[UTIL] a2sd Updated script w/ error checking! 10/12/09

**New version in the works. See last page for my post**
**Updated 5:51pm CST**
-Made sweeping changes to the script. Thanks Farmatito for the suggestions. Output from script also goes to adb logcat
-See script for additional changelog
**Updated 11:00am CST**
-Changed a couple "cp" commands to "ln" as this is a smarter way of doing it. Script has been updated and re-uploaded
After having issues with the current a2sd script floating around (under certain environments the script would erase all user & system apps) I decided to update it so that there is proper error checking, logging, and back-out procedures on failure. The log is stored in /data/a2sd.log so if you get stuck at a black screen or it won't boot, now you can check the log and find out where its failing! By the way, if your phone won't boot or you have a black screen obviously the only way you can read the log is by connecting the phone to a pc and using adb shell cat /data/a2sd.log .
Anyways here it is, enjoy.
Procedure
Code:
adb remount
adb shell cp /system/bin/a2sd /system/bin/a2sd.bak
adb shell push a2sd.txt /system/bin/a2sd
adb shell chmod 777 /system/bin/a2sd
adb shell reboot
Everything should work like before. But you can rest at night knowing if your phone won't boot you now have a way to know if it was related to a2sd and what the cause was
**NOTE: If you get stuck at the boot screen it's probably b/c your /system/sd partition is failing the fsck. You should probably fsck it on your own to fix any corruption. If you don't want the fsck then comment it out of the script.

Very cool, lets hope a developer picks this up and uses it.

I could toss this in my next build if the masses like it (sure they will)

I was going to read through this and give a full opinion but it is too long for me to do it this late. My eyes are crossing trying to read it. But at first glance it looks good (logs are always good right ). And I've never seen shafty not do good work. I'll try to look it over in full tomorrow. Plus you've inspired me to try to think of same way to contribute to this file. So now I have to put that on my todo list.

The more the merrier. It's too bad everyone doesn't have bash installed or we'd be able to take advantage of all the features bash includes (functions, advanced iteration loops, arithmetic).
That would be on all the ROM devs to include it though. Oh and I'm a UNIX Admin so writing shell scripts is like 60% of my job. We try and make our lives easier by writing scripts to do the work for us

I figured you did something like that. Your scripts are always good. I've learned a lot from reading through stuff that you have posted. I wish I had your experience with it. I always have to fumble through to find the right syntax to do what I want to do.

Ya I started out fumbling around just as well. Keep at it and if you ever have any questions about how to do something feel free to PM me. Shell scripting, among the other 10 programming languages I code in fluently, come second nature after years of coding in them. Java/C/C++/Sh/Bash/Lisp/Javascript/Html/Php/Jquery.

Sweet, i will probably take you up on that offer sometime. I have a question about running e2fsck. I always run it with the -f option because it seems like it never finds problems unless they are really bad if I don't. Would there be a problem running it in your a2sd with -fy? I've always wondered why no one uses the -f option.

Well there's two sides to this. One could argue we should force a fsck at every boot, and then the other side is to let Android mark the partition as dirty so fsck will run only when needed. Normally the filesystem is supposed to be marked dirty if in fact it is dirty.
So if we force a fsck at every boot then that would add to the boot time of the OS but then again would ensure the filesystem isn't corrupted. It's really personal preference. It breaks down to "Speed of boot" vs "filesystem integrity"

I can't even find a2sd in cm4.1.999. Seems to have gone missing. Anyone know if it exists, and if so, where it's at?

That's where it should be and used to be. I looked in the original zip and it's not there either. Checked sbin and xbin and other places where it also shouldn't be, and can't find it...weird.

Perhaps it was integrated into the swap file. And I don't mean swap file as in the literal swap file. I mean /system/bin/swap which is a conf file & shell script in one. I would check there to see if it was incorporated in there.

