          NAME
               xtd - extract and print xt driver link structure

          SYNOPSIS
               xtd [-f] [-n ...]

          DESCRIPTION
               The xtd command is a debugging tool for the xt(7) driver.
               It performs an XTIOCDATA ioctl(2) call on its standard input
               file to extract the Link data structure for the attached
               group of channels.  This call will fail if data extraction
               has not been configured in the driver or the standard input
               is not attached to an xt(7) channel.  The data are printed
               one item per line on the standard output.  The output should
               probably be formatted via pr -3.

               The optional flags affect output as follows:

                 -n      n is a number in the range 0 to 7.  Channel n is
                         included in the list of channels to be printed.
                         The default prints all channels, whereas the
                         occurrence of one or more channel numbers implies
                         a subset.

                 -f      Causes a ``formfeed'' character to be put out at
                         the end of the output for the benefit of page-
                         display programs.

          EXIT STATUS
               Returns 0 upon successful completion; 1 otherwise.
