Usage:

ifdo -t time -i iface -r [ERROR | SINACTIVE | SACTIVE] command

    -t time:        wait up to time seconds before exiting
    -i interface:   peform operation on this interface
    -r requirement: test requirement
                    ERROR     - as found in man errno eg. ENXIO
                    SINACTIVE - no carrier
                    SACTIVE   - associated/active
    command:        command to execute when requirement is valid

Eg:

ifdo -t 30 -i wi0 -r SACTIVE '/sbin/dhclient wi0'
                                                
    wait for up to 30 seconds for interface wi0 to become active
    then run dhclient when it does. This allows an interface
    to associate with AP before running dhclient.

ifdo -t 30 -i wi0 -r ENXIO '/sbin/reboot'

    wait for up to 30 seconds for interface wi0 to exist, if not
    reboot. (although an uncommon requirement, this can be
    useful if an interface doesn't attach properly when booting,
    which has occured in my experience with one pccard bridge
    with a wi device plugged in).