Hi,
just some comments about the "monster" a2sd script. ;-)
Hope they will help you to imprrove it further.
I would suggest to change the logging so that
it could be seen during a adb logcat of the boot process, from:
echo "Beginning a2sd `date`" >$LOG;
to e.g:
echo "Beginning a2sd `date`" | busybox tee -a $LOG;
(LOG must be initialized if it not exists)
Line 40:
e2fsck -y /dev/block/mmcblk0p2;
if [ $? -ne 0 ];
then
echo "Fail" >>$LOG;
exit 1;
fi;
else
echo "Ok" >>$LOG;
fi;
# set property with exit code in case an error occurs
setprop cm.e2fsck.errors $?;
Setprop is not executed in case of errors as we do exit. Is this intended?
Line 144:
# don't allow /data/data on sd because of upgrade issues - move it if possible
if [ -d /system/sd/data ];
then
echo -n "Found /system/sd/data which is a no-no, removing: " >>$LOG;
busybox cp -a /system/sd/data/* /data/data/;
busybox rm -rf /system/sd/data;
echo "Ok" >>$LOG;
fi;
I suggest cp -ap to preserve permissions and ownership of the copied files
I suggest to mv /system/sd/data to /system/sd/data.bak if cp fails
rather than rm all the data
Line 195:
if [ `ls -l /data/$i/ | wc -l` -ne 0 ];
then
echo -n "Moving /data/$i: " >>$LOG;
busybox cp -a /data/$i/* /system/sd/$i/;
if [ $? -ne 0 ];
then
echo "Fail" >>$LOG;
busybox umount /system/sd;
exit 1;
else
echo "Ok" >>$LOG;
fi;
fi;

Line 206:
echo -n "Deleting contents in /data/$i: " >>$LOG;

Line 329:

Unfortunately during boot anything thrown to console is not caught by adb logcat, BUT! You gave me a good idea, it will now look like this

Added.
Thanks for all your suggestions, I will re-upload a new version in an hour or so soon as I get a chance to change the echo commands to use logwrapper. Well I'm keeping the existing echo commands which spit output to my log but will also add another which will spit output to logcat.

I take it back, after having suffered yet another file system corruption on my /system/sd partition I'm putting that darn "-f" in there. I'll re-upload a new copy with other changes shortly

REQUEST/IDEA for a safety script for tweaking/OC

I had an Idea for a script that would run at bootup, and if a certain variable had a "value" of NOT 1.
then the script would change the CHMOD of a userinit.sh located in the sd-ext from 050 or 777 to 750 then it would change the variable "value" to 0 were it would stay untill another script that runs at shut down or reboot setts the variable to 1 and changes CHMOD back to 050 or 777 so that the userinit.sh is not run.
That way if a change is made during operating the phone that causes the phone to crash with out shutting down properly the script runs which causes the userinit.sh to run and "resets" userinit.sh values to a "default". Otherwise if shut down properly nothing happens.
This could be expanded on to include repairing the EXT or clearing some special cache or other stuff I am unfamiliar with but that you might want to run after a crash.(like logcat?)
any way what do you think? any promise?

I think, for overclocking purposes anyway, making the userinit.sh unrunnable would make the phone break immediately, as I think it would go to the highest available frequency. However, I like the idea, though I'm not sure how to run scripts on shutdown. I think for overclocking, it would check if the shutdown was clean on startup, and if not change the applicable line to the next lowest number, which it would get either from a seperate file or maybe it could be stuffed in the script itself. (Just my somewhat uneducated thoughts)

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

most rom devs/tweakers launch userinit.sh by calling it with a sh
e.g.
/system/bin/sh /system/sd/userinit.sh
so it will still run !! ( as init doesn't care about permissions, it is god )
don't believe me?
Code:
echo "echo I ran" > /data/test.sh
chmod 000 /data/test.sh
sh /data/test.sh

