Hey, can someone tell me how to create a script to run a terminal command. I looked up google but didn't find any good results.
Open a new file, and write:
Code:
#!/system/bin/sh
your_command
another_command
another_one_xD
Save the file with sh extension, and run your script as follows:
Code:
su #optional, if your script needs root access.
sh yourscript.sh
If you get an error, probably need to grant permissions to your script, so:
Code:
chmod +x yourscript.sh
And try again.
Granting su is
$ su
Correct?
And thanks for the reply :]

Yep
When you set the permissions, you only have to do that once right?
Yes.
I'm trying to build a script to move pics and video from my internal storage to external storage. I have the script made and on my phone but when I run it, I get an error: "failed on /storage/sdcard0/DCIM/Camera/*.jpg" - Cross-device link . Any idea what that means?

Move (mv) only move the directory entry, not the actual data. Because of this, you can not move files from one disk to another (e.g. from internal to sdcard), hence the cross device error. You'll have to copy and then delete the original.

That seems to have done the trick but I have found another issue. When going into multiple directories (/storage/sdcard0/DCIM/Camera) from the script or even the root directory, I get a No Such file or directory error. But I can CD into that directory and manually cp and rm the files. Any idea why that is happening?

You've simply done something wrong. Show us the script.
Here is the script I created:
#!/system/bin/sh
#
#
#
#
#Move Pictures from Internal Storage to External Storage media
cp /storage/sdcard0/DCIM/Camera/IMG* /storage/sdcard1/DCIM/Camera
rm /storage/sdcard0/DCIM/Camera/IMG*
#
#
#
#Move Videos from Internal Storage to External Storage media
cp /storage/sdcard0/DCIM/Camera/VID* /storage/sdcard1/DCIM/Camera
rm /storage/sdcard0/DCIM/Camera/VID*
I put the script in the root directory and run it from there. Its permissions are rwxrwxr

Does /storage/sdcard1/DCIM/Camera exists? Try add:
mkdir -p /storage/sdcard1/DCIM/Camera
... to the script before you begin the copy. This will create the destination(s) in case of non-existent.
Also, your cp and rm command will fail with this error if there aren't any files named both IMG* and VID* in the source directory.

Yes it exists. I can navigate to the directory in Root Explorer. I tried running the script in Root Explorer but it didn't move the two pics i have in the /storage/sdcard0/DCIM/Camera directory to the /storage/sdcard1/DCIM/Camera directory.

You realise that even with pictures in the directory, you'll still get this error from the next operations you try executing on the videos? Still, the script should a) still copy the images, and b) not terminate due to this error anyway (i.e. consider it a warning).
But you say the images are not copied. Quite odd, I'd say.
Add a path to the script (export PATH=/system/bin:/system/xbin plus the places you need), add a test "echo Running" to make sure the script actually is launched by Root Explorer. And add +x permissions for all, even "other". You can also add:
echo /storage/sdcard0/DCIM/Camera/IMG*
... before the first copy. This will show you what files matching your expression.
I'll just manually move them. I was just hoping for an easier way until CM10 is enabled to save pictures to the external SD card.

cannot edit build.prop. i get an error when trying to edit it with es file explorer (there was an error when trying to save this file.)
any help? ive edited it before, but i dont know how. im pretty sure i did it this way but im not sure why its not saving properly this time.
running calk+clemsyn rom/kernel combo.
thanks!
Copy it to another folder edit the copy and then move the edited file in the correct folder.
tried that already, didnt work. got another error
I use Root Explorer to do any editing.
Any other suggestions? I'd rather not have to pay for it

