QUOTA
quota accepts human-readable case-insensitive number
suffixes such as "k", "m", "g" and "t" referring to the metric units KB,
MB, GB and TB respectively. Adding an "i" to these prefixes, uses the IEC
units, so that "gi" refers to "gibibyte" or "GiB". A "b" at the end is
also accepted. Without suffixes the unit is bytes.
FLAGS:
{{range .VisibleFlags}}{{.}}
{{end}}
EXAMPLES:
1. Set hard quota of 1gb for a bucket "mybucket" on MinIO.
{{.Prompt}} {{.HelpName}} myminio/mybucket --size 1GB
