You will get an error as below when running the command:

./msdat.py oleautomation -s x.x.x.x -p 1433 -U sa -P sa --put-file '/home/kali/Desktop/test.txt' 'C:/temp/' 


[1] (x.x.x.x:1433): Try to copy the local file /home/kali/test.txt to C:/temp/

AttributeError: 'bytes' object has no attribute 'encode'. Did you mean: 'decode'?

The change here should resolve it.
