Maybe, it is because SFTP protocol doesn't specify what ~ represents. But it works when I uploaded a file using "./curl -v -u qxu:fair123 -T CMakeLists.txt sftp://", as Guenter suggested.

Kind of strange here.

Just want to say thank you very much for your help all along. You are patient and nice.
