Part of the series: Learning sed

Episodes about using sed, the Stream Editor. It's a non-interactive editor which you can use to make simple changes to data, which is how many people use it. However, sed also has a lot of hidden power, especially in the GNU version.

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.