If the build.prop you want to edit is in /system, then you'll have to mount /system read-write before you can modify any files there:
Code:
$ su [I]Become superuser. Prompt will change to '#'.[/I]
# /system/xbin/mount -w -o remount /system
[I]Edit the file[/I]
# /system/xbin/mount -r -o remount /system
You must have the Superuser app from Market and busybox installed on the gTablet for the commands to work. If you can't edit the file in ES File Explorer because of permission errors, copy the file into /mnt/sdcard via the command line, edit it there (or on the PC after removing the card), then move it back into place in /system and restore the old permissions:
Code:
$ cp /system/build.prop /mnt/sdcard/.
[I]a) The build.prop file in /mnt/sdcard should be editable now in ES File Explorer.
Edit the file, then do:
OR
b) Unmount the SD card via Settings > Storage, then remove the SD card and
edit the file elsewhere. Plug it back in, and, after it mounts do:[/I]
$ su
# /system/xbin/mount -w -o remount /system
# /system/xbin/mv /mnt/sdcard/build.prop /system/build.prop
# chown root.root /system/build.prop
# chmod 644 /system/build.prop
# /system/xbin/mount -r -o remount /system
All this is much easier through adb if you have that setup.
Note: Do not type the prompts--the '$' and '#' characters--in; they're just there to tell you what the Terminal screen should look like.

Did you have ES file explorer in Root mode?
In Es file explorer
Settings->Root Options -> both boxes checked, (HiAPK mode for first box)
I usually copy the file to sdcard and modify it, get ES explorer in root mode and copy it back. Do a backup before, in case you mess it up.
I usually use a terminal in su mode for editiing/copying, but that might not be needed.

Try
Code:
/system/xbin/mv /mnt/sdcard/build.prop /system/build.prop
instead of plain 'mv'. The default Android mv command is idiotically implemented. (See this post if you're interested in the details):
http://forum.xda-developers.com/showpost.php?p=13956585&postcount=4
Using 'cp' command instead of 'mv' should also work; this way, you'll also have a backup of build.prop in /mnt/sdcard/.

Thanks, I tried two other applications and they didn't work. Was able to edit with Root Explorer. didnt fix the Netflix playback. Bummer.
***** changing the Nexus S to HTC Vision and samsung to HTC did the trick.
Root explorer will work, and is a great app. Worht the money.
Also, ADB from a PC will work as well. Just install the android sdk and use ADB.
From windows cmd prompts the commands are just adb remount (to remount as root) then "adb pull /system/build.prop" (this will pull it to the sdk platform-tools folder that adb.exe is in) and then edit to your hearts delite.
"adb push build.prop /system/build.prop" to send it back.
I was able to use ES File System by unchecking the Mount File System option in the Root options menu and then rechecking it. I imagine that it forced a remount of the file system in a writable mode.
This worked on our nabi big tab hd24
We now have true multiuser, where everyone has their own login, files, emails, bookmarks, web history, etc; as it should be.
I first did a factory reset, then installed kingo root, then another reset, did the build prop edit this suggested (es file explorer did not work) but build prop editor did....
We now have the nabi big tab hd 24 running as our primary desktop workstation computer...
No we just wish for a room update to be made available with the latest version of Android.

Hey guys
sorry to bother you with this but since I'm not allowed to post in the developer-forum with less than 10 posts I need to ask here:
I'm running Uruk 1.5RC1 on my 101 and want to upgrade to 1.5 stable.
There's a fix I need to apply first and it says:
lease copy this file to /.upgrade/ directory (if it's not there - create it) - and restart your device (during boot you should see for few seconds update message with progress bar)
Click to expand...
Click to collapse
I don't have that directory and if I want to create it it says that it is already there but I don't see it. So I can't access it to paste the file.
Any help?
Thank you very much!
Do you navigate in your folders as Su?(Super User)
Yep, I'm using ES with su-right and I can see the directories.
Except for the one I need I gues...
Do you have a terminal app?
Try something like this:
su
pwd
ls
Then tell me if you see it
I tried terminal and it's not there.
Try to copy the file with terminal
Code:
Su
cd [where you have the file]
Sudo cp [filename] /../.upgrade
This should work
Greets,
Lenn
Thanks. I guess you meant ".update" instead of ".upgrade"?
Anyways, I tried both (without any errors) but there's no update sequence for the fix when I reboot and the update itself still fails.
Try
Code:
su
Cd /../
sudo mkdir .upgrade
With that you create a folder
"Cannpt create directory '.upgrade': File exists"
Why isn't it visible with ES?!
I dont know...
Try it with
Code:
su
cd /../.upgrade
sudo rmdir -r
This should remove the directory, after that try to create a new one like i wrote above
Ok, this is weird now:
"can't cd to /../.upgrade"
When I try .update it says
"rmdir: invalid option --r"

