A simple static binary that outputs the contents of a given S3 Bucket and key prefix.
This is a sad tool with an expected audience of 1 user, me. I was unable to successfully execute awscli commands using the Golang ssh.Session.CombinedOutput function. Output was hidden; mysterious error messages were returned and I was generally confused. After a few hours of unsuccessfully debugging this, I spent 15 minutes to write this statically compilable tool that does exactly what I need with no dependencies!
s3ls <region> s3://<bucket-name>/<prefix>/
This will return the names of all objects stored at s3://<bucket-name>/<prefix>/.
