-h@help (shows this usage information) (mnemonic: 'h'elp)
-p printf_format@use this printf format for IP address and hostname, respectively.  The default format is '%.0s%s', which supresses the printing of the IP address (i.e. "%.0s" specifies printing a string with a maximum width of zero).  To maintain column widths (since both the IP address and hostname vary in lenght), a format like this may be useful: '%-16.16s %-20s' (mnemonic: 'p'rintf format)
-i extension@edit the files in place (rather than sending to standard output) This option requires file name(s) argument(s).  The extension is added to the name of the old file to make a backup copy.  If you don't wish to make a backup, use "-I".  (mnemonic: edit 'i'n place)
-I@like "-i" but no backup is made.  (mnemonic: edit 'I'n place, trusting this script 'I'mplicitly. ;^)
