ls

To list the content of a bucket:

s3m ls <s3 provider>/<bucket>

TIP

If using Cloudflare R2 you need to pass the prefix (option -p, --prefix), for example:

s3m ls <r2>/<bucket>/ -p "test"

To list available buckets:

s3m ls <s3 provider>

To list in-progress multipart uploads:

s3m ls <s3 provider>/<bucket> -m
