Few EXt2 questions - G1 Android Development

Is it possible to veiw the files in the EXt2 partition from our G1 terminal? If so, can we also delete files? If so, someone explain how, thanks.

asuming is mounted on /system/sd
just
cd /system/sd
ls -la /system/sd
to list the files

is their a way to erase those files

There are commands for deleting files on Android. Look up the Linux Command prompt commands for performing those functions.

If you've rooted your phone and don't know the commands already, you haven't been paying attention to the instructions.
ls = directory listing
cp = copy
mv = move/rename
rm = remove
Those are the very basics. Remember that Unix-like operating systems are case-sensitive and file.txt is different from File.txt or file.TXT.
If you're using wildcards to delete everything, take a precaution and use the dot-slash. It could save you a lot of trouble by ensuring you're only deleting files in the current working directory. To remove all text files in a directory, for example, you'd type rm ./*.txt

god, i hate how rude people are. I grew up with DOS, so dir, and del come more naturally to me than linux commands. So just ease up on the ppl that don't know linux. I didn't know linux til i started to IRC and wanted to run an eggdrop bot. Not like everyone has irc'd or compiled, or whatever. Heck, it has been so long now, I could not write an irc script or egg addon, and I think i was the first to develop some scripts in IRC 20 years ago. So all I can say is chill.
Shaggy

??huh??
whats the beef all about?
you can google the command and linux and probably have a ton of sites that list and explain the usage and stuff like that for *nix commands unix is a very old OS linus torvalds just woke up 1 day at age 15 or sumthin and said im gonna make a unix kernal that runs on my intel based pc and then instead of selling it and making a fortune I'll give it away and still make a fortune.
LINUS is the greatest man of our time, when the other OS was charging BIG $ to run Apache web servers in the .com boom (even more so now) linux was FREE and gave better throughput on the same hardware
Now if you want a pretty box booklet and packaging as you have become accustomed they have them to, some just feel better if they pay for it, free must not be as good as the one that costs right?
why did I bother just rambling, please ignore the babbling lunatic in the corner he is harmless

if you dontknow how to be polite to the noobz then dont say anything at all. let someone else answer their questions.

Hi Beartard,
Thanks for the info.
This site has such a wealth of information, that it can be overwhelming to many members.
Can you tell me how to copy my apps-private from my ext2 partition to my sd card partition so I can back them up?
Thanks

uh you wan't to copy your "app-private" folder as a backup in to yoru sdcard correct? well try this
busybox cp -a /system/sd/app-private /sdcard/app-private
if it don't allows you to copy do this command to re mount the system as read-write
mount -oremount,rw /dev/block/mtdblock3 /system

Hi Nitro .
I tried it both ways and it says operation not permitted.
-------------------
Update:
But wait, I connected my phone to the computer and the app-private is copied to the sdcard.
Your procedure worked!
I erased the folder that was copied to test it again.
Then I used just this set of commands and it worked again:
busybox cp -a /system/sd/app-private /sdcard/app-private
So you still get the same error, but it works.
Thanks alot Nitro!!!

u tried it as root? what error u got?
well glad it worked.

Hi,
The error says:
"cannot preserve ownership of ... cannot preserve permissions of ... operation not permitted"
for every file it tries to transfer.
But then when you look in your sdcard the app-private is there.
So it is a false error.
Thanks again.

Hi,
Use terminal emulator jf 1.41 or better
type su enter
then the busybox commands
Connect your phone to your computer and look on your memory card.

hey guys need some help here i have the same problem, (as far as the error saying 'no such file or dir') and i tried your suggestion about typing su first then the busybox commands.
i have the most current terminal emulator, unfortunately i still continue to get the same error every time i try to run the busybox commands. it just simply say 'no such file or directory"
you guys have any suggestions for me to try ?
any help would be great.

