About:
S5cmd is a high-performance command-line interface for managing data on Amazon S3 and local filesystems. It leverages parallel processing to deliver significantly faster operations compared to standard tools like the AWS CLI. The tool supports a wide range of S3 operations, including cp, mv, ls, rm, and sync, with features like automatic retries and bandwidth throttling.

Key Features:

Parallel execution for high throughput
S3 and local filesystem operations
Automatic retries and error handling
Bandwidth throttling support
S3 Select and lifecycle management

Use Cases:

High-speed bulk data transfers to and from S3
Automated backup and synchronization scripts
Large-scale data processing pipelines
Managing S3 buckets via intuitive commands

Alternatives:

aws-cli s3 – AWS CLI is more ubiquitous but significantly slower for bulk operations.
rclone – Rclone supports many more cloud providers but is written in Go and has a different command structure.
s3cmd – S3cmd is a Python-based tool that is older and generally slower than S5cmd.
