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 anotherAnd 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.
