## Usage

Start MinIO in a distributed setup, with 'ftp/sftp' enabled.

```
minio server http://server{1...4}/disk{1...4}
   --ftp="address=:8021" --ftp="passive-port-range=30000-40000" \
   --sftp="address=:8022" --sftp="ssh-private-key=/home/miniouser/.ssh/id_rsa"
...
...
```

Following example shows connecting via ftp client using `minioadmin` credentials, and list a bucket named `runner`:

```
ftp localhost -P 8021

	checkLinkOutput("0x0", "-B argument must have even number of digits")
	checkLinkOutput("0x00", "usage")
	checkLinkOutput("0xYZ", "-B argument contains invalid hex digit")
	checkLinkOutput("0x"+strings.Repeat("00", 32), "usage")
	checkLinkOutput("0x"+strings.Repeat("00", 33), "-B option too long (max 32 digits)")
}

func checkLinkOutput(buildid string, message string) {
	cmd := exec.Command("go", "tool", "link", "-B", buildid)

		if err != nil {
			fmt.Fprintln(os.Stderr, err)
			os.Exit(1)
		}
	}

	uid, err := strconv.ParseUint(u.Uid, 10, 32)
	if err != nil {
		fmt.Fprintf(os.Stderr, "invalid UID: %v\n", err)
		os.Exit(1)
	}
	gid, err := strconv.ParseUint(u.Gid, 10, 32)
	if err != nil {
		fmt.Fprintf(os.Stderr, "invalid GID: %v\n", err)
		os.Exit(1)
	}

	cmd := exec.Command(os.Args[0])

// but if the size argument specifies a narrower width the result can be
// converted to that narrower type without data loss:
//
//	s := "2147483647" // biggest int32
//	i64, err := strconv.ParseInt(s, 10, 32)
//	...
//	i := int32(i64)
//
// [FormatBool], [FormatFloat], [FormatInt], and [FormatUint] convert values to strings:
//
//	s := strconv.FormatBool(true)
//	s := strconv.FormatFloat(3.1415, 'E', -1, 64)
