    It was introduced in bash-3.0-alpha; I have never used it (or any
    form of [[...]]).

    I always compile and install the latest bash; too many distros
    either have old versions and/or disable various features. The last
    time I tried a Debian default bash, my mail scripts stopped
    working: they had removed socket file descriptors. Mandrake
    disables the time built-in.
