In windows

start -> run -> cmd -> goto the fps.csv folder

type the entire line as given below and press enter

Code:
perl -e "my $total=0; while (<>) { chomp; my $value = (split /([,:])/)[2]; $total=$value+$total; }print $total/$." fps.csv

And let me know the results

NOTE : make sure you defined the perl path in PATH variable

Code:
perl -F: -anE '$total += $F[1]; END { say $total/$. }' INPUTFILE

I get the answer by using cmd command. My perl program is at C:\Perl64\bin

Is this is the correct way to defined perl path on windows?

#C:\Perl64\bin\perl

or

#C:/Perl64/bin/perl

In the command prompt, type PATH and check whether the bin\perl is already included

PATH=C:\Program Files (x86)\Intel\Media SDK\3.0.442.32245 Beta3\bin\win32;C:\Per
l64\site\bin;C:\Perl64\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wb
em;C:\Windows\System32\WindowsPowerShell\v1.0\


In this folder I only include csv files.
