If the -w option is not specified, TShark writes to the standard output the text of a decoded form of the packets it captures or reads. If the zlib library is not present, TShark will compile, but will be unable to read compressed files. Near the beginning of the DESCRIPTION section of wireshark(1) or is a detailed description of the way Wireshark handles this, which is the same way Tshark handles this.Ĭompressed file support uses (and therefore requires) the zlib library. The input file doesn't need a specific filename extension the file format and an optional gzip compression will be automatically detected. TShark is able to detect, read and write the same capture files that are supported by Wireshark. It will use the pcap library to capture traffic from the first available network interface and displays a summary line on stdout for each received packet. Without any options set, TShark will work much like tcpdump. TShark's native capture file format is libpcap format, which is also the format used by tcpdump and various other tools. It lets you capture packet data from a live network, or read packets from a previously saved capture file, either printing a decoded form of those packets to the standard output or writing the packets to a file.
