Sed one-liners

A few weeks ago I reviewed Peteris Krumins’ book Awk One-Liners Explained. This post looks at his sequel, Sed One-Liners Explained.

The format of both books is the same: one-line scripts followed by detailed commentary. However, the sed book takes more effort to read because the content is more subtle. The awk book covers the most basic features of awk, but the sed book goes into the more advanced features of sed.

Sed One-Liners Explained provides clear explanations of features I found hard to understand from reading the sed documentation. If you want to learn sed in depth, this is a great book. But you may not want to learn sed in depth; the oldest and simplest parts of sed offer the greatest return on time invested. Since the book is organized by task — line numbering, selective printing, etc — rather than by language feature, the advanced and basic features are mingled.

On the other hand, there are two appendices  organized by language feature. Depending on your learning style, you may want to read the appendices first or jump into the examples and refer to the appendices only as needed.

For a sample of the book, see the table of contents, preface, and first chapter here.
