Is running .sh files allowed (without Rooting Phone)

giga · Dec 30, 2012

Help Please.

When i try this

B4X:

Sub manualstart_Click()

Dim i As Intent    
i.Initialize(i.ACTION_CALL, "file:///sdcard/user/config.sh")    
i.SetType("bin/sh")    
Try       
StartActivity(i)    
Catch        
ToastMessageShow("Cannot start file.", True)
Log(i)
End Try

End Sub

I get the error
(Intent) Intent { act=android.intent.action.CALL dat=file:///sdcard/user/config.sh typ=bin/sh flg=0x20000 }

Thanks for any help.

I tried Phone.Shell

and got this error

java.io.IOException: Error running exec(). Command: [config.sh, /sdcard/user/config.sh] Working Directory: null Environment: null

I don't think that it is possible without rooting the phone.

Erel,

I have seen two other programs that use rsync. One immediately downloads the binary and claims not to need root.

Do you know how is this possible?

Thanks again.

How do you know rsync is not running?
You can type each line of the script in terminal emulator to test it line-by-line.

Thanks for the reply thedesolatesoul.

What directory are you running it from? Are you in the same directory as the executable? Try

B4X:

./rsync

instead of

B4X:

rsync

Thanks,

In Terminal I cd to mnt/sdcard/rsync(where I placed rsync binary)

tried ./rsync

permission denied :sign0148:

thedesolatesoul · Jan 3, 2013

Is it executable? Can you check the permissions on it with:

B4X:

 ls -ltr

If it is not you can make it executable with

B4X:

chmod +x rsync

:BangHead: Sorry to take up your time.

ls -ltr returns unknown option -t Aborting
chmod +x rsync returns Bad Mode

Also is I try su

i get UID 10049 not allowed to su

Then try:

B4X:

ls -l

and

B4X:

chmod 777 rsync

(this will make it read/write/execute)

I can do ls -l returns a directory list

chmod 777 rsync. returns Operation not permitted.

Thanks for your diligence :sign0013:

What output does this return:

B4X:

ls -l rsync

If chmod isnt working then I am not sure how to make the file executable.

giga · Jan 3, 2013

ls -l rsync returns

the file name rsync, this is a binary file. Can I push a rsync.exe file into the sdcard. I was told that android can't run .exe files.

ls -l should also return the permissions in the form of rwxrwxrwx or something like that. If there are no 'x' in the permission then the file is not executable.
Android cannot run windows binaries (.exe).

giga · Jan 4, 2013

ls -i rsync

Yes the line returned is:

----rwxr-x system sdcard_rw 308024 2013-01-02 23:04 rsync

but chmod wont change it because user permissions, in terminal i could probably change it through ADB but that wont be possible for each phone this will used on.

Thanks thedesolatesoul for you efforts. the other option i have is to send the sh to a app like terminal and use it as a initial command.

B4X:

Try
Dim isy As Intent
Dim new As PackageManager
 
' application must declare jackpal.androidterm.permission.RUN_SCRIPT In manifest 
isy.Initialize(isy.ACTION_MAIN, "")
isy = new.GetApplicationIntent("jackpal.androidterm.RUN_SCRIPT")
 isy.putExtra("jackpal.androidterm.iInitialCommand","/mnt/sdcard/config.sh")  
If isy.IsInitialized Then
StartActivity(isy)
 End If
   Catch
  ToastMessageShow ("Failed to launch app! Is it installed?", True)
  Log(isy)
 End Try

but i get Failed to launch app! Is it installed because B4A doesnt like RUN_SCRIPT at the end of androidterm. if i take it off the other app loads. :sign0148: p.s i also declared it in the manifest.

thedesolatesoul · Jan 4, 2013

Make sure you added the correct permission in the manifest.
Your code should be:

B4X:

Dim isy As Intent
 
' application must declare jackpal.androidterm.permission.RUN_SCRIPT In manifest 
isy.Initialize("jackpal.androidterm.RUN_SCRIPT", "")
isy.putExtra("jackpal.androidterm.iInitialCommand","/mnt/sdcard/config.sh")  
StartActivity(isy)

Dont use Try/Catch for now, so that you can see the errors/exceptions in debug.

giga · Jan 4, 2013

I think i added it correctly to the manifest.

I added this line.

B4X:

<uses-permission android:name="jackpal.androidterm.permission.RUN_SCRIPT" />

I will remove the try and catch

Thanks

B4X:

isy.Initialize("jackpal.androidterm.RUN_SCRIPT", "")
isy.putExtra("jackpal.androidterm.iInitialCommand","/mnt/sdcard/config.sh")

returns permission denied
