every time i open cmd i encounter bash script how can i close it

exit
or in a string like : bash: /opt/ros/noetic/setup.bash && exit
If you're opening just one file, you don't really need to use a script, because a script is meant to be an easy way to run multiple commands in a row, while here you just need to run two commands (including exit).

Yalnızca bir dosya açıyorsanız, bir komut dosyası kullanmanıza gerçekten gerek yoktur, çünkü bir komut dosyası, arka arkaya birden fazla komut çalıştırmanın kolay bir yolu olması gerekirken, burada yalnızca iki komut çalıştırmanız gerekir ).
