The protStat script can be used to sort, filter and manipulate one of the files generated by one of those plugins:

  • protoStats: _protocols.txt
  • icmpDecode: _icmpStats.txt
  • igmpDecode: _igmpStats.txt
  • nDPI: _nDPI.txt

  • Sort a file by packets:

    $ protStat file.txt
  • Sort a file by bytes:

    $ protStat -b file.txt
  • Sort in reverse order:

    $ protStat -r file.txt
  • Only display values with packet probability greater than 50%:

    $ protStat -p 50 file.txt
  • Only display values with byte probability smaller than 1%:

    $ protStat -b -p -1 file.txt
  • Only display the 5 values with highest byte count:

    $ protStat -b -n 5 file.txt
  • Only display the 10 values with lowest packet count:

    $ protStat -n -10 file.txt
  • For more details about protStat, run:

    $ protStat --help


  • Decode Tranalyzer status bitfield

    $ tawk -V name
    $ tawk -V name=value
  • List the column names and numbers of a flow file:

    $ tawk -l file_flows.txt
  • List the functions provided by tawk:

    $ tawk -g

    Alternatively, refer to the Alphabetical List of TAWK Functions.

  • Access the documentation of a tawk function:
