Introduction to sed - part 2
In the last episode we looked at
sed at the simplest level. We looked at three command-line options and the 's' command. We introduced the idea of basic regular expressions.
In this episode we will cover all of these topics in more detail.
We are looking at GNU
sed in this series. This version contains many extensions to POSIX
sed. These extensions provide many more features, but
sed scripts written this way are not portable.

Note: Since recording the audio I have added a sixth example to the full notes to cover the topic of word boundaries, which I had omitted at the time.