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

And I know that most roms now have a script called something like in /system/etc/init.d/20userinit that runs at startup and checks to see if a userinit.sh is present in sd-ext,if so it runs it.Also I noticed that the script can be there but if it is CHMOD to 777 it wont run. This is the "Reset script" Set to restet to something you like and run other tasks to help Fix/Diagnose probs.
The OC changes would be made from a different script such as 86supersettings
Or a userinit located in system/sd maybe ?
The thing is making sure one is read before the other.
Any way I probably will just learn the language better and do it from recovery console.
Thanks again

chmod 777 makes it rw and executable by everyone!!!!!!!!
have a look here
http://www.comptechdoc.org/os/linux/usersguide/linux_ugfilesp.html
but as I mentioned above, init ( the initial progam runs as root and doesn't care about permissions, ( it wouldn't be very good at doing initialising the system if it had to seek permission )

Yea your right. Well I said I wasn't that good at this linux stuff! Now I Proved it.
Any way as you can see this is more of a request..... I still think it's a good Idea.
Thanks for your help FireRat.

I understand how I could manualy Replace the modified script with a default one that was on my sdcard from within recovery after a faild OC change...but..
Are you saying I could actualy modify the original script from recover? Do you have any info on how? A link?

If you have RA-Recovery, adb works, so you can pull/push the userinit.sh script. You can also enter the terminal and use vi to edit it from recovery. You may have to mount the ext partition first, but that's pretty easy. "mount /system/sd" will do it, if /system/sd doesn't exist, "mkdir /system/sd".

Ok, Thanks that makes sense. I'm still learning adb though. And I tried vi once before with no luck. But now I know what to learn about.
Thanks a lot I appreciate it.

I am going to use the beta boot up script from ZKX called 86Supersettings, but I could use a userinit/user.conf like most do. Correct?

OK. I guess I meant both together. I would use the user.conf to make tweaks. Then have to modify the userinit.sh with the part you made. Something like.

well, in practise it doesn't matter
the file extension is only for use humans, if I'm looking in a directory and I see .conf I expect it to be a configuration file, I see .sh, its a shell script, .py python, pl perl .......

I see. Well Thanks again for your help. Your script does work. I tried it. crash on purpose.
I still have a lot to learn.

Folks;
1) If you're OC'ing via SetCPU, remember that this doesn't change the recovery kernel, and you can uninstall SetCPU from Recovery. From there, all you need is a "safe" userinit.sh.
3) If you're OC'ing via userinit.sh -- same deal. Your phone crashes on you and you just edit it to a safe config from recovery.
Tweak away.

This is what I ended up with

Named 86supersettings so it runs after userinit.sh if one exists.
I put some Led indicators in so you can tell if it ran right at boot up. (about all I did besides copy and paste) Thinking about adding some other stuff like repair ext, or some kind of log to help me see what happed... any suggestions.

OK, here's another Idea for another safety feature...
I would like to "hard code" a temp fail-safe in to the code. I would like to get rid of SetCPU and when OC-ing it's nice to have a temp failsafe.SHUTDOWN!LOL
Any way I guess I would just add a few lines to some existing script in my phone?.... Any suggestions.
Thanks for your time.

Tizen chrooted for Android

Hello xda-developers!
I'm trying to port Tizen for samsung wave 1.
But now I'm doing some research.
This thread will be my research on doing a chrooted scripts and try to boot a Tizen 2 Alpha working through vnc-viewer.
I'll write here my scripts for everyone to test it.
After these scripts an app. But now scripts.
This thread will be updated everytime I get a spare time to write it.
Thanks!
Tutorial:
First download the image from the torrent file.
Copy it for your extsd or sdcard phone/tablet.
It's to copy the image file from Tizen 2 Alpha for these two places.
And on terminal emulator run the tizen_run bash file.
Test it and I will test it too as I'm writing this tutorial and post.
Rename the script tizen_run.sh.txt to tizen_run.sh
Thanks !

what can we do with this file?

In badadroid vnc-viewer and terminal emulator You can run Tizen under android.

sorry for the noobs questions, but how??
Edit 1:
I saw your tutorial just now, but I did not understand what to do in the terminal emulator?

