How to calculate the entropy of a single directory that contains many files
Hello,
I'm new member of shell scripting and i face some difficulties. To begin, i try to write an algorithm that calculate from one directory containing nfdump files (288) the entropy of one day 24hours. Each of the file is 5 min interval
(nfdump -r nfcapd.200908250000 -s srcip) 1st
(nfdump -r nfcapd.200908250005 -s srcip) 2nd
(nfdump -r nfcapd.200908250010 -s srcip) 3rd
...
(nfdump -r nfcapd.200908252350 -s srcip) last
taking the flows (first 10) to calculate the entropy of the first 5 min interval i did it (i hope so in the right way) and i took the results of the 1st 5 min interval entropy. the code that i have written is:
I used the shannon entropy formula for this.
My main problem now is how to make a matrix -array of all 288 files of 5 min interval and how is possible to combine the above algorithm with the matrix? Please if someone knows how to do this just to give me some help - advise
Thanks
