I love writing about programming and it's something I am passionate and excited about. So far I have written three books. I am writing the fourth book right now and I don't see myself stopping!
Awk One-Liners Explained
Awk One-Liners Explained teaches the basics of the Awk programming language through 70 short and well-explained Awk programs. These short programs are called one-liners. They fit on a single line and they perform one task really well. The tasks include numbering lines, joining lines, separating lines, printing columns, doing calculations, printing certain lines, deleting certain lines, replacing certain words and others.
Sed One-Liners Explained
Sed One-Liners Explained teaches the
sed Unix utility through 100 short and well-explained examples. These short programs are called one-liners. They fit on a single line and they do one task really well. The examples include numbering lines, printing certain lines, deleting certain lines, changing, deleting and replacing words and many others.
Also I made the first chapter of the book freely available and called it World's Best Introduction to Sed. Take a look!
Perl One-Liners Explained
Perl One-Liners Explained teaches you how to become the shell ninja through 130 short and well-explained Perl programs called one-liners. Since there is more than one way to do it in Perl, I usually present several alternatives so the total number of various one-liners is over 200.