There's no problem at all.
You need to copy the code into a file bash(.sh) with the name tizen_run.sh
Then in badadroid run it an app called terminal emulator to get into vnc-viewer.
As a loopback image inside android.
I'm trying to run it as an application like linuxonandroid.

I think I am not smart enough to do understand you..
But thanks anyway..

Okay.
I'll upload here the file to run on terminal emulator.

I'm testing the app for android.
I'll upload it here.

Something wrong.There are no permission to tizen_run.sh
I can't test

New link for image tizen:
http://tizen-kernel-s8500.googlecode.com/files/tizen.7z.001

Try this command:
sh tizen_run.sh
or
./tizen_run.sh

Copied Tizen.img (latest one) to sd card
Copied tizen_run.sh to sd card
Then on Android (Nand Ver.) Emulator tried
sh tizen_run.sh ---> no such file or directory
./tizen_run.sh ---> not found

I'm going to check it out.
type this on terminal emulator:
cd /mnt/extsd - if exists
cd folder "where the Tizen.img and script is located"
then
sh tizen_run.sh
or
./tizen_run.sh

I'll post a new file.
To see what happens.

in the first topic i have a txt file rename it on linux.
mv tizen_run.sh.txt tizen_run.sh

news??

Sorry about not saying any news.
Next week another build and a better script with an app for badadroid.

[SCRIPT][UPDATED 03.26.14] Fix Lag, Defrag/Free Memory with |=>TrimDropOff<=|

Updated 03.26.14 - Released v2.1 - bug fixes and code cleaned
Introduction:
I am by no means a developer. I am just an android enthusiast who has learned a bit of bash. The reason I made this script was that settings>>wifi>>advanced was not promptly turning wifi off when my device would sleep; sometimes it would not turn off at all. So I figured since I am making a script to resolve this issue I might as well add a couple of other functions as well. To this end I noticed some people saying THIS APP was helpful and I missed the Flush-O-Matic script from V6 SuperCharger so I added fstrim and drop_caches=3 to the script.
Click to expand...
Click to collapse
What will this do?
The script will allow you to sync wifi, fstrim, and/or drop_caches=3 with sleep and/or it will allow you to schedule fstrim and/or drop_caches=3 using crond. The scheduling option can work on either a hourly (you can choose to run desired programs every hour on the hour, every two hours on the hour, every 3 hours on the hour, etc) or daily basis (you can choose to run desired programs at a given time on the hour).
Both the sync and schedule options will load themselves in to memory each boot and each time your device goes to sleep and/or when scheduled the scripts will depending on your options: (1) sync your data so as to ensure no data is lost; (2) TRIM your /system, /data, and /cache partitions; (3) DROP CACHES = 3; and (4) turn off wifi.
In addition, there is also an on-the-fly script to manually trim partitions and drop caches when desired.
Click to expand...
Click to collapse
Benefits:
Reduce lag/improve i/o efficiency (see THIS and THIS).
Although android automatically invokes fstrim when certain conditions are met, these criteria could seldom if ever be met depending upon your usage style. The init.d script should ensure fstrim is invoked more frequently for most users.
Should use less ram than apps that perform similar functions (I say should because I have never used such apps, but I imagine they consume more that .2-.5 mb of ram).

Requirements:
root
init.d
busybox
fstrim (should be in all nexus 4.3+ roms)

Warning/Disclaimer:
Although these scripts function as intended on my device – Nexus 7 (2013), SlimKat (weekly), ElementalX...Use at your own risk. Neither I nor XDA are responsible for any possible deleterious effects.
Click to expand...
Click to collapse
Known Issues/Bugs:
If you use the sync option, scripts with a lower priority than Z99 will not execute.
The log files don't always display as intended...dunno why...any help/suggestions would be appreciated.
Let me know if you find any others .

