Tasker to programmatically uninstall apps

Question

I would like to setup a tasker profile to check every predetermined time for any apps not on my approved list (BaselineApps.txt) and uninstall them.
I am a noob to shell scripting and tasker.
This is what I got so far, it might not be the most efficient way to do it.




  • I run the following command via Termux Task plugin.




    
pm list packages >/storage/emulated/0/Apps.txt
    
diff --unchanged-line-format= --old-line-format= --new-line-format='%L' /storage/emulated/0/BaselineApps.txt /storage/emulated/0/Apps.txt | sed 's/^[^:]*://' >/storage/emulated/0/NewApps.txt

  • Read file NewApps.txt to variable %Apps


  • ArraySet %Apps value %Apps


  • For each %eachapp in %Apps()


  • Run Shell pm uninstall %eachapp

  • End for



For the most part it works, except it errors out sometimes. Can someone help me?

Answer

So I figured out my issue. I had upgraded to Android Nougat. Pm list packages is obsolete. The proper command is pm cmd package list packages.



Here is my setup:




 Diff


 A1: Run Shell [ Command:cmd package list packages Timeout (Seconds):0 Use Root:On Store Output In:%tempapps Store Errors In: Store Result In: ] 


 A2: Write File [ File:Apps.txt Text:%tempapps Append:Off Add Newline:Off ] 


 A3: Termux [ Configuration:Execute ~/.termux/tasker/DiffApps.txt  Timeout (Seconds):0 ] 


 A4: Wait [ MS:250 Seconds:0 Minutes:0 Hours:0 Days:0 ] 


 A5: Read File [ File:NewApps.txt To Var:%Apps ] 


 A6: Array Set [ Variable Array:%Apps Values:%Apps Splitter: ] 


 A7: For [ Variable:%eachapp Items:%Apps() ] 


 A8: Flash [ Text:%eachapp Long:On ] 


 A9: Run Shell [ Command:pm uninstall %eachapp Timeout (Seconds):0 Use Root:On Store Output In: Store Errors In: Store Result In: ] 


 A10: End For 


 A11: Variable Clear [ Name:apps* Pattern Matching:On Local Variables Only:Off ]
