Shell approach without external utilities..
Code:
file=capturesummary.txt
# use a code block to direct the input file into the two consecutive while loops.
{ 
  # while read dev, read the first part
  while read dev
  do
    # if $dev starts with "RP"
    case $dev in
      RP*)
        # cut the trailing hash-sign
        dev=${dev%#} 
        # print the device name and cut the text upto and including the colon'
        printf "Device Name:  %s\n\n" "${dev#*:}"
        # break the for loop so we can start the next loop
        break
    esac
  done

  # read these 5 variables
  while read interface total up down admindown
  do
    # if $interface equals one of the values below
    case $interface in
      IFT_ETHERBUNDLE|IFT_GETHERNET|IFT_TENGETHERNET) 
        # print the port type
        printf 'Port type:\t %s :\n' "$interface"
        # and print the $total followed by the sum of $up and $down, and then $admindown
        printf '%3d\t%s\n' "$total" Capacity "$((up+down))" "Ports in Use" "$admindown" "Ports Not in Use"
    esac
  done
# feed "$file" into the code block
} < "$file"

fdformat

FDFORMAT(8)						     Linux Programmer's Manual						       FDFORMAT(8)

NAME

       fdformat - Low-level formats a floppy disk

SYNOPSIS

       fdformat [-n] device

DESCRIPTION

       fdformat  does  a  low  level  format on a floppy disk.	device is usually one of the following (for floppy devices, the major = 2, and the
       minor is shown for informational purposes only):

	      /dev/fd0d360  (minor = 4)
	      /dev/fd0h1200 (minor = 8)
	      /dev/fd0D360  (minor = 12)
	      /dev/fd0H360  (minor = 12)
	      /dev/fd0D720  (minor = 16)
	      /dev/fd0H720  (minor = 16)
	      /dev/fd0h360  (minor = 20)
	      /dev/fd0h720  (minor = 24)
	      /dev/fd0H1440 (minor = 28)

	      /dev/fd1d360  (minor = 5)
	      /dev/fd1h1200 (minor = 9)
	      /dev/fd1D360  (minor = 13)
	      /dev/fd1H360  (minor = 13)
	      /dev/fd1D720  (minor = 17)
	      /dev/fd1H720  (minor = 17)
	      /dev/fd1h360  (minor = 21)
	      /dev/fd1h720  (minor = 25)
	      /dev/fd1H1440 (minor = 29)

       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
       mat has not been autodetected earlier.  In this case, use setfdprm(8) to load the disk parameters.

OPTIONS

       -n     No verify.  This option will disable the verification that is performed after the format.

SEE ALSO

       fd(4), setfdprm(8), mkfs(8), emkfs(8)

       Werner Almesberger (almesber@nessie.cs.id.ethz.ch)

AVAILABILITY

       The fdformat command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