Install, Usage/Verification, & Uninstall:
Install -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
make a nandroid backup
download the zip (<<NOT flashable) attached to this post
extract the zip’s contents
if you were/are using the first version of this script manually delete: /etc/init.d/07TrimDropOff, /data/TrimDropOff_Awake.log, and /data/TrimDropOff_Sleep.log
run TrimDropOffInstaller with superuser permission via terminal or script manager.
follow the scripts prompts
reboot
enjoy
Usage/Verification -
Assuming you have followed the install procedure, next, put your device to sleep and then wake it if you are using the sync option.
Now check the various logs in /data/TrimDropOff. The logs will show the time, the script’s PIDs, the path of the PIDs (just to double-check the PIDs are correct), the ram used by the PIDs, action(s) preformed (amount trimmed from each partition and/or if drop_cahes was run), or errors.
If you want verify manually via terminal do [pgrep -f TrimDrop] for the sync option or [pgrep crond] for the scheduling option to get the PIDs, do [cat /proc/PID/cmdline] for each PID to verify it truly belongs to Z99TrimDropOff or crond, and do [dumpsys meminfo | grep PID] for each PID to verify ram usage (this command will yield duplicates, which can be disregarded and may output undesired additional results, which can be filtered by looking through the results for the relevant PID).
To use the on-the-fly script to trim and/or drop as desired, in terminal do [su -c trimdrop].
Should you want to reconfigure your setup, uninstall before reinstalling to avoid potential issues.
Uninstall -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
Rerun TrimDropOffInstaller with superuser permission and use uninstall option at the beginning of the script.
Reboot and all will be back to as it was before.

Changelog:
v2.0
made in to installer script
added cron options
added bootloop precautions to the init.d scripts (should make it compatible with all devices that meet the requirments)
the on-the-fly script, trimdrop, now allows user to choose fstrim and/or drop_caches=3
added more syncs to further ensure no data is lost
a bunch of other stuff I probably forget
v2.1
bug fixes - fixed issue if using only sync option (missing directory); fixed display of irrelevant errors in uninstall routine
cleaned code a bit (reduced redundancy)

Big thanks to @zeppelinrox, @dk_zero-cool, & @gu5t3r for their contributions to portions of this script (see the code of my other script SwapItOn for detailed citations).
Much thanks to @mdamaged for spotting the issue with sync init.d script and his note regarding syncing data.

Don't forget to click THANKS and RATE 5 STARS if you found this useful :highfive:.
peep my other script SwapItOn
Update to v2.1 if you were only using the sync option.
If you were using both the sync and schedule options or only the schedule option there is no need to update; the bug I found would not effect you.​

reserved...on the off chance it will be needed

Thanks, sounds interesting. I'm assuming the zip can be flashed right after flashing a new rom?

Oh, thanks

Is compatible with custom kernel? Franco in my case
vía n7II r-paco

Will performing trimming operations too frequently cause additional flash memory degradation?

As you were informed the zip is NOT flashable. If there is sufficient interest (say a 100 downloads) I'll make it flashable/aroma.

Yes, it should be compatible...the fstrim utility is part of the rom (it should be in all nexus 4.3+ roms).

No, to my limited knowledge it should not be harmful (in fact it should increase lifespan - google "fstrim lifespan"). Did a quick google search but could not find anything definitive/reliable regarding frequency...what I did see seemed to suggest 'no' though.
If you are concerned about the frequency, you could not install the init.d script and just use the on-the-fly script, trimdrop, to trim on-demand. Should there be interest and if I have the motivation and time, I have been thinking about making this in to an installer script and/or aroma zip with cron-based options so it could be scheduled hourly, daily, or weekly.

Scheduling options would be awesome!

Seems there is a decent amount of interest (almost 100 downloads already ...thanks peeps), as such I'll add options and make things more configurable.
Regarding scheduling, I was thinking of doing hourly, daily (with ability to choose time), and weekly (with ability to choose day and time) options. Would every other hour or some other setting be desirable?
Regarding installation, what would be the preferred method, an installer script (e.g. V6 SuperCharger) or AROMA? Flashable zips would be another option, but would have less options/be less configurable.
Gimme some feedback and I'll put something together in the next week or two depending on work and my motivation .

wasn't this a nexus 7 2012 issue and fixed in the new version 2013?

