Over at xsellize.com, the user lll2for3lll, who posted the language file script there and zipped it for download, reported that the long version has been downloaded 2,834 times and the short version 3,421 times, for a total of 6,255 downloads from the xsellize forum alone. I think that only counts the latest version that was uploaded there in March.
I've also had 15,000 hits to that one page on this blog. Then there are people who have gotten it from other forums, the two or three places where it's been translated into other languages and the people who tell me they've ran it on 30 phones.
So I'll add a conservative 5,000 people who have downloaded and used the script through means other than xsellize.
Users usually report that the script deletes 4,000 to 5,000 language directories, but I'll use a more conservative figure of 3,500 because I never had a lot of apps installed and that's what it deleted on mine.
So from those stats, I'm going to go out on a limb and say that I'm responsible for deleting over 40 million directories from iPhones all over the world.
If I remember correctly, there are usually anywhere from two to five or more files in those directories. If we assume a conservative 2.5 files per directory, that's 100 million files.
I'm like a virus.
In reality, I just wrote a script that a few thousand people used, which isn't a big deal, but it's kind of humbling to think I did 100 million of anything. If I had a dollar for every file deleted...

N1 Blog
For anyone who may be interested, I've finally started a blog for the Nexus One called A More Common Hades.

Nexus One
I did it. I bought a Nexus One. I've only had a few minutes to play with it so far and my initial impression of the interface is that it makes the iPhone feel clunky and boring. I don't know if it will be an iPhone killer, but there's a lot to like about this phone.
I plan to continue this blog because I enjoy hacking around on the iPhone. I'll probably start a different blog for the N1.
Taken with my iPhone. I'm going to go out on a limb and say the N1's 5MP camera with flash could probably have done better than my old 3G.

Script for looking up language codes
Shhh, don't tell anyone but I've made a secret post. It's a simple script to look up language codes, but it's 1100 lines long. The script is one simple grep command, the other 1100 lines are just languages and codes.
I made the post date Jan 1 2009 so it would go straight to the archive and not take up the front page. It can be found here.
It may be useful to anyone running my iPhone language deleting script who runs across an unknown language code.

whereis
Another simple script to replace the missing whereis command on the iPhone.
#! /bin/shToo bad an if statement needs a then statement to go with it. Since ls has it's own output, there's no reason to duplicate it so it's easier to use the ls output and do an empty then command. The result works, but it just looks dumb. Here's a shorter version. It will list all the files. If any are not found, the error goes to /dev/null.
if
ls /usr/bin/$1 2>/dev/null
then echo >/dev/null
elif
ls /usr/local/bin/$1 2>/dev/null
then echo >/dev/null
elif
ls /usr/sbin/$1 2>/dev/null
then echo >/dev/null
elif
ls /sbin/$1 2>/dev/null
then echo >/dev/null
elif
ls /bin/$1 2>/dev/null
then echo >/dev/null
else
echo "$1 not found in /bin /sbin /usr/bin /usr/sbin /usr/local/bin"
fi
#! /bin/shBut that won't give you a "not found" message. So let's take that and put it in a variable. If the variable is not empty, it will echo the variable, which is the non-error output from the ls command. If it ends up empty, the -n test will fail so the && command is skipped and the || command executes.
ls /usr/bin/$1 /usr/local/bin/$1 /usr/sbin/$1 /sbin/$1 /bin/$1 2>/dev/null
#! /bin/sh
test=$(ls /usr/bin/$1 /usr/local/bin/$1 /usr/sbin/$1 /sbin/$1 /bin/$1 2>/dev/null)
[ -n "$test" ] && echo $test || echo "$1 not found in /bin /sbin /usr/bin /usr/sbin /usr/local/bin"

Whatis it, man?
The "man" command is used to read UNIX manual pages and "whatis" gives you a brief description of a command taken from the NAME field of the man page. The iPhone lacks both commands, but these work ok.
man:
whatis:
man:
#! /bin/shI actually like that because it's easier to grep the output, but adding a pipe to "less" more accurately approximates the real command. You could probably roll the grep into the sed command, but that's one of those things where I don't mind spending an extra one-thousandth of a second execution time to keep from having to craft a better sed one-liner.
links -dump http://unixhelp.ed.ac.uk/CGI/man-cgi?${1} | grep -A 1000 NAME | sed 's/^[ \t]*//'
whatis:
#! /bin/shLet's test it.
links -dump http://unixhelp.ed.ac.uk/CGI/man-cgi?${1} | grep "\- " | head -1 | sed 's/^[ \t]*//'
# whatis ifconfigClose enough.
ifconfig [] (8) - configure a network interface
# ./my_whatis ifconfig

