_________________________
I was over at nexusonehacks.net and looking at the ubuntu on nexus one hack and was thinking that this could be ported to the nook color. The idea is to run ubuntu from an img on the sd card.
The following is a modified version of the "how to" orginally posted here
http://nexusonehacks.net/nexus-one-hacks/how-to-install-ubuntu-on-your-nexus-oneandroid/
Credits
The guys at NexusOneHacks
xda user munday who has modified the scripts to work for the nook color
Devs at XDA Developer for the Ubuntu ARM image for HTC HD2
Saurik (Jay Freeman) for the Debian G1 script, which was hacked for Ubuntu on Nexus One! and then re-hacked for the Nook Color by munday
Here we go:
1) Go download the ubuntu file here: http://www.megaupload.com/?d=67BU4Y3T
2) Extract the contents using 7zip http://www.7-zip.org/download.html
3) Copy the extracted folder "ubuntu" to the root of your SD card
4) Unmount the nook from your pc, go into the app NookColor Tools (if you don't have it download it here courtesy of Ben 74 and click All Settings->Development then uncheck Auto Mount. This will prevent the SD card from being mounted automatically when plugged into the PC
5) Plug the Nook back into your pc and open a command line then navigate to your android sdk folder ie C:\android-sdk or wherever you have it and type
Code:
adb devices
Hit enter and make sure that the nook color comes up (should be the SN of your Nook)
Note: This can also be done from terminal emulator instead of adb...but it is kind of a pain
6) Now we want to go into the command line on the nook so type
Code:
adb shell
Hit enter and this should bring up a "#" sign.
7) Type
Code:
su
hit enter (I do this just as a force of habit)
8) Now we navigate to the ubuntu folder we just copied to our sd card by entering
Code:
cd /sdcard/ubuntu
hit enter. To confirm you are where you want to be you can type
Code:
ls
and it should list the contents of the ubuntu folder.
9) Run the setup script ubuntu.sh by entering the following:
Code:
sh ./ubuntu.sh
hit enter
10) Now type
Code:
bootubuntu
and hit enter
11) So now we have ubuntu command line up and running which should look like:
Code:
[email protected]:/#
We will need to get some packages to run a gui and then connect to it via VNC client. So we need to update a few things first. Type:
Code:
apt-get update
then
Code:
apt-get install tightvncserver
now we need the gui elements so enter this:
Code:
apt-get install lxde
12) Type the following:
Code:
export USER=root
vncserver -geometry 1024×600
this sets the resolution...you can change it to play around, but the native resolution for the nook is 1024x600. This is also where you will set the password for your vnc server...make sure to remember it
13) Next, we are going to add the following to /root/.vnc/xstartup file using cat command: (hit enter after each line and ignore the fact that it looks like it does it twice)
Code:
cat > /root/.vnc/xstartup
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
icewm &
lxsession
After hitting enter after the last line press "Ctrl+D" twice then press enter
14) We need the vnc server to start every time we start ubuntu, type this:
Code:
cat > front
export USER=root
cd /
rm -r -f tmp
mkdir tmp
cd /
vncserver -geometry 1024×600
Same as before, hit enter after each line then after hitting enter for the last line press "Ctrl+D" twice then press enter.
15) Enter this
Code:
cat front /root/.bashrc > temp
Then
Code:
cp temp /root/.bashrc
16) Now on the nook open up your vnc viewer app (android vnc viewer or PocketCloud...or whatever you use)
Use the following settings:
Host Address: 127.0.0.1 (some don't require this)
Password: the password you set up in step 16
Port: 5901
Save and then click connect and you should be up and running on ubuntu! To leave ubuntu type exit from adb. This should kill ubuntu. Exit adb and then you can disconnect the nook from your pc.
To start ubuntu from the nook open up a terminal emulater and type:
Code:
bootubuntu
Hit enter, this should bring up the [email protected], hhen press "Home" key and open up your vnc app. Now you are ready to rock your Linux tablet!
You could also use gscript lite to automate the process of starting ubuntu so you don't have to type it in the terminal everytime. You can get gscript lite from the market or download the file I have attached.
It does seem a little laggy..just a little...for now anyway
To exit ubuntu: Disconnect the vnc client then hold the "Home" key (I use button savior which brings up a nice little task manager) and click the Terminal emulator when it pops up under running tasks. Once you are back in the terminal you can type:
Code:
exit
to shut down ubuntu.
Enjoy and make sure you thank munday and the guys at nexusonehacks and all the devs who helped make it possible.

