I'd like to set up a small bash script, which I'll write on my PC but then run from my Android phone. Objective: - When my phone connects to the Wi-Fi at home (detection possible via the SSID), the script should do the following: - When I get home, my phone connects to the Wi-Fi. - It then checks whether the static IP of my NAS is responding. - If so, it connects to the NAS via SSH. - It only copies photos and videos taken more than 2 weeks ago. - It copies them to the NAS, in a defined folder. - It deletes the source files from the phone if the copy went well. There are lots of ways of doing this, but I'm trying to find out what the best practices are for this type of automation on Android. Which applications do I use? Which way do I do it? etc. I'm open to any kind of recommendation, as long as it's good practice and maintainable! It must be professional.

I have a problem with USB tethering on my rooted Nougat phone (LineageOS). After some time phone stops USB tethering. To fix that I run the following script like this: adb shell su nohup sh tether.sh & exit exit tether.sh #!/system/bin/sh service list while true; do if ! pidof -s dnsmasq > /dev/null then echo -n "Connectivity lost at " date -u +%FT%TZ echo "Waiting 3 seconds..." sleep 3 echo "Calling ConnectivityManager.setUsbTethering(false)" service call connectivity 33 i32 0 2>&1 sleep 3 echo "Calling ConnectivityManager.setUsbTethering(true)" service call connectivity 33 i32 1 2>&1 echo "Waiting 3 seconds..." fi sleep 3 done Problem: If I use nohup my call to service call connectivity fails with service not found. And I put service list on top of the script which returns Found 0 services:. However the same commands work when ran directly from adb shell; su. Why service call doesn't work inside this background script? Does it need the same tty to work?

So, I'm making a little batch script to be able to automate the whole process of flashing new roms for my Galaxy S6. Since its screen is broke, I have to do everithing manually from the adb shell, and since i'm having so many troubles with all the roms, I decided to make a little script to make my life easier. This is what I got so far: @echo off setlocal enabledelayedexpansion REM Factory settings echo Formatting to Factory Defaults adb reboot recovery adb wait-for-usb-recovery adb shell twrp wipe cache adb shell twrp wipe dalvik adb shell twrp wipe data adb shell umount /sdcard adb shell umount /sdcard adb shell umount /data adb shell umount /data adb shell mke2fs -t ext4 /dev/block/platform/15570000.ufs/by-name/USERDATA adb shell reboot recovery adb wait-for-usb-recovery REM Rom Flashing Section set argCount=0 for %%x in (%*) do ( set /A argCount+=1 set "argVec[!argCount!]=%%~x" ) echo Wiping /system adb shell twrp wipe /system for /L %%i in (1,1,%argCount%) do ( adb wait-for-usb-recovery echo Flashing "!argVec[%%i]!" adb shell twrp sideload adb wait-for-usb-sideload adb sideload "!argVec[%%i]!" echo "!argVec[%%i]!" flashed echo. ) REM Debug enable adb wait-for-usb-recovery echo Enabling USB Debugging adb shell mount system adb shell "echo '' >> /system/system/build.prop" adb shell "echo '# Enable ADB' >> /system/system/build.prop" adb shell "echo 'persist.service.adb.enable=1' >> /system/system/build.prop" adb shell "echo 'persist.service.debuggable=1' >> /system/system/build.prop" adb shell "echo 'persist.sys.usb.config=mtp,adb' >> /system/system/build.prop" adb push C:\Users\ffpp2\.android\adbkey.pub /data/misc/adb/adb_keys REM Booting system echo Rebooting into system... adb shell reboot echo waiting for phone to boot up adb wait-for-usb-device echo Launch scrcpy "D:\Users\ffpp2\Documents\Celus\zeroflte\scrcpy-win64-v1.25\scrcpy.exe" Now, I want to be able to evaluate every adb shell ... return code, so if anything happens mid way I can stop execution and I can get to fix what didn't work. I havent been able to find anything regarding if adb shell forwards error codes back to the windows command prompt. Take a look at this: D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell mount /system mount: mounting /dev/block/sda15 on /system failed: Device or resource busy D:\Users\ffpp2\Documents\Celus\zeroflte>echo %errorlevel% 0 D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell ~ # mount /system mount: mounting /dev/block/sda15 on /system failed: Device or resource busy ~ # echo $? 255 ~ # exit D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell cat asd cat: can't open 'asd': No such file or directory D:\Users\ffpp2\Documents\Celus\zeroflte>echo %errorlevel% 0 D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell ~ # cat asd cat: can't open 'asd': No such file or directory ~ # echo $? 1 ~ # As you can see, no error code was returned. And, in theory, it should be returned, since I didnt used the -x argument: Android Debug Bridge version 1.0.41 Version 34.0.0-9570255 Installed as C:\Program Files (x86)\ADB and Fastboot++\adb.exe ... shell: shell [-e ESCAPE] [-n] [-Tt] [-x] [COMMAND...] run remote shell command (interactive shell if no command given) -e: choose escape character, or "none"; default '~' -n: don't read from stdin -T: disable pty allocation -t: allocate a pty if on a tty (-tt: force pty allocation) -x: disable remote exit codes and stdout/stderr separation emu COMMAND run emulator console command ... Has TWRP anything to do with this?