Final script for deleting iPhone language packs
This will probably be the final script for deleting language packs on the iPhone. As I have said before, it is a pain to keep up with the ever-changing languages. This started out as a script I threw together in an hour or two just because I was curious if I could write a self-referential script that listed the languages and allowed people to pick the ones to remove, but has become something popular that needs maintaining, and the developers who create the language packs don't seem to have any guidelines for naming them. As the languages changed, the older script got longer and asked the user more and more questions. This one changes that and makes it easier for me to maintain.
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:
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.

Using ssh to bypass iPhone's launch timeout on the fly
I don't think this particular method is of much use, but it may be worth knowing in a pinch.
The iPhone has a launch timeout built into the system. When an app launches, it isn't supposed to start processing data right away, it is simply supposed to load whatever it needs then make a C++ call to the system saying it finished launching. This call is aptly named applicationDidFinishLaunching. If the system doesn't get that call, it assumes the app failed to launch and kills it.
The same thing happens when you launch a shell script from a SpringBoard icon. This script will not work:
Some jailbreak apps have a way around this. I emailed BigBoss a few months ago and asked if he knew of a way around the launch timeout with a script, and he pointed me to the method SBSettings uses. SBSettings does not actually launch itself, it instead uses a small shell script to launch the real SBSettings executable:
Unfortunately, I had already tried this and could never get it to work with a shell script. I've also tried every other method I could think of to background a script such as using the standard "&" tacked on to the command or trying the disown command. These would probably work in MobileTerminal, but nothing seemed to work when launching a script from SpringBoard.
You may be able to use launchd to run a longer script, but I wanted to do it on the fly. I only had one long script I wanted to use and simply gave up on it and forgot about it until an unlikely answer came to me while working on an unrelated problem. Why not see what happens when you ssh in to localhost and run the script?
Well, you can't simply ssh in and run the command or the ssh pipe will stay open. This is a feature of OpenSSH used to avoid a race condition. To background it, you have to redirect sdtin, stdout and stderr to a file or, as I used here, to /dev/null.

#! /bin/shThis is meant to pop up a notification every ten seconds but after approximately 18 seconds, the system kills it because it did not receive the applicationDidFinishLaunching call.
uiopen start
sleep 10s
uiopen ten
sleep 10s
uiopen twenty
sleep 10s
uiopen thirty

SBSettings does not actually launch itself, it instead uses a small shell script to launch the real SBSettings executable:
SBSettings=$(dirname "$0")What this does is pretty simple. The script uses the first line to find itself on the system, the second line launches SBSettings, which it expects to find in the same directory. It launches with the exec command, which replaces the current shell with whatever exec executes.
exec "${SBSettings}"/SBSettings

slogin -i ~/.ssh/KEY localhost '/Applications/test.app/test_ </dev/null >/dev/null 2>&1 &'To my surprise, that actually works. This command can be put in /Applications/test.app/test and launched from SpringBoard. It will then ssh to localhost and successfully launch and background test_, which can run as long as it wants.

Forum grabber
I use various methods to visit forums. If I'm at my computer, I use a browser, obviously. On my iPhone, I use a forum app named Kaytri a lot, but I visit a couple of forums that have very low thread counts and I thought it would be nice to get a "daily digest" of all the new subjects to see if there is anything interesting.
This can be done pretty easily with links or lynx and their -dump switch, but they both split the subject line and have so much additional output, that it was simpler to start from scratch.
Starting with wget spitting out the raw html in quiet mode, I looked at the code to a couple forums and found that most use "thread_title" in their html, so it's just a matter of grepping "thread_title" and filtering out the tags with sed and (optionally) aligning the text to the left with sed also.

wget -q -O - [FORUM] | grep thread_title | sed -e 's#<[^>]*>##g' -e 's/^[ \t]*//'
One possibility for using this is to get a daily forum update by putting the output in a file, comparing it with an older version, and sending yourself only the new content.cd /path/to/tmpfile/directoryThis can be useful for both fast and slow paced forums to watch for new subjects, then you can decide whether to visit them and jump into the argument or not.
[wget command] > .b
newcontent=$(cat .b | grep -v -f .a)
# if there is new content, do something with it
# email it to yourself, send a push notification, etc
[ -n "$newcontent" ] && [do something with $newcontent]
mv .b .a