My 2 cents:
I would choose a daily option for my device.
I prefer Aroma over a script, but if you cannot get the customization you want with Aroma, then by all means go with a script.
Thanks again for the script and willingness to make it even better!

Thanks for the scripts, I time my startup, and this improved startup time by about 3-4secs, among other noticible improvements, apparently the stock OS does not run fstrim enough, initial operations freed several gigs on the data partition, and hundreds of megs on the others...

Im going to turn this into a cron job, that will take care of scheduling, unless anyone else gets there first ( please lol )
Will give it a go in its present form, whats its resource footprint just sitting there waiting for screen off ?
Can we trigger the action from the screen off event ? or some other interupt type way ?
Great script by the way, your bash is damn site better than mine, jealous lol

Yes, I think this is true to a degree...it was more of a problem on the 2012 and other nexus devices. See the links in the OP for the conditions that need to be met for fstrim to autorun...for some users (myself included) the conditions will seldom if ever be met. Also see @mdamaged post; I get similar results the first time fstrim is initiated by my script after each boot...subsequent runs normally only frees up memory on /data.

See the first post on this page and my response to @creeve4 and @imfun in this post. I will make an AROMA package with cron options for fstrim and drop_caches=3.
However, should you feel ambitious and beat me to it, props to you...I will give you full credit in the OP and link your post as the d/l source so you should get the 'thanks' too.
Regarding triggering with screen on/off or some other event: It can probably be done, but I it's beyond my knowledge (screen on/off was actually the first trigger event I looked in to using, but despite fairly extensive searching I could not find how to detect it).
Regarding resource footprint: Read the OP (usage section) it explains where to find the log which contains this info and how to do it via terminal (should you not trust me )...also see OP (benefits section): in all my testing I have never seen it use more that .8 mb, but most of the time it is less than .2 mb.

Okay will get to making an AROMA package...it will be my first, but it looks easy enough :fingers-crossed:...gimme a week or two to put it together and fully test.

Can't wait already, because after whole day or two, hard usage of my nexus 7 tablet, the tablet starts to get laggy. I can see this on web browsing, touch press delay time, and onyl rebooting seems to help... Hope after istaling this will solve the problems

ohhh no dont want any credit lol lol, i have turned it into a cron job quite simply by adding it to the cron initilising script

For an aroma script you will prob have to stick the file in /system/etc/cron/cron.hourly, daily, weekly and just give peeps that choice, will be most simple way. Ps not a fan of aroma lol

Ok, I should have spotted this issue right away, but did not, so here goes. It seems the use of while loop in the script in the OP causes any scripts with a lower priority in init.d to never get ran, if the script in the OP is the only one in your init.d this does not matter, nor should it matter if you have at boot script with a higher priority (they get ran before the OPs script).
I run the ElementalX kernel which depends on a init.d to initialize some parameters for the kernel, with this script in init.d they never get initialized, in my case this resulted in some things not 'taking' such as the battery life extender, which on my device, is set to stop charging at 4100mv, however, since the while loop kept the ElementalX init.d from running, it kept charging to ~4300mv, this is how I noticed (actually none of my settings wrt ElementalX were being initialized, but this symptom was most pronounced).
A simple fix would be to move up the priority of the ElementalX init.d script, but this would have to be done after each flash, and frankly since I run Tasker anyway, I saw no need for this, what I did was remove the OPs script from init.d and simply made a very simple task in Tasker to run /system/xbin/trimdrop when display goes off, it could just as easily be a time event.
Anyways, hope that helps someone who may come across this with other kernels, or other at-boot scripts which depend on being ran before the OPs script.
Again, thanks to the OP for his work. Also, I added another sync just before the drop caches, since the state of dirtyness could change after the fstrims.