the error i get is "cannot preserve permissions of" i think that error is not something harmful im n o *nix expert but is just saying it wont save the permision of that folder i think...
Code:
# mkdir /sdcard/bk
mkdir /sdcard/bk
# busybox cp -rf /data/app-private/ /sdcard/bk
busybox cp -rf /data/app-private/ /sdcard/bk
cp: cannot preserve permissions of '/sdcard/bk/app-private': Operation not permi
tted
# ls /sdcard/bk
ls /sdcard/bk
app-private
thats what i did.. worked for me.. moved the app-private in to a folder named bk inside the sdcard

Hi,
We are assuming that you have already moved your apps and caches to the memory in a ext2 partition, correct?
Otherwise this will not work.
I 1st followed all the instructions in this post:
http://forum.xda-developers.com/showthread.php?t=468959
All this has to be done 1st including the 2 step 13's

nitro all i can say is thank you very much, i was looking through a 15 yr old unix book looking up commands, and it's just been so damn long ago i couldn't put it together.
thanks a ton. i'm sure you saved me at least a few hours.
@bestwebs ya i have done everything else including moving things to the ext2 partition i was just stuck on a few comands here and there.
but again thanks to both of you, and i'm all setup up now.

Hi,
Nitro is a real blast!
Glad it's working.

can u write to system folder?

Sorry if this has been answerd, tried searching but didnt find it. (I am driving and looking at same time...ya i know)
Im trying something and i need to put a file in the system folder on the phone. I tried cut/copy and past from my sd card to it and says failed in linda file mgr. I tried in terminal and it gave me cross device link error, if i even put commands in correctly. Linux is new to me, lol.
I am on 1.5 h build for referance
Thanks in advance
You might have to do it in ADB.
adb remount
adb shell
[your command]
besides that, you cannot mv across file systems either. mv is essentially a renaming tool, if you want to move something use cp and rm.

I presume you have little *nix background... 'mv' essentially performs both cp and rm functions in one fell swoop. I use it on my desktop and laptop daily. It will copy before it deletes as well, so if you are interrupted, the source files wont be gone with a corrupt destination.
Get Terminal Emulator
this is easily accomplished via terminal emulator, if u have a recent haykur0 build it should include busybox what u would do in the termial type
Code:

busybox cp /sdcard/namofyour.file /system/nameofyour.file
thanks guys. got same error when used shell. got it done using:

Ash as login shell

Hi All,
The Ash shell provides a few advantages over the Android default sh shell such as command history and cursor handling at the prompt. There are other benefits, but these are the first that come in most handy (to me).
The following tutorial will get you ash as the login shell with as yet no ill effects:
Note: that in my case, I'm using my android2sd construct and thus this modification is being done to my active overlay profile setup, thus to undo it I can simply boot into "safe\\normal" mode and undo the changes without possibly locking me out of the console should it have failed (which it didn't) But you can edit the Android /system/bin/sh file in this manner directly.
Ash as Login Shell:
OK, make the /system fs read-write:
mount -o remount,rw /system
Click to expand...
Click to collapse
Note: that the fs type is not needed, and in my case is not yaffs but ext3, Android will figure it out proper.
Next,
cp -a /system/bin/sh /system/bin/sh0
Click to expand...
Click to collapse
(this is for backup purposes and allows us to undo the change if so desired, or delete it if no longer needed).
Note: I'm using JF1.51 roms, so busybox ash is available as /system/xbin/bb/ash, so that is what I am using here; use ash however you are able to access it.
echo "#!/system/xbin/bb/ash">/system/bin/sh
echo "/system/xbin/bb/ash \[email protected]">>/system/bin/sh
Click to expand...
Click to collapse
Please note the use of (redirect\\overwrite)> and (redirect\\append)>>.
This will overwrite sh with a script to load the desired shell, executing any command-line arguments passed, and preserve the permissions of the original sh file. You can manually set the permissions the same as they are for our sh0 backup if the permissions (root.shell)(0755) don't seem to keep.
Finally reset the read-only state of /system:
mount -o remount,ro /system
Click to expand...
Click to collapse
Now if you shell-in\\telnet-in you should get the ash prompt which unlike the Android sh default prompt, includes the present working directory(pwd) ie: '/#' instead of just '#'.
Note: A reboot should not cause the loss of the modification, but if does, copy the new sh script to your /data/local/bin location or something and copy it back via boot script or something.
Shell Scripts:
If you're like me, you discovered that Android didn't need the interpreter declaration comment in scripts, and thus may not have used them...Well, you will need to update your scripts to include them by adding something similar to the following as the first line of your scripts:
#!/system/xbin/bb/ash
Click to expand...
Click to collapse
Again, please note that I am using JF1.51 roms and the location of the busybox ash shell is what I'm listing; put the full location to the shell you intend to use as this location.
Without the interpreter declaration, ash simply complains 'not found' at the first command, as ash doesn't know how to interpret the script, and doesn't seem to default to the login shell.
Hope someone finds this helpful!
sweet. This is going to be very useful
BAM. thats sexy. i just did this on CM3.6.7.1. works like a charm.

