How can I tell how many objects I've stored in an S3 bucket?

Question

Unless I\'m missing something, it seems that none of the APIs I\'ve looked at will tell you how many objects are in an /. Is ther

Answer 1

There is an easy solution with the S3 API now (available in the AWS cli):

aws s3api list-objects --bucket BUCKETNAME --output json --query "[length(Contents[])]"

or for a specific folder:

aws s3api list-objects --bucket BUCKETNAME --prefix "folder/subfolder/" --output json --query "[length(Contents[])]"

Answer 2

In s3cmd, simply run the following command (on a Ubuntu system):

s3cmd ls -r s3://mybucket | wc -l

Answer 3

You can easily get the total count and the history if you go to the s3 console "Management" tab and then click on "Metrics"... Screen shot of the tab

Answer 4

You can just execute this cli command to get the total file count in the bucket or a specific folder

Scan whole bucket

aws s3api list-objects-v2 --bucket testbucket | grep "Key" | wc -l
aws s3api list-objects-v2 --bucket BUCKET_NAME | grep "Key" | wc -l

you can use this command to get in details

aws s3api list-objects-v2 --bucket BUCKET_NAME

Scan a specific folder

aws s3api list-objects-v2 --bucket testbucket --prefix testfolder --start-after testfolder/ | grep "Key" | wc -l

aws s3api list-objects-v2 --bucket BUCKET_NAME --prefix FOLDER_NAME --start-after FOLDER_NAME/ | grep "Key" | wc -l

Go to AWS Billing, then reports, then AWS Usage reports. Select Amazon Simple Storage Service, then Operation StandardStorage. Then you can download a CSV file that includes a UsageType of StorageObjectCount that lists the item count for each bucket.
