}
function print_average() {
        printf("\nTotal Sum of %s site is: %d Mbps\n ", last, average)
}

last != substr($1, 1, 7) {
        if(NR > 1) {
                print_total()
                printf("\n=======================\n")
        }
        last = substr($1, 1, 7)
        total = 0
        average = 0
}
{       print
        total += $2
        average total/NR
}
END {   print_total()
        print_average()
}' hhhh > datarate.log

sum

sum(n)									sum								    sum(n)

NAME

       sum - calculate a sum(1) compatible checksum

SYNOPSIS

       package require Tcl 8.2

       package require sum ?1.0?

       ::crc::sum ?-format format? message

       ::crc::sum ?-format format? -filename file

DESCRIPTION

       This  package  provides	a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data.  The
       BSD sum algorithm is used by default but the SysV algorithm is also available.

COMMANDS

       ::crc::sum ?-format format? message

       ::crc::sum ?-format format? -filename file
	      The command takes string data or a file name and returns a checksum value calculated using the sum(1) algorithm. The result is  for-
	      matted using the format(n) specifier provided or as an unsigned integer (%u) by default.

OPTIONS

       -filename name
	      Return a checksum for the file contents instead of for parameter data.

       -format string
	      Return the checksum using an alternative format template.

EXAMPLES

       % crc::sum "Hello, World!"
       37287

       % crc::sum -format 0x%X "Hello, World!"
       0x91A7

       % crc::sum -file sum.tcl
       13392
