Field separation in tshark using Wireshark

Tshark is a command-line tool that is part of the Wireshark suite of network analysis tools. It is used to capture and analyze network traffic, and can also be used to filter and display packets based on specific criteria.

To separate fields in tshark using Wireshark, you can use the -T option followed by the name of the output format you want to use. For example, to display the source and destination IP addresses of packets in the pcap file "capture.pcap", you can use the following command:

tshark -r capture.pcap -T fields -e ip.src -e ip.dst

In this command, the -r option specifies the name of the input pcap file, while the -T option specifies the output format as "fields". The -e option is used to specify the fields to be displayed, with "ip.src" and "ip.dst" specifying the source and destination IP addresses respectively.

You can also use other output formats, such as "json" or "pdml", by specifying them with the -T option. For example, to output packets in JSON format, you can use the following command:

tshark -r capture.pcap -T json

This will output all packets in JSON format. You can also specify specific fields to be included in the JSON output using the -e option, as shown in the first example.