I have an old stock Android 5.1.1. It has custom twrp recovery and is rooted. I have the stock boot.img file and am able to edit the init.rc and repack and flash it back with fastboot flash boot boot.img. No problem there. And after flashing the boot.img, I can cat /init.rc and can see the changes that I made to run a script from /system/xbin/. However, the script does not execute at all. On the very end of init.rc, I placed this line of code on property:sys.boot_completed=1 start initAsic service initAsic /system/xbin/script.sh seclabel u:r:init:s0 user root group root oneshot disabled The script.sh is already chmod to 755 in /system/xbin/script.sh and in script.sh, there this echo "hello" > /data/local/tmp/file.test iptables -P FORWARD DROP The problem is, it doesn't work. So googling further revealed that I need to set selinux mode to permissive. And so I did with, setenforce 0 It does set SELinux to permissive, however it's only temporary, because on reboot it goes back to enforcing mode. I was wondering if there was any way for me to modify the content within boot.img that would lead SELinux to be permissive always.And also, is permissive mode the real reason why my init script isn't running, or am I doing something wrong?

I'm accustomed to running scripts on boot in Linux, but I'm not sure how to do this in Android. I'd like to start my SSH daemon on start, so I'll always be able to connect. How can I run an arbitrary script on Android boot? It'd be preferable to do this outside of Dalvik.

I'd like to know if there's any way I can change the date settings on startup without root access. I'm using Urovo DT50 and Honeywell EDA71, both with Android 10. The problem is, these devices (and there's a lot of them in my workplace) connect to WiFi through the use of certificates, which have a period of validity. For some reason after a loss of power (changing the battery or just discharging it to 0%), the date in Android resets itself to 01.01.1970, resulting in the device being unable to connect to the network. I want to "automate" clicking through the settings and changing the date by hand. Or if there's a way to change the default date the device goes back to, that could also fix the issue. As I mentioned, I don't have root access so I take into account that it might be unachievable, does anyone has any ideas?

Lately I've been playing around with .sh scripting in Android. At first I used BusyBox and it's integrated scripting utility, though I quickly realised that coding on the phone isn't the best, so I switched over to my desktop and started using ADB to push my scripts to my device. It all worked well for about two weeks, until recently the exact same scripts that used to work perfectly, tell me some : not found: syntax error: '{ Error. I've copied the exact same code from my script and used BusyBox to create it for me, and that way it works just fine. So the code is fine. After some digging, I think it's either because of permissions, because of encoding possibly, or also because of the location of the scripts. I've tried many different locations (because I want to be able to run the scripts without root), and ended up choosing /storage/emulated/0. If I understood correctly, this is a symlink to the internal storage, which is read/write-able without root. But maybe sometimes executable and sometimes not? I don't know. So my question is as following: **What is the best location on an Android Device to run scripts without root from?** Preferably a path that works on any android device. Info: - Rooted Samsung S7 SM-G930F - Android 8.0.0 - I'm using #!/system/bin/sh inside the .sh files - I'm running the scripts with sh script.sh - When trying to run it as an executable ./script.sh, I get a Permission denied error. With or without root. PS: And if anyone has a clue to why the exact same scripts stopped working out of nowhere, I'd be happy to know! **UPDATE:** Thanks to @IrfanLatif, I've managed to fix the : not found: syntax error: '{ Error! I was using Visual Studio Code as my editor for the scripts, which was saving them with the End of Line Sequence CRLF, which Android doesn't like. For an easy fix, just change your Line Endings to LF, problem solved. Check the comments out for more info.

