Larry Wall, creator of the Perl programming language, discusses why he developed Perl, the backstory on Perl's multiple backronyms, and the future of Perl.

Squeezing out the white space

Ever need to clean up some sloppy text? You can squeeze out extra white space with some very simple Perl commands. Let's take a look at how this works.

Port Forwarding with Perl

SSH tunnels aren't the only way to do port forwarding. If you're clever enough, you can write your own program. If you're not quite that clever, you can use someone else's program -- like a very cool Perl script I found on the web.

The state of the scripting universe

With the rise of Web 2.0, scripting languages (also called dynamic languages) are now often considered important tools in a developer's arsenal. That's a far cry from than their old reputation as lesser tools for those who can't handle "real" programming. Almost 70 percent of the 1,200 developers surveyed by Evans Data for its most recent Global Development Survey currently use JavaScript. PHP is used by just over a third of developers, and Perl has captured about a quarter of developers

Connection testing with Perl

If you've never used the Perl Sockets module for basic connection testing, you might be surprised at how easily you can craft a very useful script. I find my version of a Perl "listen" script to be as useful as a cable tester!

Redirecting standard error in Perl

jnaze — Tue, 14 Aug 2007 12:15:04 -0400

There are numerous ways to redirect standard error in a Perl script. You can redirect the output from one particular command, you can combine standard error with standard out so that the two are handled together or you can send all standard error to the bit bucket. None of these techniques depends on what the person running the script does. Instead, they can all be set up in your Perl scripts. Let's take a look at how this works.

The function you use depends upon what you want to delete from the array. Delete() removes a particular index while the splice function actually removes a slot.
