Execute a script in /sdcard location on termux via adb without physical access to remote android device

[tathastu871]

intent.setClassName("com.termux", "com.termux.app.RunCommandService");
intent.setAction("com.termux.RUN_COMMAND");
intent.putExtra("com.termux.RUN_COMMAND_PATH", "/data/data/com.termux/files/usr/bin/bash");
intent.putExtra("com.termux.RUN_COMMAND_ARGUMENTS", new String[]{"/storage/emulated/0/Downloads/Folder/ShellScript.sh"});
intent.putExtra("com.termux.RUN_COMMAND_WORKDIR", "/data/data/com.termux/files/home");
intent.putExtra("com.termux.RUN_COMMAND_BACKGROUND", false);
intent.putExtra("com.termux.RUN_COMMAND_SESSION_ACTION", "0");
startService(intent);

can someone provide adb am start intent command for this.
after installint fresh termux i want to execute certain command in termux without opening termux directly from adb pc

on remote system i have termux insyalled freshly and it has setup.sh in /sdcard
device has adb enabled
i want to
cp /sdcard/setup.sh $HOME/ and bash $HOME/setup.sh
from adb shell without actually opening and typing in termux as it is on remote device i dont have physical acces to
(its a fresh install it doesnt have sshd installed or configured so its not an option)
on non root device with non debug termux build

i have seen mixplorer app to run termux commands from app itself
can i do same with adb

[agnostic-apollo]

The adb shell user does not request RUN_COMMAND permission, so it cannot send RUN_COMMAND intents. You could use run-as command over adb if using github debug builds (not F-Droid) or if you have rooted your device, then can send intent with su inside the adb shell.

[tathastu871]

lets say i install debug build on non root device
can you give me adb run-as command to fulfill my need

also can debug build be autoupdated from fdroid. or i have to update it manually

[agnostic-apollo]

Note that it is not safe to run scripts from sd card since other malicious apps could modify the scripts, allowing them to run code in termux or root context. Use run-as directly.

will above script work in cygwin.
but how to execute setup.sh i have. it just has some apt commands and cp and tar and netcat commands
cat i just
cat heredoc all those commands as shown in above script.

eg

termux_package_name="com.termux"
termux_activity_name=".app.TermuxActivity"

termux_init_command="/system/bin/sh -c 'TERMUX__ROOTFS=\"/data/data/$termux_package_name/files\""
termux_init_command+="$(cat <<'EOF'
apt update -y
tar -zxvf /sdcard/file.tar.gz
)"

[agnostic-apollo]

cygwin or WSL bash shell should work.

The script should likely work. Use apt-get update -y || exit 1 instead of apt since apt should not be run in scripts.

#2652 (comment)

Some commands may require LD_PRELOAD, so will require starting a new termux bash shell to run the commands.

can dev give a common adb shel pm or adb shell appops
command to give all necessary permissions that termux.apk require
including
draw over other apps.

i tried to extract permission from manifest and supply them to xargs -n1 adb shell pm grant
but java exception errors occur
just want to install

common script to
1)install termux.apk over adb
2)grant all permission including exclusive permission that can only be granted by adb like appops
please. thanks in advance

[agnostic-apollo]

For draw over apps, run adb shell "appops set --user 0 com.termux SYSTEM_ALERT_WINDOW allow"

For storage, run adb shell "pm grant com.termux android.permission.READ_EXTERNAL_STORAGE; pm grant com.termux android.permission.WRITE_EXTERNAL_STORAGE"

For disabling battery optimizations, run adb shell "dumpsys deviceidle whitelist +com.termux"

are above only adb grantable permission or are there many other in manifest.xml

termux_package_name="com.termux"
termux_activity_name=".app.TermuxActivity"

termux_init_command="/system/bin/sh -c 'TERMUX__ROOTFS=\"/data/data/$termux_package_name/files\""
termux_init_command+="$(cat <<'EOF'
apt update -y
tar -zxvf /sdcard/file.tar.gz
)"

is above script correct as i understand. will it work in cygwin a it is

[agnostic-apollo]

Some are automatically granted by android, some require adb or root like READ_LOGS, WRITE_SECURE_SETTINGS, DUMP, PACKAGE_USAGE_STATS.

[tbultel]

Thanks for the script that uses "run-as"
However, it fails because it cannot find termux.env, that seems to be nowhere on the filesystem.
I am using termux-app_v0.118.0+github-debug_universal.apk
Waiting for someone's answer about this, I am digging in the sources to find out why.

[agnostic-apollo]

It's not in 0.118.0, use latest github actions builds.
