Thanks, Hugo, I think you are right. So, the only way I can handle the problem is to save the pcap file and stop the tcpdump process.

Thanks, Guy, Actually I am capturing packets on an L3 device's interface. I did not include the part where I am logging into the device. So, I do need tcpdump here. Btw without -s, -n arguments, my capture works fine as you mentioned.

You can’t.

The 2 process are linked by the way you start them. So if you kill the first you also kill the second.

Hi Guy,

I have one more question for you. Sorry for pestering though.

How do I exit out of tcpdump which is passing the packets to wireshark without closing wireshark application?

`varuns@varuns ~ %  "tcpdump -c 30 -s 0 -U -n -w - -i et3_5_1" | wireshark -k -i -
tcpdump: listening, link-type EN10MB (Ethernet), capture size 262144 bytes
30 packets captured
30 packets received by filter
0 packets dropped by kernel`

Note: Performing ctrl+c on tcpdump, closes the wireshark GUI Application file without saving.

Note that Wireshark.org's Wireshark 3.2.x packages include installers for files that will put /Applications/Wireshark.app/Contents/MacOS into your path (it won't do so for *existing* Terminal windows, but all Terminal windows opened after that will pick it up automatically).