hm... try it without -r (-r is a value to delete also the folders in the directory)
Thanks for your help so far, I appreciate it!
It says:
"can't cd to /.upgrade"
Trying the same command in ".update", which obviously exists (I can acess it) is "invalid option" (with -r) or missing operand (without -r).
I dont have so much linux-experience like other guys around here, sorry..
I think the mrdir command is old.. try it with rm -r
I made it.
Did it again from the scratch with some help from a Linux beginners guide (worked with rm -rf /../xyz/) and updated to 1.5 stable.
Thanks for the help guys!
WARN: For developer only.
attachment is the EXPANDSD script.
Why use it?
So many applications use /sdcard for mass data storage(gameloft, navigation...),
but I9100's internal_sd size is limit to 11G, so we need external_sd's space.
But these applications dosen't know how to use external_sd, old method is hack the apk for external_sd, but this will change apk's signature, and need smali/baksmali to work. My method work in system level, don't need change any apk file.
How to use:
1.make expandsd.ownhere dirctory in external_sd root directory.
2.move internal_sd's directory(for example:/gameloft) to expandsd.ownhere
3.run init_expandsd.sh
Theory：
use 'mount --bind' feature, bind external_sd's dir to internal_sd.
Because the sd card using fat32 partition format, the 'ln -s' command does not work, so the "mount --bind" is the only way to dynamically change the directory content.
Hi mate,

problems when connecting phone to pc
hi,
tried the "mount --bind" in order to try your script.
works fine. the directory contents is shared between the 2 path's,
but i have a problem when i connect the phone to a pc.
when i try to disconnect, the sdcard and external_sd are not
available anymore until i reboot the phone
note: the commands that i have executed are:
Code:
mkdir /mnt/sdcard/external_sd/foo
echo "test" > /mnt/sdcard/external_sd/foo/test
mkdir /mnt/sdcard/foo
mount --bind /mnt/sdcard/external_sd/foo /mnt/sdcard/foo
Can this script be placed in init.d folder for autorun at boot?
Edit: sorry, already answered above: no, it cannot.

Hi,
it's very easy indeed, once you got the point.
I do most of my stuff using an "adb shell" session so I'll post here my steps to get it working.
Also I like simple implementation so my script is the strict minimum needed to mount necessary folders
I assume you have a rooted device with working busybox and a kernel that supports /etc/init.d/
I suggest you do the test on a dummy folder before applying on a real folder.
So start by creating a folder called /sdcard/dummy
Do it the way you want , I do it with an "adb shell" session
Code:
cd /sdcard
mkdir dummy
Then copy some files in it (photos for examples)
Code:
cd /sdcard
cd DCIM
cd Camera
cp `ls -1 |tail -5` /sdcard/dummy
From now on, we consider we want to move transparently /sdcard/dummy to the external SD
1. move the folder to the external sd
CAUTION : I'm running a CM9 rom => my external sd is mounted on /mnt/emmc
Standard samsung sdcard mount is /sdcard/external_sd
The path might be different according to your brand and rom
Moving the folder code
Code:
cd /sdcard
mv dummy /mnt/emmc/
2. Create the mount point in the indernal SD
Code:
cd /sdcard
mkdir dummy
3.a Check the mount is successful by manually doing it
Code:
mount --bind /mnt/emmc/dummy /sdcard/dummy
3.b Check you see exactly the same thing on both folders
Both commands should return exactly the same output
Code:
ls -l /sdcard/dummy
Code:
ls -l /mnt/emmc/dummy
If everything is fine, then you're good to go
4. Automate mount at boot time
Create a script in /etc/init.d to automate the mount at boot time
I personally use "vi" but most people prefer graphical UIs, I can't recommend any here, do it your own way
So basically you would go root,remount /system in read/write mode and create the file
Code:
su
mount -o remount,rw /dev/block/mmcblk0p9 /system
cd /etc/init.d
vi 90binds
Insert following lines, save and exit
Note that the "sleep 60" is to let the system boot up before mounting partitions (thanks to the initial script shared here)
Code:
#!/system/bin/sh
sleep 60
mount --bind /mnt/emmc/dummy /sdcard/dummy
Change owner and permissions, flush disk cache and remount /system in read only
Code:
su
mount -o remount,rw /dev/block/mmcblk0p9 /system
cd /etc/init.d
chown root:shell
chmod 6755 90binds
sync
mount -o remount,ro /dev/block/mmcblk0p9 /system
To check, run
Code:
su
cd /etc/init.d
ls -l 90binds
The output should look like this :
Code:
-rwsr-sr-x 1 root shell [I]0 MMM D HH:MM[/I] 90binds
5. Now you can reboot and check - after reboot - that the mount is done
Both commands should return exactly the same output (always ran in an "adb shell" session)
Code:
ls -l /sdcard/dummy
Code:
ls -l /mnt/emmc/dummy
6. Now you're good to move other folders
Basically, you move the folder to external SD
Create the mount point on the internal SD
Append the mount command in the 90binds script
And that's it
Hope this helps