im not sure about the other features, but the one i installed it for is to have your working directory in front of ur prompt. ex:
Code:
/# cd /sdcard
/sdcard # cd /system/sd
/system/sd #
etc...
EDIT: Also, if you use ConnectBot, you'll notice with the regular sh, if u scroll up with tracball, you get BS characters on the prompt. with THIS one, when you scroll up, you get last command entered. VERY handy for when you mistype one character on a long-ass command.
I love you
Couldn't you do this?
Code:
mv /system/bin/sh /system/bin/sh0
ln -s /system/xbin/bb/ash /system/bin/sh
great job, i'm going to get ash working on my G1 (CM-3.6.7.1)
Thanks.

Yes, I reckon you could. Though I had done a few experiments where the symlink failed, but I'm fairly sure it was do to the link: /system/xbin/bb/ash -->../busybox and /system/bin/../busybox not existing...so I did it via script. Many ways to skin a cat they say.
Thank you all... this is fricken awesome!!

It gives a more advanced shell for when you use the command line interface or telnet into your G1. If you don't use the command line a lot, it won't help you.
As for specific benefits to the advanced version, it was listed in the first post.
Hi,
imho this is rather a hack that exposes you to the risk at least on CM to loose your
shell during boot as xbin.sqf the compressed squashfs filesystem containing
busybox is mounted rather late in the boot process. A cleaner solution would be to
move busybox to system/bin and link it to sh. That way you ensure that sh will
always be accessible during boot and also later on, thus not interfering with
further developments. A alternative could be to compile a standalone version
of busybox containing only ash (for size reasons, as size in /system/bin is precious)
copy that to /system/bin and link sh to it.
Seems to work fine on Dude's. Not really sure how it should open, but I type "ash" at the prompt and I get the /$ and /# if superuser. I also get the command history by rolling the trackball, which is a very nice feature.

Safest method will be to change to ash shell once terminal app is started (same as typing "ash" to switch shell from sh to ash). I don't know how to do it in android (in linux you could add it to your login script).
So if someone knows how to execute a command when we login using the terminal app, then switching to ash shell would work without fear of breaking any other functionality.

[DEV] Apps2SD and Darchstar-2.1 ROM

The focus of this thread is to sort out the Apps2SD issue in cyanogenmod-darch 2.1 ROM (like the title says). Please do not post here unless it relates to this issue.
That being said, here is where I was at in the original darchstar 2.1 thread:
watzone69 said:
Taken from the instructions darchstar gave in the first post of his thread...
Code:
adb remount
adb push e2fsck /system/bin
adb shell
cd /system/bin
chmod a+x e2fsck
a2sd
reboot
First, the "chmod a+x e2fsck" command doesn't work for me (EDIT: I discovered that it WILL work in recovery mode). I had to use "chmod 777 e2fsck". After entering "a2sd" it gets enabled. After rebooting, apps2SD is NOT enabled anymore. I realized this by doing this test:
Code:
adb shell
cd /data/app
pwd
If your apps2sd is enabled, you will get "/system/sd/app" returned to you.
If you get "/data/app" returned instead then apps2sd is NOT enabled!