EDIT:
I noticed that after rebooting the nook would hang at the "Future of reading" screen....if this happens turn the device off remove the sd card the turn the nook back on. It should boot fine. After it's finished you can return the sd card and mount it. This is strange and I'm looking into it. I'm not sure if this is limited to me or if it is universal to all nooks. It also still fails at shutting ubuntu down for some reason. I'm still looking into this.g into this.
I got it going, just needed a few "busybox"-es here and there . It needs some work, right now to get X you have to use VNC.
It's sluggish but a bit more work might just yield something a bit more usable. I'll play more tomorrow night.
Here's my scripts:
ubuntu.sh
Code:
mount -o remount,rw /dev/block/mmcblk0p5 /system
busybox modprobe ext2
rm -f /data/local/bin/fsrw
rm -f /data/local/bin/bootubuntu
rm -f /data/local/bin/unionfs
rm -f /data/local/bin/installer.sh

mkdir /data/local/mnt
#busybox clear
rm /system/bin/fsrw
rm /system/bin/bootubuntu

busybox cp -f fsrw /system/bin
busybox cp -f bootubuntu /system/bin
busybox cp -f unionfs /system/bin
busybox cp -f mountonly /system/bin
cd /sdcard/ubuntu
busybox chmod 4777 *

busybox chmod 4777 *
cd /
#busybox clear

bootubuntu
Code:

export bin=/system/bin
export mnt=/data/local/mnt
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH

umount $mnt/dev/pts

umount $mnt/sys
umount $mnt
Then just followed the instructions at nexusonehacks.
note: to run bootubuntu i had to use sh and the use the full path:
Code:
# sh /system/bin/bootubuntu
other note: I was using adb not a term app on the nook.
Obligatory video
I can't post links yet so check: youtube.com/watch?v=TnXfZ6aagn8 for a really boring video
EDIT: switched the names, DOH!
I also had to use sh and the full path also. Thanks for the update on the script...gonna try it in the morning (it's 2am here) will also see if I can help to get it running smoother. What class SD card are you using? I imagine a class 4 or higher would yeild better results as far as responsiveness goes.
The sd is a class 2 that came in one of my dev phones. I'll pick up a faster one tomorrow after work and test it out.
It's just about 3am here now, we must be in the same time zone.
I'm going to bed now, but first here's a modded version of the script you had originally posted that also works now.
bootubuntu
Code:
#!/bin/sh

umount $mnt
busybox losetup -d /dev/loop1
#unregistering the loopback device just seems to die. need to fix or remove.
I'll look at the N1 formus tomorrow too and see if they have made progress in getting X to run fast or without need for VNC.
Nice work, I am addicted in seeing the crazy crap people are doing everyday.
Couldn't sleep so I'm messing around with it now...I'm using a class 4 and have it up and running. It does seem to be a little laggy, but I don't have a class 2 to compare it to. Let me know what you find out, I'll keep playing with it also to see if I can get it to be more responsive...but we are definately on our way to having a great little linux tablet in addition to android. You should also be able to use this for other builds of linux also by just changing out the .img file to a flavor of your choosing. I'm excited
I have also updated the OP with the how to and credits. Really appreciate your help munday.

Edit:
Running into some strange occurrences...it appears that when you type exit from the terminal to kill ubuntu, I believe ubuntu stays running...anyway, I'm going to bed and will work on it more tomorrow.

Are there any increased risks with changing the version you use?
Well, you will want to make sure that the build supports ARM based devices.