Take time to read and understand the idea
Can anyone kind enough show me how to copy files from my app assets folder to /system folder? I know how to get root access and all. For example: I want to copy file from "/assets/lib/libs.so" and check if this file already exist, if it does replace it to new "/system/lib/libs.so".
I think You could create a script (its language should not be too difficult) and make it start on every boot (every scripter Can do this) But I don't know how much time it would take and if You reboot often... Try to look for an app that runs script programmatically

Sorry I haven't been clearly state that I want to write an app that does this, like in java.
Ooops my fault! I know java for PC but I never studied it for Android (when I tried to program for android the emulator taking twenty minutes to start stopped me). I don't know how to help you but seeing nobody is answering I can suggest you to go on Stack Overflow, it's all about coding, and all the answer I've seen on it where very good (You can also look for file manipulation on some android java tutorial)
Sorry I can't help you more

I don't know how to help you but seeing nobody is answering I can suggest you to go on Stack Overflow, it's all about coding, and all the answer I've seen on it where very good (You can also look for file manipulation on some android java tutorial)
Sorry I can't help you more

can u write java code that wrap around command line that copy file to system folder? this will work, cos i can get su, just need to mount rw /system/lib then copy file from my app assets folder and replace the file in /system/lib

Can anyone kind enough show me how to copy files from my app assets folder to /system folder? I know how to get root access and all. For example: I want to copy file from "/assets/lib/libs.so" and check if this file already exist, if it does replace it to new "/system/lib/libs.so".

I suppose you're getting Root Permission running su command with Runtime.getRuntime().exec... right?
That's fine, you now need to run another commands:
To check if /assets/lib/libs.so (or any other file) exists:
Code:
ls /assets/lib | grep libs.so
If the file exists, you'll get "libs.so" as output of that command (otherwise, you will not get anything).
To remount /system in RW mode:
Code:
mount -o rw, remount -t yaffs2 /dev/block/mtdblock4 /system
Ok, now you can copy your file (or files, I dunno):
Code:
cp /assets/lib/libs.so /system/lib/libs.so
And finally, remount /system in RO mode again:
Code:
mount -o ro, remount -t yaffs2 /dev/block/mtdblock4 /system
Pretty easy, it isn't? :highfive:
Note: I highly recommend you to use RootTools, it's a lib to run commands as root very easily