Gbhil then replied...
gbhil said:
After you restart, can you re-enable a2sd by running a2sd from a terminal as root?
If so, do all your apps still appear and are they usable?
If the above is true, try adding this to the end of gumbo.sh
Code:
su -C a2sd
for a quick fix.
Start a thread (to keep things less cluttered) about it and I'll help you guys dig into the boot image and see why it's not sticking.
Click to expand...
Click to collapse
So, I rebooted and tried to run "a2sd" from the android terminal but it spits out a long string of errors:
Code:

+++ Apps-to-SD successfully enabled
So, there is no "app" or "app-private" in the "system/sd". Is a2sd supposed to generate those directories or are they supposed to be there before hand?
Anyway, the result is that I lose all of my shortcuts to the apps and market shows them as not installed even though they are.
BTW, I am not a dev or even that great at code or linux but I can usually pick stuff up fairly quickly. Just want to help fix this!
EDIT: The only thing I have found to work is to flash this kernel:
http://forum.xda-developers.com/showpost.php?p=5712377&postcount=1406
However, some people get stuck in a boot loop after flashing this.
Running into the same issues as Watzone so I can confirm that he is doing it correctly. =P
Here are all of the related commands that have been suggested whenever the question of apps2sd has come up in the darchstar 2.1 thread.
Code:
adb remount
adb shell
mkdir /system/sd
Code:
adb remount
adb shell
busybox --install /system/xbin
a2sd
Code:
cd C:\android-sdk-windows\tools
adb remount
adb shell
chown system.system /data/app
chmod 0771 /data/app
For the next command, boot into recovery and do the following:
Code:
adb shell
mount /system
exit
adb push e2fsck /system/bin
adb shell
cd /system/bin
chmod 777 e2fsck
Now, boot normally and go back to your CMD prompt...
Code:
adb remount
adb shell
a2sd
EDIT: In other threads I have seen the command...
Code:
apps2sd on
...used to enable apps2sd.
Doing all of these WILL allow the final "a2sd" command to enable (testing with the "pwd" command) but it all goes KAPUT after a reboot.
why it's not being enabled at boot time is because the init.rc isn't calling /system/etc/init.d/04apps2sd . I'll be sure that we fix that in my next release
And there you go.
It works here, but now I know why. I'm still using an old version of the boot image that looks for /system/bin/a2sd to load it, and an older version of the ROM. No sense in me to keep flashing fixes until I'm done tweaking the kernel. When darch says the kernel is good, then I'll catch up lol.
We might as well use this thread to learn to play with the boot image though, that is if you guys want to.
Awesome can't wait for the next release then! Lotsa apps out there calling out to me! Thanks guys =)

You bet. It's about time I got my hands dirty.
I'm game let me know if you need me to test anything!
Cool deal. You need Linux to extract and compress the boot.img, and you need to be current with Perl and running jre5 or higher.
Ubuntu 9.04+ is set up out of the box, but any version can be made to work.
Then grab these files from Lox -

http://forum.xda-developers.com/attachment.php?attachmentid=234040&d=1254622769
and extract them into your sdk/tools dir. (or any dir in your path)
get all that, then pick a boot.img from a rom and put it in a work folder.
Holler when you get that far, or if you have any q's.
I wanna learn myself. This should apply to mac os as well?

