# Dup

 [![Build Status](https://travis-ci.org/segmentio/go-dup.svg?branch=master)](https://travis-ci.org/segmentio/go-dup)

 `Dup(fd, name)` returns a RW pipe for the given `fd`. For example

 this allows you to proxy stdio, logging to your preferred logger

 and then re-write to the original stdio stream.

## Example

```go

r, w, err := Dup(1, "stdout")

check(err)

go func() {

  fmt.Printf("testing\n")

}()

buf := bufio.NewReader(r)

line, err := buf.ReadString('\n')

check(err)

fmt.Fprintf(w, line)

```
