I just wrote my second e-book. This time it's about sed one-liners. Sed one-liners teaches you sed, the superman of Unix stream editing, through various practical examples, such as numbering lines, printing certain lines, converting text, etc. The book is 98 pages long and contains precisely 100 well explained one-liners. Have a look!

sed can select lines in a file that can be individually modified, printed or deleted. sed is able to select and number any of lines within a file.

"A new version of GNU sed has been released [...] This is the first stable release of GNU sed to adopt version 3 of the GNU General Public License. It is also the first release to use gnulib to achieve maximum portability..."

"This is the second part of a three-part article on the famous sed one-liners. This part will explain sed one-liners for selective printing of certain lines. See part one for introduction of the series..."

"sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline). While in some ways similar to an editor which permits scripted edits (such as ed), sed works by making only one pass over the input(s), and is consequently more efficient.

An updated version of the updated version of the Thesaurus script we put up a while ago. Many thanks :)
