    Please explain why this bash string function fails

    Ubuntu 12.04.1 LTS
    GNU bash, version 4.2.24(1)-release (x86_64-pc-linux-gnu)


    I'm looking to replace '/' with '-'

    why is output 11-/11-/2012 and not 11-11-2012?


    #!/bin/bash
    a=11/11/2012
    b=${a//\//-/}
    echo $a $b
    exit

    OUTPUT:
    11/11/2012 11-/11-/2012
