$ drive push -h
Usage of drive push:
  -hidden=false: allows syncing of hidden paths
  -no-prompt=false: shows no prompt before applying the push action
  -r=true: performs the push action recursively

The command does not mention moving all existing files to the 'trash' directory in google drive. Thank god my old files were moved to trash instead of permanent deletion.

The result fater this was only the directory that i push'ed -r . The expectred result is the additive effect of the directory I pushed recursively + old files.
