Inserting new line in echo command

Out of curiosity and the perfectionist in me, I “had” to print a line of text in the output inside a BASH shell script. I didn’t really want to split them into multiple echo statements since it’s a waste of space and actually harder to read for me. The first thing I tried was:

> echo “Line1\nLine2″ # Line1\nLine2

That clearly didn’t work out so well… so I thought maybe my Mac (OS X 10.5.7) likes ‘\r\n’ more:

> echo “Line1\r\nLine2″ # line1\r\nline2

Still nope! As I found out later on though, not all versions of echo supports backslash escape characters. A quick look up in the MAN page for echo revealed that I needed to pass in the -e option in order to enable this capability:

> echo -e “Line1\nLine2″

Line1
Line2

TADA! Third time is the charm!

One Giant Robot After Another

Changed from ‘Code Monkey’ to ‘One Giant Robot After Another’! Where did I get the inspiration from? Well, I initially really liked ThoughtBot’s blog, Giant Robot Smashing Into Other Giant Robots, but copying them would be boring and probably not make those guys very happy. However, I recently came across some articles about a couple of giant robots being built in Japan on Gizmodo: a giant Gundam (done building) and Tetsujin (under construction). For the lack of better naming schemes, I just took the sequential order of how the robots are built as the new name, literally ‘One Giant Robot After Another’.

Manually Downgrading iPhone OS

If for some reason you’ve ran into a situation where you want to downgrade your iPhone’s OS but iTunes just won’t comply with your command, I’ve found that there’s an easy way to force the action:

Connect your iPhone to the computer and have iTunes opened
Hold down both the power and home buttons until the iPhone disappeared from the devices list in iTunes
Release the power button but continue to hold down the home button until iTunes detects there’s a device in recovery mode
Hold down shift on Windows or option key on the Mac while pressing Restore in the iPhone screen in iTunes to initiate a restore to the desired version of firmware

Finally finished setting up my site and basic wordpress installation! It took me awhile just to settle on the combination of hosting and domain registrar. In the end, I decided to go with Site5.com for the hosting and GoDaddy for domain. Site5 is currently (and has been) promoting 25% discount but it’s not hard to find the 26% discount if you look just a little bit harder. The promotion code I used to get the 26% discount was ‘BPJOBBRD’.

So what’s my impression of Site5 so far? Not bad at all actually! I was initially a little suspicious of their offer of unlimited bandwidth and storage as it’s usually a recipe for disaster as hosting companies will try to overcrowd their server with clients just to make up for the margin. However, the highest load I’ve seen so far on my server is a mere 1.5, very respectable considering they claim to have ‘cat /proc/cpuinfo’ reveals they have 8 cores on the machine.
