I am migrating my data from Amazon-S3 to Google-Cloud Storage. I have copied my data using gsutil:
$ gsutil cp -R s3://my_bucket/* gs://my_bucket
What I want to do next is to check if all the files in S3 is properly exist in Google Storage.
At the moment all I did is to do print file list in file and then do simple Unix diff but that doesn't really check the file integrity.
What's the good way to check that?
