Monday August 19th. I hope to show the ins and outs of SED. I'm guessing there will be some where between 15 and 20 videos in the series by the time I'm done. Mainly because I need to learn SED better and I learn best by teaching my viewers. 🙂
Yes, you can pass SED both Variables from your shell environment and also use Regular Expressions. But, because of your comment, I have decided to do a series on SED. So, keep an eye out. In 2 or 3 weeks I will start posting SED Videos ever Monday for a while.
