I have tried to run these commands:
aws s3api list-objects --bucket bucket --profile key --output json --query "[length(Contents[])]"
and
aws s3 --profile=key ls s3://bucket/ --recursive --summarize
but what I'm curious about is that some of the objects have been marked for deletion. Do these commands count the objects marked for deletion or are they excluded?
commands shared here will list objects/files given in a specified path. these commands will not display any of the deleted objects. for details refer S3 ls

We want to find out files uploaded/creation date of oldest object present in AWS S3 bucket.
Could you please suggest how we can get it.
You can use the AWS Command-Line Interface (CLI) to list objects sorted by a field:
aws s3api list-objects --bucket MY-BUCKET --query 'sort_by(Contents, &LastModified)[0].[Key,LastModified]' --output text
This gives an output like:
foo.txt 2021-08-17T21:53:46+00:00

I'm trying to list the 'folders' in a S3 bucket under a given prefix.
aws --profile my-profile s3api list-objects-v2 --bucket my-bucket --prefix releases/com/example/app/ --delimiter / --query 'CommonPrefixes[*].Prefix'
There are dozens of folders under the prefix, each containing many files, I I should be able to list the folders., i.e. they do exist
There is no CommonPrefixes returned by this query, so I get null as an output. What am I doing wrong?
running aws-cli/2.0.0 Python/3.7.5 Windows/10 botocore/2.0.0dev4 in Git Bash terminal on Windows.
I am using a command using aws cli in my windows machine to get latest file from s3 bucket .
aws s3 ls s3://Bucket-name --recursive | sort |tail -n 1
It is listing all the files in sorted manner according to date upto here:
aws s3 ls s3://Bucket-name --recursive | sort
But writing the full command throws error:
'Tail is not recognized as an internal or external command'.
Is there some other alternative for tail or for the full command.
The AWS CLI permits JMESPath expressions in the --query parameter.
This command shows the most recently-updated object:
aws s3api list-objects --bucket my-bucket --query 'sort_by(Contents, &LastModified)[-1].Key' --output text
It's basically saying:
Sort by LastModified
Obtain the last [-1] entry
Show the Key (filename)
I want to get list of all files in S3 bucket with particular naming pattern.
For Eg if i have files like
aaaa2018-05-01
aaaa2018-05-23
aaaa2018-06-30
aaaa2018-06-21
I need to get list of all files for 5th month.Output should look like:
aaaa2018-05-01
aaaa2018-05-23
I executed the following command and the result was empty:
aws s3api list-objects --bucket bucketname --query "Contents[?contains(Key, 'aaaa2018-05-*')]" > s3list05.txt
when i check the s3list05.txt its empty. Also i tried the below command and
aws s3 ls s3:bucketname --recursive | grep aaaa2018-05* > s3list05.txt
this command lists me all the objects present in the file.
Kindly let me know the exact command to get desired output.
You are almost there. Try this:
aws s3 ls s3://bucketname --recursive | grep aaaa2018-05
or
aws s3 ls bucketname --recursive | grep aaaa2018-05
The Contains parameter doesn't need a wildcard:
aws s3api list-objects --bucket bucketname --query "Contents[?contains(Key, 'aaaa2018-05')].[Key]" --output text
This provides a list of Keys.
--output text removes the JSON formatting.
Using [Key] instead of just Key puts them all on one line.
I must move into another bucket only files changed in the year 2015. How can I write this condition?
aws s3 mv <condition??> s3://bucket1 s3://bucket2 --recursive
I don't think you can directly do that through through the s3 option.
what you can do though is a 2 steps approach:
get the list of files that have been modified after a date
aws s3api list-objects --bucket bucket1" --query 'Contents[?LastModified > `2015-01-01`].[Key]' --output text
Based on this list you can move the items.
I have not tried and not an shell expert but something around this
aws s3api list-objects --bucket "<YOUR_BUCKET>" --query 'Contents[?LastModified > `2015-01-01`].[Key]' --output text | xargs aws s3 mv s3://bucket2/ -
