Shell scripting is wildly useful and a powerful way to manipulate a lot of files and to automate behind-the-scenes tasks in Mac OS X. This guide is intended for Linux users but the Bash shell is also used in Mac OS X, and as far as I can tell everything in this bash shell scripting guide works the same across the two platforms. Before checking out the guide you might want to check what shell you are using in Mac OS X by typing the following in the Mac Terminal:

echo $SHELL

Something like /bin/bash or /bin/tcsh will be reported back to you, obviously this Bash scripting guide only works for the Bash shell. If you need to, you can change the default shell rather easily in the Terminal preferences, but Bash has been the default shell since 10.3 and continues to be in Snow Leopard.

If you’re looking for more, a much more advanced and complete guide to Bash scripting is available here:

Advanced Bash Scripting Guide

And if you really want to dive into shell scripting, a good book like Pro Bash Programming: Scripting the GNU/Linux Shell will do you wonders.

We’ve long been fans of the Dell Mini 10v for Hackintosh purposes, it’s small, quick, attractive, and can be obtained for surprisingly cheap in the $200 range. It looks like the rest of the blogworld is catching on to this little beast of a MacHack Netbook, Gizmodo has an excellent write up on installing Snow Leopard on the Dell Mini 10v, it’s definitely worth checking out. I’d highly recommend buying a refurbished unit from the Dell outlet to save yourself some serious cash (a friend got one for $189!), so check out our guide to a cheap Mac Netbook with the Dell Mini 10v, and then follow the Gizmodo guide to get it all up and running with Snow Leopard. For $200 you can’t go wrong!

As you may know by now, MAMP is a really useful instant webserver for your Mac that requires practically no setup or installation, you run the app and click “Start” – yes it’s that simple.

I use MAMP a lot for local web development and really like it, it’s probably the easiest way to develop locally with something like WordPress. I was going to write a full article on setting up MAMP and WordPress, but TUAW beat me to it! So rather than re-writing the wheel, let’s take a look at TUAW’s simple walkthrough on getting WordPress setup under MAMP:

TUAW: Getting Started with WordPress & MAMP on your Mac

If you’re still a little confused or want a more thorough walkthrough, check out this one at labs.dariux.com:

Labs.Dariux: Install and Run WordPress Locally with MAMP

If you do any kind of web work or development, you really should check out MAMP!

Happy web devs, enjoy your local WordPress setup.

If you’re a web developer you probably do a fair amount of development on your local machine using either the built-in Mac OS X Apache server or, in my case, something like MAMP. Because a local web server like this is really handy for testing this, you can make your local development life a bit easier by setting a local domain, and we’ll show you how to do that.

Did you read that correctly? Your purchase of a Mac Mini becomes free after 2 years due to it’s energy efficiency. Yea, it sounds ridiculous I know, I didn’t believe it either, but recent Mini owner CJ Gill compared his months of electricity bills with a Mac Mini to the months before one when he had an HP Pavilion desktop PC, and the monthly electricity savings of roughly $20 are going to pay for his Mac Mini in about 2 years. Check out the power bills in this chart:

When someone first sent me the link to this blog post titled “Free Mac Mini! No Strings Attached!” I figured it was yet another one of those pyramid scams where you sign up for 50 offers and you get your friends to sign up for 20 more and then you get a free burrito that eventually morphs into a Mac Mini after you sell 300 more offers. How awesome is it that Apple’s claim of having the worlds most energy efficient desktop translates into significant cost savings, enough so that after a few years depending on the Mini model you buy, it becomes free! Simply amazing. I know what my next Mac purchase is going to be!

You can buy the latest Mac Mini for $579 at Amazon and it includes free shipping.

Ever wanted to play music while you’re working in the command line? Maybe you want to play a podcast from the command line on Mac?

With the command line tool ‘afplay’ you can do just that, you can play practically any audio file format, whether it’s M4A, AAC, MP3, WAV, AIFF, or whatever else is on your Mac, and you can start the audio right from the Terminal.

From the Terminal, if you want to quickly find out what the largest files are in a directory, try this variation of the ls command:

ls -lShr

the l flag will display the items in a list, the S flag sorts by size, and h makes it readable in MB/GB (human readable), with r reversing the report order so that the largest file is the last on the list and thus right above the returned command prompt.

If you want the largest file in a directory of a certain type, simply specify the file type with a wildcard to show all files fitting that description:

ls -lShr *.zip

Try it out with any filetype *.mp3 *.mov *.wmv *.psd , etc

It really drives me nuts when files can be of the same kind but different type open different apps, I want to open all my images in Preview and all my video files in VLC. You can make Mac OS X open every file of a certain format type with a certain application by changing the file association from the Finder. We’ll show you how to change the file type association in Mac OS X so that you can set file kinds to open all in one application.

