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

This code works correctly:

B4X:

Sub Activity_Create(FirstTime As Boolean)
   Dim p As Phone
   File.WriteString(File.DirRootExternal, "1.sh", "#!/bin/sh" & CRLF & "echo test")
   Dim out, err As StringBuilder
   out.Initialize : err.Initialize
   p.Shell("sh", Array As String(File.Combine(File.DirRootExternal, "1.sh")), out, err)
   Log("out: " & out)
   Log("err: " & err)
End Sub

Note that you should post the full error message from the logs (you can copy with right click).

Thanks Erel,

Does it require ROOT?

No.

The Code MASTER Erel Stricks Again!! GOOD JOB:sign0060:

I am getting Permission Denied in the Err. log

But I got much farther than Before. I will research this more.

BIG Thank You Erel. Happy New Year to YOU.

Erel,

i used the code you recommended and got permissin denied. So i tried the su code http://www.b4x.com/forum/basic4andr...nning-shell-commands-superuser.html#post39820

B4X:

Sub manualstart_Click()

Dim prs As Phone
Dim Command, Runner As String
Dim out, err As StringBuilder
Dim Result As Int
out.Initialize : err.Initialize
Runner = File.Combine(File.DirInternalCache, "runner")
Command = File.Combine(File.DirRootExternal & "/config", "config.sh")
File.WriteString(File.DirInternalCache, "runner", "su < " & Command)
Result = prs.Shell("sh", Array As String(Runner), out, err)
Log("out: " & out)
Log("err: " & err)


End Sub

and i am getting

err: su: uid 10044 not allowed to su

i also tried root,user and get

err: root: permission denied

Any Ideas would be great. Thanks again to all.

'su" might not work on certain devices, look at THIS thread.

Different devices do not have all the available commands.

giga · Dec 30, 2012

Thanks for the reply. I am using the emulator, Not an actual device yet. Strangely If i use another program to run the same script it works like (BusyBox). But not in B4A :BangHead:

Erel · Dec 31, 2012

i used the code you recommended and got permissin denied

Can you post the exact message?

'su' requires root.

I've tested the code I posted of Galaxy Nexus and it works fine. Though such shell commands may not run properly on all devices.

This is the exact error message in the log.

err: su: uid 10044 not allowed to su

giga · Dec 31, 2012

Erel,

As far as I can tell, I got this one to work without the su .

B4X:

Sub manualstart_Click()

Dim prs As Phone
Dim out, err As StringBuilder
out.Initialize : err.Initialize
prs.Shell("sh", Array As String(File.Combine(File.DirRootExternal & "/config", "config.sh")), out, err)
Log("out: " & out)
Log("err: " & err)

End Sub

The problem was in the config.sh I used writeline instead on write to create the sh which caused new lines for each word vertically.

I am not getting the error now, this is the log now.

out:
err:

But I can't see if the sh(script) is running.
Is there a way of showing a DOS Shell or Android Terminal to display the progress????

Thanks for sticking with me on this.

NJDude · Dec 31, 2012

You could install something like a Terminal Emulator to see it running.

Good Idea, At this stage I will try that at least for testing.

I was hoping there was something included in Android that I could use as GetApplicationIntent.
I could send a script to and show the progress on the screen.

Thanks NJDude for the suggestion.

I tried Terminal Emulator per their instructions here: https://github.com/jackpal/Android-...ng-Android-Terminal-Emulator-from-another-App

But I cant get it to work with jackpal.androidterm.RUN_SCRIPT

It does come up jackpal.androidterm (without RUN_SCRIPT) :sign0148: but nothing but SOM(start of message)

B4X:

Sub manualstart_Click()
Try 
 Dim Intent1 As Intent
 Dim pm As PackageManager
 Intent1 = pm.GetApplicationIntent("jackpal.androidterm.RUN_SCRIPT")
 Intent1.AddCategory("DEFAULT")
 Intent1.PutExtra("jackpal.androidterm.iInitialCommand", "echo 'Hi there!'")
 If Intent1.IsInitialized Then
StartActivity (Intent1)
 End If
   Catch
  ToastMessageShow ("Failed to launch app! Is it installed?", True)
 End Try 

End Sub

I also added to the manifest

B4X:

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

No luck. Any help, ideas are appreciated.

The Out parameter should show the script output. You can add echo statements in the script to print the output.

So if the log shows the following

out:
err:

Does this means nothing is happening??

Erel · Jan 1, 2013

It means that nothing was printed to the standard output stream or error stream.

Try the example I posted.

Thanks Erel,
The example I tried when you sent it to me works.

out: echo test
err:

I added "#!/bin/sh" to the begining of my config.sh and tried it but nothing happened.

Does this "#!/bin/sh" have to be on a separate line?

:sign0013: to be a pain.

Erel · Jan 1, 2013

Does this "#!/bin/sh" have to be on a separate line?

Yes. Can you post config.sh contents?

giga · Jan 3, 2013

Erel,

I believe the problem is this:

Android does not have the rsync binary by default. I can't put the binary in because it is permission denied on the system/xbin directory.

The script echos entirely in the log, when I put echo in front of the rsync command but nothing happens beyond that.

Thanks, If you have any ideas i would appreciate your expertise. :sign0188:

Sample Code of config.sh

#!/bin/sh
echo rsync -e 192.168.1.10 etc....

Is there another location I can run a binary from??
Can I reference the binary another way in the app??