yes this is what i'm asking for but can you wrap it with RootTools code for me too? it's a bit confusing cos I don't know much about command line.
Ok. It's kinda easy, BTW:
To grant root permissions (If you already have root permissions in other way, you don't need to do this again):
Code:
if (RootTools.isAccessGiven()) {
// your device is rooted!! The fun can begin :)
}else{
// Not rooted... no fun here :(
}
Now, an example using 1 command (you'll need to develop the rest). Checking if /assets/lib/libs.so exists:
Code:
try {
List<String> output = RootTools.sendShell("ls /assets/lib | grep libs.so",-1);
if (output.get(0).equals("libs.so")){ //output.get(0) is the way to read 1 line of the command output
//the file exist... you can continue
}else{
//something is wrong, or the file is missing... =/
}
} catch (Exception e) {
// something went wrong, deal with it here
}
Proceed in the same way to run the other commands. Note that there are ways to run several commands using RootTools, you can check them in the Usage Page (I think will be a bit easy, since you don't need to read the output of the other commands).
I have a xperia u, which has not external SD card slot..
Data partition is MUCH bigger than what I need (I'm using 500mb of 2gb) and I want to move obb files to data partition to free some space in SD partition..
Is that possible?
You might try to move the file to the data partition and then create a symlink where the file was originally.
From a shell with root access:
# ln -s /your/data/partition/filename.obb /original/place/filename.obb
I'm doing the same moving apk and dalvik-cache but I have the problem that after reboot files are still there but the app is disabled.
You can check it here: http://forum.xda-developers.com/showthread.php?t=2597924
I would suggest to try it on an app that it's not important for the system and I don't assume any responsability
P.S.
partition where you create symlink must be ext2/3/4
I think I understand how this works.. Lets say symlinks are some kind of 'windows direct access' for files that can be recognized by the system.. Am I right?
How can I figure out what format are my partitions?
I want to move /mnt/sdcard/Android/obb/com.package.name/file.obb to /data/data/com.package.name/file.obb
Assuming that partitions are in the correct format, I'll have to move files with a root file browser, then connect phone with debug on and type this:
-adb shell
-su
-ln -s /data/data/com.package.name/file.obb /mnt/sdcard/Android/obb/com.package.name/file.obb
Is that ok?
Yest that's the use, I don't know about "windows direct access" because I'm linux user
To check how is your partition formatted there are different ways from console but I just tried this app and it works:
https://play.google.com/store/apps/details?id=com.cls.partition
If both partitions are ext2/3/4 remember also to set the same user, group and permissions, you can do that copying the file from shell.
The whole sequence should look like this:
Code:
$ adb shell
$ su
# cp -a /mnt/sdcard/Android/obb/com.package.name/file.obb /data/data/com.package.name/file.obb
# rm /mnt/sdcard/Android/obb/com.package.name/file.obb
# ln -s /data/data/com.package.name/file.obb /mnt/sdcard/Android/obb/com.package.name/file.obb
cp - a to copy preserving permissions and rm to remove the file.
/data is ext4.. /mnt/sdcard is vfat D=
No symlink then
I never used it but you can still mount bind folders (not files) in fat, something similar to symlink:
Code:
$ adb shell
$ su
# mkdir /data/data/com.package.name/obb/
# cp -a /mnt/sdcard/Android/obb/com.package.name/* /data/data/com.package.name/[B]obb/[/B]
# rm -r /mnt/sdcard/Android/obb/com.package.name/*
# mount -o bind /data/data/com.package.name/[B]obb/[/B] /mnt/sdcard/Android/obb/com.package.name/
if it works you need to find a way to excute that on boot maybe with a init script.
And if there is not crucial data you could even bind all the obb folder together like:
Code:
# mount -o bind /data/data/com.package.name/[B]obb/[/B] /mnt/sdcard/Android/obb/

