While deleting files in OS X simply involves moving them to the trash and emptying it, this routine does not remove the data of these items, but instead only clears the directory entry for them. The content of the items is kept on disk with the system having no way to access it; as a result, there is potential for the content to be scanned and recovered by data recovery tools.

To prevent this from happening, you can use secure-erase features in OS X, one of which is to securely delete the files in the Finder by choosing this option … Read more

If you regularly script tasks in the Terminal, you might find at times that handling windows can be a burden. While an unused Terminal window can quickly be closed by pressing Command-W or clicking the red button at the top of the window, if you run numerous scripts then you may be left with a number of windows to close.

One way you can better manage these windows is to change the default Terminal behavior for when a terminal shell exits. By default, the Terminal will keep the window open and display the text "[process completed]," leaving you … Read more

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

Prosecutors accused Shahin Abdollahi, aka "Sean Holdt," and Jeffrey Thomas Wilkinson of hacking at least 13 point-of-sale (POS) terminals to install software that fraudulently loaded at least $40,000 onto Subway gift cards, according to an indictment unsealed in Boston on Friday (see below).

Apple's Spotlight offers a quick way to find user files and resources like applications or system preferences. However, it does not locate items in the system folder or in hidden folders, though at times you might need to access them. This limitation may be especially cumbersome to deal with if you are troubleshooting a problem in OS X or helping someone do so, meaning you may need to ask them to locate a specific hidden file and remove it or modify its contents.

For some system resources you can simply navigate through the Finder; however, in its default view … Read more

The OS X Terminal is a very powerful tool for configuring and using a Mac, and can be used to script and program a number of aspects of the computer's operations; however, its text-based interface can be a bit of a cryptic environment to first-timers, especially when it comes to finding out what you can use it for.

There are thousands of Terminal commands available, but when you first launch it you might not have a clue where to look for them. Of course there are basic commands like "ls" for listing directory contents or "cd&… Read more

If you need to adjust network settings on your Mac, the quickest route is to do so through the OS X system preferences and menu extras. However, you can also make these changes -- adding and removing ports, creating new locations, switching to DHCP from manual configurations, changing MTU sizes, and managing 802.1x profiles, among others -- via the command line.

The utility for doing this is the command "networksetup," which can be used to quickly apply a change to a specific network property. This tool covers every aspect of the Mac's network setup and you … Read more
