The command sup ${filename-html} appears to be using a variable called filename-html in a script or programming language that supports variable interpolation or substitution.

By using sup, it suggests that the command might perform some action or operation on the value stored in filename-html, but without more context or information about the specific programming language or script, it is difficult to determine the exact purpose or outcome of this command.
