## What it is
s5cmd is a very fast parallel command-line tool for executing S3 and local filesystem operations such as upload, download, copy, move, and delete at high throughput. It supports wildcards, batch command files, S3-compatible services like Google Cloud Storage, and significantly outperforms aws-cli and s3cmd.

## Use cases
- transfer large numbers of files to and from s3 at maximum speed
- bulk upload or download objects from s3 from the command line
- saturate a high-bandwidth link when moving data to object storage
- batch copy and delete s3 objects with wildcards
- run s3 operations against s3-compatible storage like google cloud storage
- replace aws cli s3 commands with a much faster alternative

## When to choose
- you need maximum throughput for bulk S3 transfers
- you work with very large numbers of objects and want wildcard and batch support
- you use S3-compatible object storage services beyond AWS

## When to avoid
- you need a full-featured AWS CLI for non-storage services
- you prefer a GUI or interactive sync tool like rclone's mounting features
