- This option tells the --remote-name option to use the server-specified
- Content-Disposition filename instead of extracting a filename from the URL. If
- the server-provided file name contains a path, that will be stripped off
- before the file name is used.
- The file is saved in the current directory, or in the directory specified with
- --output-dir.
- If the server specifies a file name and a file with that name already exists
- in the destination directory, it will not be overwritten and an error will
- occur. If the server does not specify a file name then this option has no
- effect.
- There's no attempt to decode %-sequences (yet) in the provided file name, so
- this option may provide you with rather unexpected file names.
- **WARNING**: Exercise judicious use of this option, especially on Windows. A
- rogue server could send you the name of a DLL or other file that could be
- loaded automatically by Windows or some third party software.