Is there a problem with how I copied the script? I assume the first part about the file existing is due to this being the third or fourth time I've tried running the script (Unsuccessfully), but I've no idea how to interpret the rest.
Thanks

Try using these, just unrar and then copy them in your ubuntu folder, if it asks to overwrite just click yes...also you have autmounting of the sd card turnned off in nook color tools settings right?
Yeah, it must have been an error on my end. Using the updated scripts you posted worked like a charm.
Thanks!

Good to hear!
I'm currently working on making this a port to the SD card so that with the sd card in it boots into ubuntu from power off, and with the sd card out it boots to android then you replace the sd and use it for storage like normal. It will also run a lot snappier....well that's the idea anyway.

Booting from SD in the same fashion as Nookie Froyo? That sounds like it would give a huge performance boost over the current method, I can't wait to see what you come up with.
This should be acheivable using the method mentioned in this topic:

I was thinking the exact same thing, the nook seems to like booting from sd, so we should be able to set up the partitions like the foryo sd and edit the init.rc and env.txt to boot ubuntu instead of android. Just a theory though. It's my plan for tonight anyway.

I also stumbled across this: http://androix.org/ Which talks about a native android xserver which does a way with the vnc aspect altogether. I downloaded and attempted to install but I get the error "There is a problem parsing the package" and I haven't had any luck plus there isn't much documentation.
Let me know how it goes munday, I'll be working on the same thing later (have to take the fiance out for dinner)
question
I was just curious, after installing ubuntu can we install flash as we would had we booted linux from netbook?
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,
Thks for your shares. I have a question. How run init_expandsd.sh?
I tried gscript and init.d, but doesn't seem to be working
woohoo a great dev has come. glad you got here mate! love your work on Desire section.

you can try to use terminal emu, just type su then navigate to folder where the script located, then type sh init_expandsd.sh then enter. this might do the trick to execute .sh

It's a great idea thanks a lot for your work. I was wondering why ln was not working.
But too bad it does not work for me, i get the following error :

Thanks again
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

Just posted
Take time to read and understand the idea
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.

Yes. I took to pictures and then tried running it and it still fails. I wonder if its not working cause I'm on CM10?

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.

Where save the file ?
Hello
I'm french and don't speak english very well ....
I try to do what is explain in this topic ( for tethering with a Sony Ericsson KYNO V - ics 4.0.4 with root access ....
I don't understand where to save the file with sh extension
What i want to run is : #!/system/bin/sh
iptables -P FORWARD ACCEPT
iptables -t nat -A POSTROUTING -o rmnet0 -j MASQUERADE
My script is :
su root
sh scripttether.sh
Thank you very much for your help

Open a new file, and write:

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.

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/
You can also check this thread:
http://forum.xda-developers.com/showthread.php?t=1410262
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)
I have found myself repeatedly moving the downloads and photos folders to my external SD card, so I decided to try and make a small script or binary that can automate this task without consuming much space. I tried a plethora of "compilers" that run in android, and only Termux with clang could create a file transfer binary, but it can only write to one folder in the external storage, in its app data.
So, I'm asking, is there any way to automate moving folders into the external storage that won't require a large app?
@psychoreactor
Take note that you can't move directories/files if FS of source location and target location is different: hence you have to use copy instead
A small shell script like this example
Code:
#!/system/bin/sh
cp -ar /sdcard/Photos /ext-sdcard/Photos /
rm -rf /sdcard/Photos
mkdir -p /sdcard/Photos
cp -ar /sdcard/Downloads /ext-sdcard/Downloads/
rm -rf /sdcard/Downloads
mkdir -p /sdcard/Downloads
does the job
You run such a script at pre-set time by means of Android's crond service, preferredly when Android boots + 20 seconds
IMHO a far better method ( what doesn't impact internal SD-card's lifespan ) is to format the external SD-card as EXT4 ( this is particularly important, as the file system used on the external SD-card is usually FAT or FAT32 ), create there folders Photos & Downloads, delete original folders, then symlink original folders to these new folders: This way all photos & downloads automatically land on external SD-card.
Code:
ln -s /ext-sdcard/Photos /sdcard/Photos
ln -s /ext-sdcard/Downloads /sdcard/Downloads