Using command echo .sh file doesn't work in recovery

I'm trying to understand why using echo command in sh file doesn't work in recovery.
I've made a flashable zip with 7-zip, it contains a shell script.
The updater-script is
Code:
ui_print("");
run_program("/sbin/busybox", "mount", "/system");
run_program("/sbin/busybox", "mount", "/data");
package_extract_dir("test", "/tmp");
set_perm(0, 0, 0777, "/tmp/test.sh");
run_program("/tmp/test.sh");
delete_recursive("/tmp");
unmount("/system");
unmount("/data");
and my test.sh is like this :
Code:
#!/sbin/sh
rm -rf /system/app/YouTube
echo "Delete Youtube"
test.sh deletes Youtube folder but echo command doesn't work.
I use TWRP 3.2.3.0 recovery

Echo is a command for windows command line. In recovery you use: ui_print("<message goes here");
In recovery the language used is called Edify.

Use Linux commands only. Echo is for Windows command line.
I don't have the skills to help you but googling "Linux commands for console" should help

So googling linus commands but I don't find how to use echo in a sh file in recovery.
If you have time try yourself echo command .
I've no idea why it doesn't work.

ECHO is a command for windows command line dude! Why do you insist on using echo? Echo is for windows command line? Got it now?
You need to use other commands according to the system you are using. and in android you use bash language on .sh files!

Every programming language uses its own commands...
Maybe because of that?

After some research
i change a little my script to see if command echo works
code in updater-script
Code:
ui_print("*************************");
ui_print("sh10");
ui_print("*************************");
unmount("/system");
unmount("/data");
#ui_print("-- Montage partitions...");
run_program("/sbin/busybox", "mount", "/system");
run_program("/sbin/busybox", "mount", "/data");
package_extract_dir("test", "/tmp");
set_perm(0, 0, 0777, "/tmp/test.sh");
run_program("/tmp/test.sh");
#ui_print("Extracting files ...");
#package_extract_dir("system", "/tmp/update");
#set_perm(0, 0, 0755, "/tmp/update/myscript.sh");
#run_program("/tmp/update/myscript.sh");
#delete_recursive("/tmp*");
ui_print("END OF PROCESS");
ui_print("*************************");
unmount("/data");
unmount("/system");
code in test.sh file
Code:
#!/sbin/sh
#echo on
#function to display commands
exe() { echo "\$ [email protected]" ; "[email protected]" ; }
OUTFD=$2
ui_print() {
if [ $OUTFD != "" ]; then
echo "ui_print ${1} " 1>&$OUTFD;
echo "ui_print " 1>&$OUTFD;
else
echo "${1}";
fi;
}
#rm -rf /system/app/YouTube
echo "hello world !, using echo" >tong.txt
exe echo "Delete YouTube, using exe echo"
echo "Delete YouTube, using echo" >>tong.txt
printf "hello world, using printf" >>tong.txt
cat tong.txt
ui_print "hello world! using ui_print"
echo command doesn't print on screen but it creates tong.txt and pass in results.
We can see it works in recovery.log

You are probably going to have to go in a little different direction. See this thread where update-binary is used in place of update-script.

Thanks, but this isn't exactly what i'm looking for even if it's very interesting.
I would like to know how to display on recovery screen
I tryed with echo command but it doesn't work
For example running this script in sh file on recovery TWRP
Code:
#!/sbin/sh
csc_id=`cat /efs/imei/mps_code.dat`
echo "==== Your active csc is $csc_id ====="
echo do displays this
==== Your active csc is BTU ====
on recovery screen
but not displays anything.
Is there a way to activate it ?

Echo has never worked on my phones. ui_print works on my pixel and pixel 2. It stopped working on my pixel 3 XL but that is because I haven't found a way to mount system using toybox. Pixel 3 XL won't mount using BusyBox.

Most everyone uses TWRP. I believe for recovery screen, echo must be passed on to ui_print. Try this for an explanation:

That works on my pixel and pixel 2 but not my pixel 3 XL. But on my pixel 3 XL I also have to use toybox to mount instead of BusyBox
run_program("/sbin/toybox", "mount", "/system");
