How to use YAFUFlash in linux

I am trying to update my Supermicro BMC firmware using Yafuflash. I unzipped the file. Inside there was the firmware image and a folder with a Linux zip, where the Yafuflash file was located. I unzipped that and copied the image into it. In the Readme.txt it says to copy libipmi.so.1 to /lib and pass the command ldconfig. After doing so I need to pass the command :

Yafuflash -cd -full -force-boot B8DTT130.ima

But it says no such command Yafuflash.

Also when I typesudo./Yafuflash

it says unable to find file or directory.(I am in the folder where Yafuflash is located)

So yea my question is how do I get the Yafuflash command to work so I can update my firmware. I am using Ubuntu Server 20.04