np. I'm @work so going slow is better anyway lol.
ok i just ran the files in terminal. so i guess it might work.
I'm back
Inisde the work folder you dropped the boot.img into, run this from a term:
extract-kernel.pl boot.img
extract-ramdisk.pl boot.img
it will give you several files and a new directory. That dir is the unpacked ramdisk. The init.rc file is the one we're looking for. Open it with a Unicode editor and read it. It has it's own syntax, but it's almost like bash and not too hard to figure out. Hopefully you loaded a bootimg that has a2sd in it. Look near the bottom of the file for the a2sd start up line. It will have a2sd, apps2sd, a2sd004 or something like that. Once you find it so you can see the name used, search the rest of the file for that name.
Those lines will show you how a service gets declared and called at boot time.
I'm up and running now. I downloaded python 2.6.4. Do I need to install it or just extract it somewhere? Please forgive my linux noobness.
The other 2 zip files are extracted and in my tools folder. I'm getting the boot.img now.
idk if this will work as i too am a newb to android and the way they deal with the boot process is somewhat a bit different from what i'm used to, but heres a new boot.img if you guys want to flash it to see if apps2sd works. note, this is not a zip, remove that suffix.
to flash it to your phone just move the boot image to your sdcard then reboot into recovery. from there go into adb and mount your sdcard, then flash the new boot image.
Code:
adb shell
mount /sdcard
flash_image boot /sdcard/newBoot2.img
reboot
tell me if it fixes your apps2sd problem or not.

[TUTORIAL] Install applications into SD Card for Samsung Galaxy 5 (i5500)

DISCLAIMER: DO THIS AT YOUR OWN RISK. I AM NOT RESPONSIBLE IF YOU BRICK / RUIN YOUR PHONE IN ANY WAY.
Hi Everyone,
I have some good news for the owners of Samsung Galaxy 5 (i5500) Smartphones.
Doing some research on Google and reading about efforts from other people who could install applications on SD card on other android phones, I was able to develop a method to install application into SD card for the Galaxy 5. Better yet, you won't even need a custom Rom.
Before I get into the specifcs let me state that the following steps are manual and no application is provided to automate the process, so advanced computer skill is required and some knowledge of unix/linux is a plus.
Here we go: PLEASE READ THE WHOLE THING BEFORE YOU START. I MAY HAVE OMMITED SOME COMMANDS OUT OF LACK OF ATTENTION.
1) You'll need to root your phone. There is a lot of guides about this available, just google for it. I've used the SuperOneClick Root to do this.
2) Partition your sd card like this: 1 - FAT, 2 - Linux ext2. Again, there is a lot of guides about this on the net, just google again. I've used Paragon Partition Manager 2010 to lower the size of my FAT partition, leaving a 550MB unallocated space at the end of the card. Then I formatted this space as ext2 in linux, using ubuntu live CD. Most guides around there recommends that you keep this partition between 500~750MB, so I didn’t try with greater sizes. Also, i kept my partition 1 as FAT 16, but FAT 32 might actually work too, try that if you want and post me a reply.
3) Download Titanium Backup (or another app backup tool) from market and backup your applications. You may need to restore your applications to correct some permission problems that may occur after completing this guide.
4) Install busybox. BusyBox is a software application that provides many standard Unix tools, which are not available on stock android. You can get a copy of busybox by clicking on “problems?” button on Titanium Backup main window. It will get installed on /data/data/com.keramidas.TitaniumBackup/files.
5) If you still don’t have Android SDK installed on your PC, download and install it from Google. You’ll need ADB (Android Debug Bridge), which is included in the SDK, to proceed. Now open a shell connection with your device by typing:
Code:
adb shell
Just keep in mind that you MUST be logged as root. Root command prompt is recognized by the # character. If you don’t have root type the ‘su’ command. If even with ‘su’ you couldn’t get root, please review step 1.
6) Create ‘sd’ folder int /system:
Code:
cd /system
mkdir sd
7) Mount ext2 partition into /system/sd
Code:
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
8) Create a folder to store the applications into ext2 partition:
Code:
cd /system/sd
mkdir app
9) Copy busybox to /system/bin
Code:
cat /data/data/com.keramidas.TitaniumBackup/files/busybox > /system/bin/busybox
chmod 755 /system/bin/busybox
10) Copy your applications to ext2 partition:
Code:
busybox cp /data/app/* /system/sd/app/
11) Change permissions of copied applications:
Code:
cd /system/sd/app
chown system.system *
chmod 644 *
12) Now comes the tricky part: making Android mount your new partition at boot time. All the hard work would be useless if Android discarded the mount points every time we restarted our phones. To do this we’ll need to create 2 scripts and store then into /system/etc. Obviously the scripts should be started by init.rc and need to run as root. Fortunately Android’s init.rc have a gap that makes this possible. The scripts are named install-recovery.sh and init-sd2.sh.
install-recovery.sh content:
Code:
#!/system/bin/sh
/system/etc/init-sd2.sh&
init-sd2.sh content:
Code:
#!/system/bin/sh
MYLOG=/data/install-recovery.log
echo "$(date) Starting install-recovery.sh" > $MYLOG
echo "$(date) Waiting SD to become ready..." >> $MYLOG
sleep 10
mount -t ext2 /dev/block/mmcblk0p2 /system/sd 1>>$MYLOG 2>>$MYLOG
mount -o bind /system/sd/app /data/app 1>>$MYLOG 2>>$MYLOG
mount >> $MYLOG
echo "$(date) Finishing install-recovery.sh" >> $MYLOG
If you plan to edit this files on windows I recommend a tool that is capable of keeping UNIX file format, just like notepad++ free tool.
13) After placing the scripts, change their permissions:
Code:
cd /system/etc
chmod 555 install-recovery.sh
chmod 555 init-sd2.sh
14) Rename the default application folder. If everything works fine you can remove this later to save space:
Code:
cd /data
mv app app_old
mkdir app
chown system.system app
chmod 755 app
15) Restart your phone and cross your fingers
16) If you have problems with your widgets don’t worry. You just need to remove then from your homescreen and add again.
17) Check if your applications are running as they should. Restore backups you’ve made with Titanium Backup for the applications showing problems.
18) If your partition didn’t mount at boot, check log file at /data/install-recovery.log
19) From now on your new applications will be installed on your SD Card. You can modify the scripts to store other folders from /data into the ext2 partition as needed. I’ve been running my applications from SD Card for a week now without any problems or bugs.
20) If you can’t make it work, post your question here and I will try to help you out.
21) Donations are welcomed, just drop some money into my paypal account. Just kidding
Good luck and cya!
can this script use for moving /data/data to EXT2?
if can, from where i should start type the script?
i'm still newbie on this
so i'm alittle bit confused, i hope you can help me and sorry for my bad english
i'm already succes from step 1 to step 11
but i'm little confused at step 12
can you explain how to make the script?
should i make those 2 script via notepad++ and then copy it to /system/sd and then continue to step 13?
or should i just type everything on step 12 after step 11 in cmd prompt?
the problem is, if i make the script from notepad++ the android system will just discard my mount point when i restart my phone
and if i just type everything on the step 12 in comand prompt, when i'm type chmod 555 install-recovery.sh and chmod 555 init-sd2.sh like in the step 13, it always say that install-recovery.sh and init-sd2.sh file is not found?
so what should i do?
i'm stuck on step 12
step 12, type it on notepad++ and then you have to change the extension of the file with .sh, after that copied the 2 files to /system/etc

