s3go is a simple Golang port of the AWS S3 CLI. It was built as a Hack Week project with the primary objective being to learn some basic features of Go.
The CLI aims to use the concurrency features of Golang to improve performance for simple S3 tasks, such as copying files or restoring files from Glacier.
$ go get -u github.com/scruwys/s3go
$ s3go --help

Use "s3go [command] --help" for more information about a command.
Every command has been implemented except for sync. Intial benchmarks show that most do not perform better than the existing awscli tool. More on that soon.
The primary difference is the addition of the --concurrency flag, which allows you to control how many goroutines are spun up to handle command executation:
s3go rm s3://my-test-bucket/20200101/tmp/ --recursive --concurrency 5