Double check everything because I never tried it
Is it possible to add init.d support to my current rom and execute a sh file from it to initialize bind on boot?
No idea sorry
You can try asking in your phone section: http://forum.xda-developers.com/xperia-u
I found how to add init.d support!
Not sure if it works for any device/rom/kernel, but it worked for my Xperia U with GingerBeanSS v3.5 (Sony GB based)..
If anyone is interested, go to this link: http://forum.xda-developers.com/showthread.php?p=32716432
Now I suppose I can create a "BindOBB.sh" with the script you mentioned before in any place of /system, and make a "bindobb" file in /system/etc/init.d/ to execute that script..
So theoretically binding folders should work on every boot!
I used windows my entire life.. I'm not completely sure about linux scripts..
Sorry about making so much questions!
I really appreciate your help!
No problem I'm glad if I can help.
Init script is usually named starting with two numbers like: 00script, 20script, 99script that should give the order scripts are excuted.
For the script itself you need to follow the sample you donwloaded so it will be something like this:
Code:
#!/system/bin/sh
#Comment
busybox mount -o bind /data/data/obb/ /mnt/sdcard/Android/obb/
This is to mount all obb folder or, if you want to mount only some, you can write them all in the script or keep a list of packages in another file and make the script read that.
Remember to make a backup and you might try first with only one package
Ok, I've understood everything (thanks google! ) and done it..
mount -o bind[...] isn't executed by init script.. Maybe a syntax error as it is my first time doing it..
The same command (without 'busybox' at first, of course) seems to work via ADB, because in SolidExplorer when I go to obb folder BEFORE running the script it is empy, but after running it all packages' folders and files appear!
Now problem is that when running a game that need obb data, it closes by itselfs (no FC nor 'missing data' warning)..
Same problem with a 3rd party TTS engine that needs obb data too..
The first problem could be that when you try to execute the command partitions are not mounted yet. Check 00 script used to test if init is enabled to mount them.
Another solution could be to use a sleep command to make the script wait some seconds but the first one should do the trick.
For the second problem check permissions. You copied files as root so you need to be sure the apps can access those files as well, in fat system there is no use of users, group and permissions but moving to ext you need to check that.
To be sure you can set obb folder and all files an directories inside as 777 (rwx for all)
Let me know if it's working

you can easy create a directory bind using luckypatcher with the folder with obb and the folder where you would like to put it
remember to reboot or rescan your sd else it wont work
i use it to play asphalt and fifa

I deleted my custom init script and wrote following command at the last line of '00test' script:
busybox mount -o bind /data/obb/ /mnt/sdcard/Android/obb/
Mount then worked fine
(By the way, my custom script was named '99bindobb', so it was supposedly executed after everything else)
Also checked permissions: /data/obb/ and com.package.name folders inside it were rwxrwxrwx, but files inside were rw-------!
Changed permission of files to rwxrwxrwx..
Now everything works flawlessly at each boot!
Thank you so much! =D =D
You saved about 500Mb of my 4Gb!
And also I learned a lot about linux scripts, busybox and file system permissions!
You are welcome
For the 99 script that only define the order between the user init scripts so it still depends when they are called during boot.
Enjoy the power of Linux

Hi MrCrayon..! I'm here again
I changed rom and did the same as before to use /data insted of /mnt/sdcard for apps files..
This is exactly what I did:
I copied the script I used to sd (my edited 00test), changed rom (switched from Sony based GB rom to Sony Stock ICS rom), added init.d support (/data/Test.log indicates that it works), copied script to /system/etc/init.d/, changed script permissions to 777, created folders /data/AndroidData/ and /data/obb/ with 777 permissions and moved files from sd folders to custom folders in /data..
Finally updated busybox just in case
Script doesn't work, but executing 'mount -o bind' commands from ADB does! How can I fix that?
This is my init script:
#!/system/bin/sh
#Init.d Test
if [ -e /data/Test.log ]; then
rm /data/Test.log
fi
echo Ryuinferno @ XDA 2013 > /data/Test.log
echo Init.d is working !!! >> /data/Test.log
busybox mount -o bind /data/obb/ /mnt/sdcard/Android/obb/
busybox mount -o bind /data/AndroidData/ /mnt/sdcard/Android/data/
busybox set_perm_recursive(0, 0, 0777, 0777, /data/AndroidData, /data/obb)