i've already done that
but when i make the script via notepad ++, i'm already make the save type become .sh, so isn't it just the same?
but when i reboot the phone it's still not working
But how to copy this two script files to system/etc??? it's saying permision denied..

I'm use root explorer to move it to system/etc
The script can be moved but it still doesn't work at all :-(

And i can't move them even with root explorer.. i don't get what i'm doing wrong (
@agus
about the scripts, u can check with root explorer, try to view the script and make sure it was the exact same from the script above, coz i experience the same problem for the first time i try this. if u sure that the script are same then try to execute it using root explorer and then go to titanium backup and see if there is there is another storage (usually there is internal and SD card only).
@stasic
use the root explorer to copy the script to /system/etc, don't forget to change the root explorer option from R/O to R/W, this option should be on top of the page, just touch it to change from R/O to R/W.

you was right, after i check the script via root explorer, the script was not the same, after i fix it, everything works like a charm
in a step 2... how to change linux ext2???
any software can change from FAT to ext2???
I've changed root explorer option to R/W and still no luck..
@agus
sama2 bro AKA ur welcome bro, have fun with the app2sd hehehe
@nima
search on google, how to format EXT2, if i correct u can use paragon partition for windows user, but if u use macintosh u can just go to disk utility and make partition with EXT2 format
@stasic
go to the /system/etc and see if it already R/W or still R/O
It's written that R/W but when I copy and paste still nothing happens..
thx guy.... i must try it

