How to execute Shell script in android

[Vikas KM]

Hi All,

I want to execute a shell script in android

*************** SHELL SCRIPT ********************

 if [ ! -d "/sys/devices/platform/ehci-omap.0/usb1/1-2/1-2.4" ]; then
    if [ -d "/sys/devices/platform/ehci-omap.0/usb1/1-2" ]; then
        NUMINTERFACE=`cat /sys/devices/platform/ehci-omap.0/usb1/1-2/bNumInterfaces`
    fi
 fi

********************************************************

That is based on the path if it exists, I want to run another script...

But i m unable to run the below script any idea what might be wrong?

I have root shell...


# sh ($PATH)/script_name.sh   Command i m using.

You can add this as part of your init scripts

ex: add it in init.rc or some other init scripts. it should work.

thanks

Various things... but it's likely not relevant.

Take a step back and tell us what you are trying to accomplish.  It appears you are trying to create a shell variable or modify an environment variable based on the existence of a file.  Unless you are doing system programming (in which case you should be asking on android-porting) that's note really an android way of doing things and would be pointless anyway as the variable would not propagate anywhere.  On android, whatever app needs to know this information should be finding it out via an android-style ipc or property mechanism, or simply doing the checking itself.

Install busybox and it does most of the scripts, Google it and you will see what are the steps.

By itself what you have posted accomplishes nothing, so the fact that it runs is of little importance

As I said before, tell us what you are trying to accomplish, and we can discuss alternatives - writing in a way that will work with toolbox, writing a small executable, etc...

You might try browsing around on the device and see if you can find how things similar to what you want to accomplish are accomplished.

Hi,

If you're using it in init, perhaps you can check init.goldfish.rc and
system/etc/init.goldfish.sh? It's there in every build and is an
example of shell scripts.

Perhaps you are missing a shebang?
