termux: running termux via adb without *any* direct interaction with the device?

Question

I know how to open the termux app, run (for example) sv up sshd, and then interact with the Android device via ssh, rsync, etc. This is just an example, and the same is also true for any other termux initiated procedures.

However, to do this, it's necessary to perform that manual open and manual sv up sshd command in termux on the device itself.

I want to be able to perform that initial termux interaction from my desktop computer via adb without any direct interaction with the device itself, aside from plugging in the USB cable.

I have looked for solutions, but it seems like no one has come up with any way to interact with termux except by first actually manually opening that app on the device, which I do not want to do.

However, could I have overlooked something? I'm hoping that I indeed missed something, and that somehow I can start termux-initiated procedures via adb.

Does anyone know how that might be done?

Thank you in advance.

Answer 1

You can use run-as to access your Termux environment from adb without root or ssh.

Run adb shell and then:

run-as com.termux files/usr/bin/bash -lic 'export PATH=/data/data/com.termux/files/usr/bin:$PATH; export LD_PRELOAD=/data/data/com.termux/files/usr/lib/libtermux-exec.so; bash -i'

This will give you a Termux shell.

Answer 2

Per the comment by Irfan Latif above, the following works:

1. Launch termux

2. Do the following:

   echo 'sv up sshd
   sshd started' > .profile
   

3. Run this whenever I want to start sshd via adb:

   adb shell am start -n com.termux/.HomeActivity
   

Answer 3

adb shell am start -n com.termux/.HomeActivity
adb shell input text "your command here"
adb shell input keyevent ENTER

Answer 4

2024 proper solution

Termux allows you to start the run command service through am allowing you to pass extras as well

adb shell /system/bin/am startservice --user 0 -n com.termux/com.termux.app.RunCommandService \
-a com.termux.RUN_COMMAND \
--es com.termux.RUN_COMMAND_PATH '/data/data/com.termux/files/usr/bin/sleep' \
--esa com.termux.RUN_COMMAND_ARGUMENTS '10' \
--es com.termux.RUN_COMMAND_WORKDIR '/data/data/com.termux/files/home' \
--ez com.termux.RUN_COMMAND_BACKGROUND 'true' \
--es com.termux.RUN_COMMAND_SESSION_ACTION '0'

In this command notice how I set the background option to true which is important so that it automatically runs in the background(the notification will show you that a task is being run in the background)

In the example above, we are executing the sleep command and passing in 10 as an argument which will make termux basically execute sleep 10 Once the execution is completed, termux will automatically exit
