You can remove AppScope by simply deleting the binary, along with the rest of the contents of the SCOPE_HOME directory. For example, if your SCOPE_HOME directory is /opt/appscope/:
rm -rf /opt/appscope/
Then delete the associated history directory:
cd ~
rm -rf .scope/
Currently scope’d applications will continue to run. To remove the AppScope library from a running process, use scope detach <process_ID>.
