the correct syntax

The reason for the error Command 'rf' not found is because you have accidentally added a space character between rf and kill

The correct syntax is rfkill command

where command is one of:

    help
    event
    list [IDENTIFIER]
    block IDENTIFIER
    unblock IDENTIFIER
where IDENTIFIER is the index no. of an rfkill switch or one of:
     all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm

Since you appear to be trying to unblock a particular device the syntax would be:

rfkill unblock all

You should note - rfkill unblock all will only release the device lock that has been created by the operating system - i.e. a soft-block.

If your device has been locked by a physical device - for example, physical switch, keyboard lock such as Fn+Function-key then the rfkill unblock all will not work - this is a so called hard-block

You can see the status of devices with rfkill list all - example results are:

rfkill list all
0: acer-wireless: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
