title: Using grep to remove specific objects in GCS with gsutil -rm
body: <p>I have a bucket with many objects, and I can successfully use grep to take the specific objects and output them into a text file. I want to use gsutil -rm and read the text file line by line and remove the corresponding object in gcs, but how can I go about doing this? </p>
  
  <p>Or is there a way to directly remove objects from GCS using gsutil -rm and grep? Thanks!</p>
