UNIX for Dummies Questions & Answers

The way this works from the command prompt is:
___________________________________________
cd /data/local/bin
chmod 0755 file.bin
./file.bin
_______________________________________________
How do I make this happen in a script. The file must be run in its directory but I can not get the script to actually change directory.
At script execution cd works but the other two commands "file not found"

I can make it look like the file is being executed if I make the script read:
cd /data/local/bin;chmod 0755 file.bin;./file.bin

It will not run properly because it is really running in whatever directory the script is in.

Code:

 /data/local/bin/file.bin

will run the file named file.bin.

Is there a reason for the .bin filename extension? It is unusual in UNIX to name executable files that way, except for really old UNIXes like DGX.

No, I get the same result. The file looks like it is running but...

It is a real .bin file designed to root a phone but it must be run in that directory. Command prompt works flawlessly, but not from a script.

I am using Windows 7 with the Android Debug Bridge. The phone operates under a Linux system, the adb gets you in a shell on the phone where you can do what you want or know how to do. If the .bin files works you know it worked because the phone will reset. I do not get that reset from the script.

I am writing a DOS batch file that will root and unroot the phone. That means that I have write 'adb shell "do something;do something else" '

I just can not make it go to another directory and then execute commands, they all get executed from the "/" directory.

Thanks

I finally got it an hour ago:
adb shell "./data/local/tmp/rageagainstthecage-arm5.bin & sleep 300;kill $!"
echo Reconnecting in 20 sec...
adb kill-server

adb start-serve
