How can I use adb to uninstall all 3rd party user apps?

I am trying to create a script that will retrieve and uninstall all user apps in one batch operation through adb. Does anyone know how I would be able to do this?

I can currently list out all 3rd party apps through

adb shell pm list packages -3

Could I somehow direct the list of packages this generates into an uninstall command in adb?

Solution

Try:

adb shell pm list packages -3 | cut -d':' -f2 | tr '\r' ' ' | xargs -r -n1 -t adb uninstall

First part is to get 3rd party app package names
second part is to split package names using delimiter :
third part is to replace carriage return with space (sometimes it would be a problem in linux machines. Try removing this part and check if you face it)
and the last one is for uninstalling one by one
- r option will prevent xargs from running the command if there are no third party apps installed
- n1 option is to pass one result value as argument at a time to the command
- t is for printing the command being executed)

Hope it helps!!!
