Riassunto:

Part of the fun of programming in Perl lies in tackling tedious tasks with short, efficient, and reusable code. Often, the perfect tool is the one-liner, a small but powerful program that fits in one line of code and does one thing really well.

In Perl One-Liners, author and impatient hacker Peteris Krumins takes you through more than 100 compelling one-liners that do all sorts of handy things, such as manipulate line spacing, tally column values in a table, and get a list of users on a system. This cookbook of useful, customizable, and fun scripts will even help hone your Perl coding skills, as Krumins dissects the code to give you a deeper understanding of the language.

You'll find one-liners that:

• Encode, decode, and convert strings
• Generate random passwords
• Calculate sums, factorials, and the mathematical constants p and e
• Add or remove spaces
• Number lines in a file
• Print lines that match a specific pattern
• Check to see if a number is prime with a regular expression
• Convert IP address to decimal form
• Replace one string with another

And many more! Save time and sharpen you coding skills as you learn to conquer those pesky tasks in a few precisely placed keystrokes with Perl One-Liners.
