I'm beginner in working openwifi/sdr

Im facing an error stating as below while running ./wgh.sh. Could you guide in working out this project
Below is the issue:

root@analog:~/openwifi# ./wgd.sh
usage:
Script for load (or download+load) different driver and FPGA img without rebooting
no argument: Load .ko driver files and FPGA img (if system_top.bit.bin exist) in current dir with test_mode=0.
1st argument: If it is a NUMBER, it will be assigned to test_mode. Then load everything from current dir.
1st argument: If it is a string called "remote", it will download driver/FPGA and load everything.

• 2nd argument (if exist) is the target directory name for downloading and reloading
• 3rd argument (if exist) is the value for test_mode
  1st argument: neither NUMBER nor "remote" nor a .tar.gz file, it is regarded as a directory and load everything from it.
• 2nd argument (if exist) is the value for test_mode
  1st argument: a .tar.gz file, it will be unpacked then load from that unpacked directory
• 2nd argument (if exist) is the value for test_mode
