Error on running Marcus scripts

thanks marcus for quick reply
regarding my problem on burning the latest uhd images (003-002-003) for
n210, i
received the massage “FPGA build of the device is incompatible with the
code build”.
Marcus replied that i should update the host side and said:

If you’re on Ubuntu or Fedora Linux, the easiest is to fetch:

And run it. It will download and build the latest Gnu Radio and UHD

i ran the script through the aforementioned address on the terminal by
fallowing command
i received the fallowing error message: 52: function: not found
[: 73: -gt: unexpected operator 90: Syntax error: “}” unexpected

what is my mistake and going wrong
thank you all