This current question is indirectly related to the following other question here: https://android.stackexchange.com/questions/255469/checking-via-a-script-whether-a-given-app-is-prohibited-from-installation-on-a-g I'm running stock rooted Android 11 and stock rooted Android 13 on two different devices. I'm wondering if there's a way that I could write a script that runs on the Android device and which will install a given app from the Play Store. My goal is to initiate the app installation from the Android device without any GUI interaction; *i.e.*, no clicks nor button presses nor any manual operations, and I want this to be able to be accomlished solely within a script that gets executed on the device. In the other question I referred to above, I found out that a slightly different Play-Store-related operation could not be invoked in this way, and that the only way it could be accomplished on the device itself is via GUI interaction ... either manually or via some sort of "uiautomator"-like automation. Is this the same situation here? *i.e.*, is it impossible when running on the device to install any app from the Play Store without some sort of GUI interaction? Thank you in advance.

(NOTE: the text of this question has been updated to make it much clearer than before as to what I'm actually looking for). I'm running stock Android 11 on one device and stock Android 13 on another device. I'd like to write a command-line script (not a Java-implemented app) that can run on both of these systems and on many other Android devices/OS's, and which can check whether or not a given app would be prohibited from installation via the Play Store on the specific device where the script is running. To be clear, I am not simply interested in whether the app *exists* in the Play Store on the web. I'm looking for something more specific: Some apps that exist in the Play Store on the web for general installation might be prohibited for installation on a specific, particular device. This could be for security reasons (*e.g.*, DEVICE integrity is not being reported on the device), or it could be because the device's Android version is too low, or there could possibly be other reasons. In these cases, the app does not even show up in the device's Play Store when searching for it to be installed, although the same app will indeed show up in a Play Store search on other devices that do not have these kinds of issues. I want to be able to somehow query the current device's Play Store installation (not the generic, web-accessible Play Store pages) to see whether the given app might be prohibited for installation on the current device. One example is the Netflix app. If the phone does not report DEVICE-level integrity, the user will not even see Netflix as existing when searching it in the Play Store on that particular device. This is the case I'm trying to find a solution for. For example, let's assume for the purpose of this discussion that the app happens to indeed be Netflix. That particular app's package name is "com.netflix.mediaclient". If my proposed script is named "app-in-playstore.sh", I'd like to be able to do the following, and have the script print either "false" or "true" to stdout, depending on whether or not this Netflix app is prohibited from installation via the Play Store on the device upon which the script is running, or whether its installation is indeed allowed on that particular device ... /system/bin/sh app-in-playstore.sh com.netflix.mediaclient (or perhaps preceded with "su -c" on a rooted device). If the current device is reporting DEVICE integrity at the moment this script is being run, the script should print "true", because Netflix would indeed show up in the device's Play Store as installable. If the current device is not reporting DEVICE integrity at the moment this script is being run, the script should print "false", because Netflix would not show up in the device's Play Store as installable. To be clear, this isn't solely related to Netflix. I'm just using it as an example here, because I happen to know that it indeed will not show up in the Play Store if the phone is not reporting DEVICE integrity. I'm sure there are other apps that are treated similarly, and I want my script to be able to identify these other apps in the same way. Is writing such a script possible? And if so, how could it be accomplished? Thank you very much in advance.

I'm looking for a way to check for my device's integrity level which can be done in an automated way ... for example, within a script. By "integrity level", I mean querying whether my device has "MEETS_BASIC_INTEGRITY" and "MEETS_DEVICE_INTEGRITY". I know I can manually do the following to query that info: To first enable ... PlayStore Options=>Settings=>About ... and then click Play Store Version seven times to enable "PlayStore Developer" options Then, after enabled, I can manually do the following any time I want to see the device's current integrity level ... PlayStore Options=>Settings=>General=>Developer options=>Check integrity However, I'd like to avoid this set of manual steps and instead, return this integrity info via some method which can be automatedly used within a script. Is there any way that I can do this? Thank you in advance.

I have Firefox 94.1.2 on a Pixel 3XL with Android 10. I'm trying to install a user-script extension like Greasemonkey Tampermonkey. addons.mozilla.org shows these are both available for Android: Greasemonkey Tampermonkey When I open the Add-on menu in Firefox, I see one add-on I have Enabled, and about 15 other "Recommended" (not of interest). I find no way to search for additional add-ons in addons.mozilla.org. I found this article that said this issue would be fixed about a year ago, but I'm still not able to install add-ons. This article implies that running Nightly versions of Firefox might allow more add-ons. Is there any other way to install these extensions?

