NOTE: This article assumes you have been following the other articles in this series. Another Note: I can’t take credit for this. I got it from a now defunct website called dotfiles.com. I don’t remember who the original author was and I’ve edited it to suit me. I won’t be explaining every little detail because some are more advanced. If you’ve been keeping up with this series, you’ll know I’ve promised you a little magic. This is it and you might learn a little something too. It’s really simple but …

Learning the Command Line – Shell Scripts

Terminal commands are great but what if you want to have something done every time you login? What if you need to do something on several files or some other repetitive action and don’t want to type in the commands every time. That could get time consuming and dreary. In this article, we will set up our Terminal environment to make certain things a little easier and get a start on shell scripting. A shell script is a text file with all the commands you want run, one after another. …

These Permissions Are Not The Repairs You’re Looking For – A Critical Look at Permissions in OS X

Screenshot 2013-11-29 11.14.32

So, your Mac is acting up. Indeed, a Mac is no more impervious to Murphy’s Law than a non-Mac PC (I use PC here in the literal sense to signify personal computer). What do you do when the inevitable occurs? The first response for many to this will differ – some will seek out a solution, some will be adept enough to tackle the problem head on, some will likely do some sort of voodoo dance (if life has taught me anything, it’s that if you can imagine it, someone …

Confessions of a Recovering Gear-aholic

Hi everybody, I’m Mike and I like to buy stuff . . . lots of stuff.   I have all the latest and greatest cameras, computers, iPads, iPods, iPhones, routers, receivers, amps, speakers, TVs, and every other conceivable gadget and gizmo. If it’s new and techie, I either already have it, or am planning on buying it. DISCLAIMER: The above statement is not totally true. I don’t really have all of that stuff, but only because of limited funds, and a wife that isn’t nearly as enamored with gadgets as I …

Learning the Command Line – File Permissions

Ever have a file you can’t do anything with? Can’t change it, can’t delete it, can’t even look at it? We’re going to find out why. FreeBSD, and by extension, OS X (which is loosely based on FreeBSD), uses file permissions. This lets the system control access to files and directories by different users. Would you want another user looking at your files? Of course not. Permissions determine who can access any file or directory and whether it can be edited or deleted. There are three types of access for …

Learning the Command Line – File System

snow

Last time we learned how to list files, now let’s see where those files are. All your files reside on your hard drive, either internal, external or SSD. These drives have files and folders scattered throughout the drive but most are in certain places and are required for the system to function. Moving or deleting certain files or folders can cause your system to malfunction or even not boot. Best practice is if you don’t know what it is, leave it. The beginning of your drive, called the root, is …

Learning the Command Line – Listing Files

Terminal_—_bash-ls-1

This is the second article in the command line series. The first article by vansmith can be found here: http://www.mac-forums.com/blog/learning-the-command-line-part-one/ This time we will be discussing file management commands. Some of these commands might look strange to you. That’s because most Terminal commands have the vowels and sometimes consonants removed to make the command shorter. For instance the copy command is cp with the o and y removed. Obligatory warning: Please be careful when working on the command line. Most commands will not ask you “Are You Sure?” like a …

Mac-Forums Investigates MacKeeper

MacKeeper Default View

Update (July 27, 2013): Grammar/spelling errors corrected and a short section about Mac-Forums’ relationship to the product was added. Introduction One of the persistent questions around the forum has to do with a piece of software called MacKeeper. A cursory scan of the forum will paint in the minds of new members a confusing picture. On the one hand, many of our community members argue against it, describing it as bad, harmful, problematic and, my favourite, akin to snake oil (thanks to chscag for that one). On the other, the software is a permanent …

Clamshell Mode Performance Issues: A Myth?

info_chart

Background A while back, I remember hearing a theory floating around that running a Mac in clamshell mode forced OS X to throttle the processor to save on heat. There is a tiny bit of anecdotal evidence to support such a claim (here) which ultimately suggests that something about clamshell mode might be slowing down the performance of the machine. As someone who runs his machine in clamshell mode quite frequently (the compulsive neat freak in me loves that it saves me space on my desk), I decided to put this …
