I have been using the following on my Raspberry pi which basically captures data from a weather hub I have connected to a USB port on the PI.

sudo tcpdump -A -n -p -l -i eth1 -s0 -w - tcp dst port 80 |
  stdbuf -oL strings -n8 |
  ./parser

The output buffer is read via a python script.

I want to move the whole process onto a windows (10) machine and so far I have the following working via CMD under Win10.

tcpdump -A -n -p -l -i eth1 -s0 -w - tcp dst port 80

The output however, is totally unreadable because I can not figure out the rest of the command under windows. Specifically

| stdbuf -oL strings -n8 |./parser

Any help with this would greatly be appreciated

I have tried this under PowerShell but I end up with the same garbled text

./tcpdump -A -n -p -l -i 5 | ForEach-Object {
  [Console]::WriteLine($_)
  [Console]::Out.Flush()
  $_
} | Set-Content program.log

======================================
When I issue the following command RaspPi

sudo tcpdump -A -n -p -l -i eth1 -s0 -w - tcp dst port 80 | stdbuf -oL strings -n8

I will get the following output

    tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes
