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 pi 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 your coding skills as you learn to conquer those pesky tasks in a few precisely placed keystrokes with Perl One-Liners.
