8 Regular Expressions You Should Know Regular expressions are a language of their own. When you learn a new programming language, they're this little sub-language that makes no sense at first glance. Many times you have to read another tutorial, article, or book just to understand the "simple" pattern described. Today, we'll review eight regular expressions that you should know for your next coding project. Before we start, you might want to check out some of the regex apps on Envato Market, such as: You can extract emails, proxies, IPs, phone numbers, addresses, HTML tags, URLs, links, dates, etc. Extract, scrape, parse, harvest. Extract emails from an old CSV address book.Extract image sources from HTML files.Extract proxies from online websites.Extract URL results from Google.Fast regex testerAJAX-basedjQuery etc are not required.No database requiredAdvertisement ready This item is a PHP RegEx builder, which helps you to build Regular Expressions in an extensible PHP syntax. All that in a PHP syntax. my-us3r_n4m3 myp4ssw0rd

Shell Programming! A working knowledge of shell scripting is essential to anyone wishing to become reasonably proficient at system administration, even if they do not anticipate ever having to actually write a script. Consider that as a Linux machine boots up, it executes the shell scripts in /etc/rc.d to restore the system configuration and set up services. A detailed understanding of these startup scripts is important for analyzing the behavior of a system, and possibly modifying it. The craft of scripting is not hard to master, since scripts can be built in bite-sized sections and there is only a fairly small set of shell-specific operators and options to learn. In the early days of personal computing, the BASIC language enabled anyone reasonably computer proficient to write programs on an early generation of microcomputers. A shell script is a quick-and-dirty method of prototyping a complex application. What follows is a tutorial on shell scripting.

You fall off and scrape your knees a lot at first. With a bit more experience, you become comfortable riding them around town, but also quickly discover why most people drive cars for longer trips. Shell scripting is generally considered to be a glue language, ideal for creating small pieces of code that connect other tools together. If you have ever successfully trued a bicycle wheel (or paid someone else to do so), that’s similar to learning the basics of shell scripting. This chapter and the next two chapters introduce the basic concepts of shell scripting. Shell Script Dialects There are many different dialects of shell scripts, each with their own quirks, and some with their own syntax entirely. To that end, the first lesson you must learn before writing a shell script is that there are two fundamentally different sets of shell script syntax: the Bourne shell syntax and the C shell syntax. Bourne-compatible shells And so on. For example:
