Tasker: Using Termux to manage application states with Rish ADB

This article demonstrates how to use Termux in combination with Tasker and Rish to manage application states; this allows users to enable or disable built-in applications directly from the device (when configured).

If you haven’t already configured Shizuku (Rish) with Termux there is a guide available at: Termux, Shizuku and Rish configuration for Android 14

Rish variants for ADB commands

Note the following table assume that you have installed Rish within Termux at path: /data/data/com.termux/files/usr/bin/rish_auto if you have installed Rish with a different Shell or path ensure you update it here.

Description	Command	Rish Equivalent
List all packages	adb shell pm list packages	rish_auto pm list packages
List disabled packages	This command lists all disabled packages. adb shell pm list packages -d	rish_auto pm list packages -d
List enabled packages	adb shell pm list packages -e	rish_auto pm list packages -e
Disable packages	adb shell pm disable-user --user 0 <package_to_disable>	rish_auto pm disable-user --user 0 <package_to_disable>
Enable packages	Find the package name that corresponds to the app you want to enable.  adb shell pm enable <package_to_enable>	rish_auto pm enable <package_to_enable>
Uninstall packages	Note that this on uninstall applications from user_mode: adb shell pm uninstall -k --user 0 <package_to_disable>	rish_auto pm uninstall -k --user 0 <package_to_disable>
Reinstall built-packages to userspace	adb shell cmd package install-existing <name of package>	rish_auto cmd package install-existing <name of package>
