Listing Sizes in AWS S3 Buckets
Listing sizes in AWS S3 Buckets
Getting the whole bucket size
aws s3 ls s3://$BUCKETNAME/ --recursive --human-readable --summarize | tail -n2
Tail is used because otherwise all files will be printed on screen (but you may want that for some reason).
Getting the size of a specific directory/file
You just need to add the path to the bucket name:
aws s3 ls s3://$BUCKETNAME/some/dir --recursive --human-readable --summarize | tail -n2
Getting the size of all subdirs
If you imagine there is something like ncdu or du -ha -d 1 /foo/bar you’re wrong. If you want to get the size of all subdirs you have to do it yourself:
Your Bucket contains in $BUCKETNAME/some/dir multiple subdirs (for e.g. 2020, 2019 and 2018) and you want to see the size of these 3 directories.
S3PATH='s3://$BUCKETNAME/some/dir/'
for dir in $(aws s3 ls "${S3PATH}" | grep PRE | awk '{print $2}'); do
echo "${S3PATH}${dir}:"
aws s3 ls "${S3PATH}${dir}" --recursive \
--human-readable \
--summarize\
| tail -n2
done
A | column after done could improve the readability.
