aws-s3-ls

List all S3 buckets in your account

$ aws s3 ls

$ aws s3 ls s3://[bucket-name]/

$ aws s3 ls s3://[bucket-name]/[prefix/]

$ aws s3 ls s3://[bucket-name] --recursive

$ aws s3 ls s3://[bucket-name] --recursive --human-readable --summarize

$ aws s3 ls --bucket-name-prefix [my-prefix]

aws s3 ls [S3Uri] [options]

aws s3 ls lists S3 objects and common prefixes under a specified prefix, or lists all S3 buckets when no URI is provided. The output shows the last modified date, size, and object key for each item.
When listing bucket contents, objects are displayed with timestamps and sizes, while common prefixes (similar to directories) are shown with a PRE indicator. The command supports recursive listing to show all objects under a prefix.

--recursive

List all objects under the specified prefix, including nested objects

Display file sizes in human-readable format (KB, MB, GB)

Display summary information including total number of objects and total size

Number of results to return in each response (default: 1000)

Confirm that the requester will pay for request and data transfer costs

Filter bucket list to names beginning with the specified prefix

Filter bucket list to buckets in the specified AWS Region

The --output and --no-paginate global arguments are ignored for this command. Output format is fixed and cannot be changed to JSON or other formats. For programmatic access to S3 listings with flexible output, use aws s3api list-objects-v2 instead.
