Although many things look the same, this version has many changes. There are some performance improvements, although they may not be evident since it's an interactive script. It will also end itself if it doesn't find anything to delete and, overall, it just "flows" better.
The most noticeable improvement is the interaction with the user. It will only ask about the languages which it finds on the system and it will only ask once for each language. So if it finds 6 differently named Spanish directories and 2 Germans, it will only ask if you want to delete Spanish and German. The user no longer has to answer yes or no for every single code for every single language.
It has 35 languages built in because that's what Apple says the iPhone supports, but most people won't have that many installed. I've included every language code I've found over the past couple of months for those 35 languages as well as every possibility a total of 270. It will also present unrecognized languages to the user if that language is not found in those 270.
I will no longer maintain my original script as this one does everything that one did and does it in a way that is less hassle for the user.
After this is out for a week or two and I make sure there aren't any bugs in the script, I'm considering my foray into iPhone languages finished. I will update this script with new languages and it would help greatly if people send me their log files (the info is in the script) but I simply don't have the time to do anything more.
My stripped down version for deleting everything except English will never be obsolete (unless Apple changes how languages are used) and, if that's the only language you want, would be simpler to use and will remove every language except English whether it is recognized or not.
Requirements.
Jailbroken iPhone/iTouch OS 3.x. Or 4.x. Several users have recently used this successfully on OS 4.0.
This script uses basic BASH shell builtins and unix core utilities. Both are installed by default when you install MobileTerminal on the iPhone. It's possible that you can install them separately, I don't know, but I suggest installing MobileTerminal and also recommend using MobileTerminal to execute the script and iFile to get the script on the phone.
I would love to use more powerful tools like sed or awk and cut this script down to a fraction of the length, but I'd rather have it use minimal dependencies.
How to use.
View this page on your iPhone.
Copy everything from "#! /bin/sh" to "# end of script"
If you have Safari downloading enabled on your phone, click here and download it directly to your phone. (having trouble with mediafire, please redownload if you downloaded in the past few minutes)
Or, create a new text file on the phone with iFile. You can name it anything, but I will use langpack2.sh as an example. You can do this anywhere, but for simplicity, I suggest creating it in /var/mobile (a.k.a. /private/var/mobile)
Paste the script into the text file and save it.
Open MobileTerminal, cd to the directory where langpack2.sh is located and type chmod 755 langpack2.sh and hit enter, then type ./langpack2.sh to run it.
There are other ways to do this but I'm a Linux guy and I don't have a Mac and use Windows about twice a year so I can't recommend anything else.
Windows can screw up the formatting of the text if it isn't transferred to the phone a certain way and I'm not going to research how to do it. I've never touched a Mac, so I can't help there either. One thing we all have in common is the phone and the two iPhone apps iFile and MobileTerminal are the recommended way to run this script. Using this method, it can be downloaded and executed while you're walking down the street, no computer needed.
Linux users should have no problem saving it on their computer, ssh'ing it to the phone and running it there. I did most of the testing in a Linux terminal with ssh, but MobileTerminal is still the one foolproof way to run it.
Another method to get this script using nothing but the phone is to install lynx from Cydia then run this command:
lynx -width=500 -dump http://tinyurl.com/356wmua | grep -B 182 "end of script$" > langpack2.2.shThat will grab the text from this page and put it in the file called langpack2.2.sh.
You may also be interested in this script for identifying unrecognized language codes.
(May 17) I've gotten some hits from a couple of sites which have translated the text of the script to German and Hungarian, which may be useful for anyone speaking those languages.
(Dec 29 2010) Several users have reported that the script fails to recognize vi.lproj. This is Vietnamese and can be deleted if you don't need Vietnamese. The script looks for vi.lproj and worked fine for months, but started missing it all of a sudden. My iPhone is a gaming device for my daughter and is still on 3.1 and I have no plans to update it to the latest firmware so I will probably never fix this problem.
