Basically, tar -vvxf produces the same format output as tar -tvf. If we are going to document the long format, how about something like: .It Fl v Verbose operation mode. In list mode, or if .Fl v is specified multiple times, .Nm will use a long format for listing files, similar to .Xr ls 1 .Fl l . Or perhaps: .It Fl v Verbose operation mode. If .Fl v is specified multiple times or if the .Fl t option is also specified, .Nm will use a long format for listing files, similar to .Xr ls 1 .Fl l . - todd
