-f --file

-f filename or --file filename uses filename as the source of commands instead of reading commands interactively. After the file is processed, vsql terminates.

If filename is a hyphen (-), standard input is read.

Using this option is different from writing vsql < filename. Using -f enables some additional features such as error messages with line numbers. Conversely, the variant using the shell's input redirection should always yield exactly the same output that you would have gotten had you entered everything manually.
