How to Save PCAP File to Text File Using Tshark from Command Line
Analyzing network packets is a crucial task for network engineers and security professionals. One common format for storing packet data is the PCAP (Packet Capture) file, which can be generated by tools like Wireshark. While Wireshark provides a user-friendly graphical interface to convert these files into various formats, not everyone prefers to work with GUIs. So, how can you use Tshark, the command-line version of Wireshark, to save a PCAP file to a text file? If you're looking for a quick and efficient way to achieve this, you've come to the right place!
In this guide, we'll drill down into the process of converting a PCAP file (.pcap) into a text file format (specifically the K12 text format) using the command line. Let’s dive in!
Understanding the Problem
You might already know that Wireshark allows you to save a .pcap file in multiple text formats, referred to collectively as "text file formats." These formats may include:
Packet summaries
Packet details
Hex dumps
CSV files
Custom fields in various formats (like PSML, PDML, JSON, etc.)
What is K12 Text Format?
The term "K12 text format" refers to a specific way of saving packet capture data, which some Tektronix equipment can generate. It's reminiscent of the raw hexadecimal data formats, but packaged with additional metadata for better usability. So, the goal is to replicate what happens when you use Wireshark's "Save As... K12 text file" option directly from the command line.
The Solution
Using Tshark
You can achieve your goal with the following command syntax:

Alternate Method: Using Editcap
If you prefer, you can also use another command-line tool called editcap, designed for editing and manipulating capture files. The command is similar:

This method gives you the same output file as the one you'd obtain using Tshark, but it might be more straightforward depending on your needs.
Conclusion
By following the steps outlined above, you can effortlessly convert a PCAP file into a K12 text format file using either Tshark or editcap. This flexibility allows you to work entirely from the command line, maintaining efficiency if you prefer not to engage with a graphical user interface.
Now you're equipped with the knowledge to tackle PCAP files via the command line effectively. Whether you are analyzing data for network troubleshooting, performance monitoring, or security analysis, being comfortable with command-line tools will enhance your workflow significantly.
Happy capturing!
