While the need to locate a specific line in a text file may not be a very useful feature in regular prose text, for managing structured code such as scripts and XML files that are common in OS X, being able to identify a specific line or two may be quite useful.

If you have attempted shell scripting in OS X, you may find that when your scripts run into errors you will be given a brief description of the problem that includes the line where the problem occurred. While the use of BBEdit, TextWrangler, and other powerful text editors … Read more

You have plenty of choices when it comes to tools for editing the EXIF metadata contained in your digital images and other files, everything from dead-simple freeware to pro-level applications running into three figures. ExifTool definitely belongs among the freeware, but whether it's a simple tool depends on how you feel about the Windows command line. If you have no idea what that is, ExifTool is not for you; much friendlier metadata tools aren't scarce. But if you can handle Perl or have no problem with the Command Prompt (or typing characters and spaces) then ExifTool offers a … Read more

Imagine yourself as England's Frank Lambard playing against Germany in a preliminary match during the 2010 FIFA World Cup. After kicking a solid game-tying shot, you watch the ball oddly bounce downward off the top rail, then in and out of the goal. Even though video footage proves otherwise, the referees disallow the score and Germany eventually goes on to win the game.

Fortunately, such epic miscalls seem less likely to happen during the 2014 World Cup and beyond, as the soccer-regulating organization FIFA plans to utilize a highly accurate sensor system capable of detecting successful shots and ensuring the referees should get the call right every time.… Read more

At a street price of around $50 for a kit of two units, the Actiontec 500 Mbps Powerline Network Adapter Kit is a bargain. And that's not the only good thing about it.

The kit, retail model number PWR511K01, comes with two identical adapters, currently the smallest of their type, that offered very good performance in my testing.

The only real complaint I have is that these adapters don't support Gigabit Ethernet, hence offering the limited data rate of the regular Ethernet standard at most. However, the affordable price and the supercompact design still make the kit an … Read more

As with many other Unix-like systems that have a BSD interface, OS X includes a fully Unix-compliant terminal that can be accessed with a Unix shell in the included Terminal utility. This feature allows for a relatively powerful way to access and modify system settings to customize and troubleshoot the system.

As with the rest of the system, this command-line interface is by default limited by standard permissions restrictions so only administrators may access system files and only users may access their own files. To get around this, the sudo command is commonly invoked to execute commands as another user, … Read more
