[Discuss-gnuradio] error on running Marcus scripts

[ahmad]

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 host
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:

http://www.sbrac.org/files/build-gnuradio

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 the
fallowing command
sh script_marcus.sh
i received the fallowing error message:
script_marcus.sh: 52: function: not found
[: 73: -gt: unexpected operator
script_marcus.sh: 90: Syntax error: "}" unexpected

what is my mistake and going wrong
thank you all