There are a variety of CPU architectures that android systems use such as

-v8a

,

-v7a

,

,

and

. Is there a way for

or any other tool to detect the architecture of a connected device? I have many devices connected to a PC running adb and I would like to create a script so that

can deliver the correct package. For example, I have packages

-v8a.apk

,

-v7a.apk

and

.apk

on my desktop that correspond to their respective architectures as well as tens of android devices that are connected to an

server on desktop. How can I iterate the output of

devices

so that the script figures out the architecture of each android device and automatically install the right apk to each device?

I have Android 10, Samsung a7. I have root by custom firmware + Magisk. I tried to put script in:

/data/adb/service.d/myscript
/data/adb/post-fs-data.d/myscript
/system/etc/init.d/myscript

But it doesn't run. Where I can put my script to execute after boot system? Script to execute:

#!/system/bin/sh

sleep 100

is_charging()
{
    [ $(cat /sys/class/power_supply/battery/status) = Charging ] || [ $(cat /sys/class/power_supply/battery/status) = Full ] || return 1
}

# keep waiting
while is_charging; do sleep 1; done

# charger is disconnected, countdown
sleep 300

# again start waiting if charger is connected
is_charging && exec $(realpath $0)

# else, shutdown
/system/bin/reboot -p charger_disconnected ||
/system/bin/setprop sys.powerctl shutdown,charger_disconnected

I have been searching online on multiple sites and could not find one answer to this question, only found one question online but with no answer. How does the Android recovery update files from an update.zip file using the package_extract_dir(""); code in the updater-script? 1. Does it clear the folder and copy the files in update.zip to that folder? 2. Does it just copy the files over (that don't already exist on the device) and not overwrite any files? 3. Or just copy the files from update.zip and overwrite any previous files? This is using the default Android recovery screen, I am sure it is option 3, but just for anybody asking this question, want to know for definite.

How can I build a code/script to stop infinite scrolling (or scrolling at all) in any app I want to, like YouTube Shorts, IG Reels and Tiktok. Script should not break any app from running at all and other functions should work. Rooting is permissible. I think there would be a need to change some code near to Android base.

What are the first scripts executed by the Android boot-up process before it starts running processes that do not have root privileges?

I want to dump the output of uiautomator dump to a variable and read it from there. How can I edit the below script so as to achieve that? #!/system/bin/sh while true ; do uiautomator dump sleep 1 done

My objective is to write a shell script to periodically turn off and on my phone's flashlight (about 1 kHz or 500Hz). My phone is rooted. So I gained superuser shell access (#) These are the files under my sys/class/leds/flashlight

whyred:/sys/class/leds/flashlight # ls
brightness device max_brightness power subsystem trigger uevent

() I was able to modify the content of the brightness file and was able to manually switch off and on my flashlight. However, I want to periodically switch on and off with a delay and for that, I need a timer trigger. But within the trigger file above, there is no delay section indicated. There was just some contents within the file (no numbers)

whyred:/sys/class/leds/flashlight # cat trigger
[none] bkl-trigger switch0_trigger flash0_trigger flash1_trigger torch0_trigger torch1_trigger switch1_trigger flash2_trigger torch2_trigger dc-online usb-online main-online pc_port-online battery-charging-or-full battery-charging battery-full battery-charging-blink-full-solid rfkill0 mmc0 mmc1 bms-online parallel-online rfkill1

() I was able to clock into a period of about 1-3ms by writing a bash script, that echoes brightness 100 followed by sleep and then echoes 0 brightness Script:

while [ 1 le 100]
do
echo "100" > ~/sys/class/leds/brightness  
sleep(0.001)  
echo "100" > ~/sys/class/leds/brightness)
sleep(0.001)
done  # end

But I want at least a 1 kHz frequency, so a timer is the one, sleep function is not advisable. How can I about attaining my objective?

I'm using cm13 on my OnePlus 3, along with systemless SuperSu and suhide. When I update cm (often), I need to flash both SuperSu and suhide. The problem is that cm comes with root access and when updating, makes a su directory in /system/bin/su that suhide detects so that it won't install. I need to delete that directory in between of the flashes, and I would like to make a script that does that for me when i flash it so that I can flash all files together on update using CyanDelta. I know that this is possible because I have seen other zips that execute command scripts as i flash them.

I have a device connected to a TV, I need that when I start the device it automatically opens the player and plays a video. I thought that I could do the same as linux, writing a bash script, it would be relatively easy and it would start at startup, well linux already has such a startup script. But I can't find the /etc directory. On the other hand, how are the orders of the app? To be able to write it in the script? And your options. Also if there is another option I would like to know it. Thanks.
