Auto answer "Terminate batch job (Y/N)" message on windows terminal

the message is very annoying but can be handled using clink.
install clink and open file C:\Users\<username>\AppData\Local\clink\settings and set property terminate_autoanswer to 1

# name: Auto-answer terminate prompt
# type: enum
# Automatically answers cmd.exe's 'Terminate batch job (Y/N)?' prompts. 0 =
# disabled, 1 = answer 'Y', 2 = answer 'N'.
terminate_autoanswer = 1
