single binary curl download cannot handle file overwrite

[jovezhong]

Describe what's wrong

curl -sSf https://raw.githubusercontent.com/timeplus-io/proton/develop/install.sh | sh

is the quick way to install proton.
But if I have downloaded this once, next time I ran this command, it will show file exists but without waiting for y/n to overwrite, it just download the file and create the 2nd file without overwriting the previous proton binary

curl -sSf https://raw.githubusercontent.com/timeplus-io/proton/develop/install.sh | sh
-n 'proton' file exists. Do you want to overwrite it? (y/n):
