Run termux script using macrodroid

Running a Termux script from MacroDroid is best done using the Termux:Tasker plugin. Despite the name, this plugin works perfectly with MacroDroid.

Prerequisite: The "F-Droid" Rule

Critical: You must install both Termux and the Termux:Tasker plugin from F-Droid.

• If you installed Termux from the Google Play Store, it will not work because the Play Store version is outdated.
• Action: Uninstall the Play Store version and install the latest versions from F-Droid.

Step 1: Set up the Termux Environment

1. Open Termux.
2. Create the mandatory folder for external scripts:

   mkdir -p ~/.termux/tasker

3. Move your script to this folder (or create a new one there).
   • Example: nano ~/.termux/tasker/myscript.sh
4. Important: Make the script executable.

   chmod +x ~/.termux/tasker/myscript.sh

5. Ensure your script has the correct shebang:
   • Bash: #!/data/data/com.termux/files/usr/bin/bash
   • Python: #!/data/data/com.termux/files/usr/bin/python

Step 2: Grant Permissions

Android requires you to explicitly allow MacroDroid to run commands in Termux.

1. Go to Android Settings → Apps → MacroDroid.
2. Open Permissions.
3. Allow: "Run commands in Termux environment".

Step 3: Create the MacroDroid Action

1. Create a new Macro.
2. Add a Trigger (e.g., Widget, Shake device, Time of day).
3. Add an Action:
   • Applications → Tasker/Locale Plugin
   • Select Termux:Tasker
   • Tap again to configure
4. In the Termux:Tasker configuration:
   • Executable: Select your script from ~/.termux/tasker.
   • Arguments: Add arguments (optional).
   • In Terminal: Check to view terminal output; uncheck to run silently.
5. Save and test the macro.

Troubleshooting

Issue	Solution
"Permission Denied"	You likely forgot chmod +x filename.sh.
"File not found"	Ensure the script is inside ~/.termux/tasker/.
Script runs but fails	Fix the shebang using: termux-fix-shebang filename.sh.
Plugin List is Empty	Restart MacroDroid & Termux. Verify the folder exists.
