Shell Programming and Scripting

1. What I am doing?
Building a DOS .bat file that will root my Droid 2 phone using adb commands in the .bat file. (Just for the fun of it and to help me learn "stuff".)

2. Problem:
Here are the problem steps to accomplish this task manually in an adb shell:
adb shell (Prompt is $)
cd data/local/tmp
chmod 0755 rageagainstthecage-arm5.bin
./rageagainstthecage-arm5.bin (then WAIT!!)
Ignor remarks in parentheses.
(there are many other steps, but they all work no problem in the .bat file.)

In the .bat file this is what I have:
adb shell "chmod 0755 /data/local/tmp/rageagainstthecage-arm5.bin"
echo Installing Rageagainstthecage
adb shell "cd /data/local/tmp/;./ rageagainstthecage-arm5.bin"
pause
adb wait-for-device
adb devices

This line: adb shell "cd /data/local/tmp/;./ rageagainstthecage-arm5.bin" looks like it is working because the .bin file prints about 7 lines telling you to wait till you reset back into your dos environment.

In manual mode the cursor blinks for a few seconds, then the dollar sign comes up, then after a few more seconds the prompt changes to C:\users\a at which time you go into a shell get the # cursor, mount the system rw, push more files to directorys on the phone and change permissions and finally mount the system ro.

In manual mode after the $ comes back the phone will reset and reboot.
In the .bat file I get no $ (well, I can not see so that is why I placed the pause in there, but if the pause is working I have already exited the shell and the next command executes and everything after that fails because I can not mount rw,
because the rage....bin either has not finished or did not run correctly because the phone does not reset/reboot.

If it works manually, it should work in a script, if ya know what to "say".

I have goggled around for 3 days and learned about "source" ".script", ". ./script and other things that are over my head like: cd "$(dirname "$(type -p "$0")")".
I someone could explane the "$(dirname "$(type -p "$0")")" ??

As a matter of fact, most of the errors say "syntax error 1.word expected expecting )")" .
Or when I use source I get "Permission denied"

So do I need to add a semicolon with the chmod command between the cd bla bla and the ./ or source.

I am required to have my phone in "PC Mode" and "USB debugging enabled". Both are set properly.

Thanks for any advice.

I got it and now everything works fine!
adb shell "./data/local/tmp/rageagainstthecage-arm5.bin & sleep 300;kill $!"
echo Reconnecting in 20 sec...
adb kill-server

adb start-serve

Thanks for keeping us informed and giving your solution... (changed the title...)
