Let’s try that again:<\/p>\n $ echo “scale=2;155\/12” | bc Yeah, that many years. Almost 13 years of writing about shell scripts and lightweight programming within the Linux environment.

Before starting, however, pull out a piece of paper and jot down how you’d solve it.<\/p>\n Normalizing Filenames for the Web<\/p>\n My strategy is going to be easy: pull the string apart into individual characters, analyze each character to identify if it’s an alphanumeric, and if it’s not, convert it into its hexadecimal ASCII equivalent, prefacing it with a “%” as needed.<\/p>\n Read more at Linux Journal<\/a><\/p>\n