Users can get detailed wireless information from the Airport menu by holding down the “Option” key when clicking the menu icon. The ability to pull the Security type and Channel directly out of the menu is a big plus for me, but the other information should certainly be useful when troubleshooting a WiFi problem too.

This is a Snow Leopard only tip, and I thought we had covered it here at OS X Daily but apparently not… so thanks to TheGraphicMac‘s post on the matter to remind me to share it with you all (note the image attached to this post is from TheGraphicMac too).

The Lenovo S10 may just be the easiest hackintosh netbook option to run Mac OS X, according to a guide on the site Tech-Chimp. The guide is so short and so simple, it’s almost hard to believe, this is basically what it says:

* Upgrade the Lenovo s10 firmware
* Using this tool, prepare an 8gb USB key to be the install device
* Boot the Lenovo off of the aforementioned USB key
* Install Mac OS X Snow Leopard, as if on a Mac, but on the Lenovo
* Boot Mac OS X on your Lenovo S10

What?? That’s it? I don’t have a Lenovo S10 to test this on, but if this is true, that is a truly amazingly easy install. They even say that sleep works on some of the models. Here at OS X Daily we usually opt for the turning the Dell Mini 10v into a Hackintosh Netbook because it’s so cheap ($199 refurbed on the Dell Outlet just last week) and it also is pretty easy to install on… but the downside to the Dell Mini 10v hackintosh is that Ram is very obnoxious to install. If we had the ability to test the Lenovo S10 guide from Tech-Chimp for Hackintoshing, it very well may get our hackintosh recommendation, even though it comes at a heftier price tag ($300 according to Tech-Chimp).

Want to quickly turn off all of your Mac’s displays? Hit Shift+Ctrl+Eject and all screens will go black instantly. Nice huh?

Some iTunes music comes with DRM, but you can use an iTunes trick to remove DRM. Note this should only be used if you own the actual rights to the music, or if you are allowed to remove DRM by the rights-owner.

DRM iTunes songs usually have an .m4p file extension. But this trick basically allows you to convert .m4p to .m4a.

On a Windows PC recently I ripped a CD only to find out that it was converted as WMA rather than MP3. In Windows this isn’t a big deal, you just open the files in iTunes as usual, but I wanted them on my Mac, easy right? Well for some reason Apple doesn’t allow Mac iTunes to convert WMA files to MP3 audio so I was a bit frustrated, to make matters worse a typical google search will net you a ton of ancient apps that like to crash a lot, or ones that try to charge you some-odd dollars to convert an audio file… forget that!

Yes you read the right. The iPhone is the fastest growing consumer electronic product in history. TechCrunch states:

Its adoption ramp is even steeper than videogame consoles including the Nintendo Wii, Nintendo DS, and Sony PSP. The original iPod and Blackberry aren’t even in the same league.

If you’re in the US and have AT&T as your iPhone provider, you may frequently hear complaints about the speed of the AT&T data network, well that’s because it is 50x – FIFTY times! more than it was 3 years ago Wow again. I included two charts from TechCrunch that really show the explosiveness of the iPhone growth and it’s strain on the AT&T network, I’m just blown away by this.

Mac users can issue a defaults command string to force Safari to open targeted new window links into new tabs instead of those new windows. This is handy if you open a lot of links that would usually launch a new window but would rather send them into easily managed tabs instead.

You can enable MMS on the first gen iPhone 2G (you know, that metal one), but it requires a little bit of hacking. This is pretty great news if you have one of the first iPhones but you feel left out by the MMS intro passing you by. Here are the instructions reposted from Lifehacker.com who reposted it from Hackint0sh.org (blog regurgitation at it’s finest!):

1. Backup original CommCenter (goes without saying…)
2. Replace CommCenter in: /System/Library/PrivateFrameworks/CoreTelephony.framework/Support/ with a patched one.
3. Chmod the new CommCenter to 755
4. Open /System/Library/CoreServices/SpringBoard.app/M68AP.plist and insert a true boolean value for “mms” under capabilities

It goes without saying that you should backup your phone, and also you should probably be pretty tech-savvy to go digging around your first gen iPhone’s MMS software guts. Read the full guide on the hackint0sh.org forums before diving in, it looks like it’s largely untested which should cause it to warrant even more due diligence than usual. BTW when did the first gen iPhone start being known as the iPhone 2G?

I always put iTunes into mini-player mode to conserve screen real estate, so I was pretty annoyed when iTunes 9 took away this feature when clicking the green resize button in the iTunes window. Thankfully getting it back is very easy but it’s an extra step, option-click the green maximize button to enter into the iTunes 9 mini player mode.

Note: as one of our readers points out below, the behavior of the green button was changed in iTunes 9.0.1 update, you no longer need to option-click if you upgrade to the latest version.

So, that’s iTunes 9, but it’s different again in iTunes 10, iTunes 11, and iTunes 12. Apple likes to keep everyone on their toes! When iTunes 13 and iTunes 14 comes out, it will surely be different again too…. maybe!
