How to get the file diff between two S3 buckets?

问题:

So I have an S3 bucket of videos (several hundred), upon which I used ElasticTranscoder to transcode everything into a second, optimised bucket.

However, when I inspect my second bucket, there are 40-50 less objects, but I cannot figure out what they are (the directory structure is deeply nested etc).

How can I get the file diff of two buckets using aws s3api list-objects?

Perhaps there are files in the bucket which are not videos, which I somehow didn't know about.

回答1:

Using Display only filenames:

aws s3 ls s3://bucket-1 --recursive | awk '{$1=$2=$3=""; print $0}' | sed 's/^[ \t]*//' | sort > bucket_1_files aws s3 ls s3://bucket-2 --recursive | awk '{$1=$2=$3=""; print $0}' | sed 's/^[ \t]*//' | sort > bucket_2_files  diff bucket_1_files bucket_2_files