In your PC command prompt execute:
Code:
adb shell
Make sure you are loged in as root and in ADB SHELL try this:
Code:
mount -o rw,remount /dev/stl12 /system
Then execute:
Code:
mount
If your mount result has a line like the one bellow, with the rw set, you'll be able to copy the files.
Code:
/dev/stl12 /system rfs rw,vfat,llw,check=no,gid/uid/rwx,iocharset=utf8 0 0

Try the same thing I posted above. I don't have Root Explorer installed here, so you should be able to finish this guide without it.
stuck in step 2
cant mkdir....
Hi, nice guide!
I succeded with this the first time I tried but now I have changed to a larger sd card and I can't get it to work.
The log file says that it failed to mount the mmcblk0p2 folder, and now when I check it doesn't even exist. What should I do?
Hope I can get help.. thankful for response. /Mattefacit

"No such file or directory" if tried run binary file in TWRP

I need to run a binary file, dalvikvm which located in /system/bin from TWRP terminal, but no matter what, it says, "No such file or directory found", and then I found that this is link file located another directory, I cd'd there and tried, but still the same result
I can be able to run the same file in Termux without any issues
Can anybody please help me on this?
Thanks
Hi, I think you need to mount the system partition before being able to access it. It's not mounted by default on TWRP, but when the phone is on it is (otherwise Android wouldn't work)
If you need help on how to mount partitions on TWRP, ring me (or google it, it's actually pretty simple)

Thanks for replying, it wasn't mounted at first, so I had mounted, still it didn't work, while some of the files in bin do work, some don't.
Then I copied the file to /sdcard and /tmp, and tried execute from these folders, still
Well, if when you're free, can you confirm if it's running on yours?
File: /system/bin/dalvikvm
Thanks once again

I didn't found it inside, but it may be because I'm not rooted.
While searching around I've found this :

I looked into it.
I had no opt folder in root directory. So I made one, and moved dalvikvm to there and tried execute this time, it said permission denied, so I gave it chmod 755. But after that, it says "there no such file or directory".
Well, do you telegram account, so I could contact you there.
Thanks

This is really curious, tbh I'm not an expert around that subject, idk what's wrong with this binary...
Hopefully someone who knows more may help you with that. Have a nice day
This is because the binary you are trying to execute was compiled to run in the Android context, but you're trying to execute it in the TWRP one. Each binary has a path to a linker used during execution. The problem is that it refers to a linker that doesn't exist in TWRP.
Suppose we want to execte a binary file and obviously we can't:
Bash:
x00h:/ # /system/bin/awk
/sbin/sh: /system/bin/awk: No such file or directory
Let's take a look to its linker:
Bash:
x00h:/ # strings /system/bin/awk | head -n 1
/system/bin/linker64
Then, you will actually discover that it's sym linked to a linker that is available only when Android is running:
Bash:
x00h:/ # ls -ald /system/bin/linker64
lrwxr-xr-x 1 root shell 38 2009-01-01 00:00 /system/bin/linker64 -> /apex/com.android.runtime/bin/linker64
Since TWRP comes with its linker in /sbin/linker64, we can sym link it to /system/bin/linker64.
So, the hack:
Bash:
x00h:/ # mkdir -p /apex/com.android.runtime/bin/
x00h:/ # ln -s /sbin/linker /apex/com.android.runtime/bin/linker
x00h:/ # ln -s /sbin/linker64 /apex/com.android.runtime/bin/linker64
Retry, and it works:
Bash:
x00h:/ # /system/bin/awk
usage: /system/bin/awk [-F fs] [-v var=value] [-f progfile | 'prog'] [file ...]
Pray to God the TWRP's linker will be compatible and do the job (most binaries works fine), but sometimes you may get CANNOT LINK EXECUTABLE.
