captype - Prints the types of capture files
captype <infile> ...
Captype is a program that opens one or more capture files and prints the capture file type of each <infile>.
Captype is able to detect and read the same capture files that are supported by Wireshark. The input files don't need a specific filename extension; the file format and an optional gzip compression will be automatically detected. Near the beginning of the DESCRIPTION section of wireshark(1) or https://www.wireshark.org/docs/man-pages/wireshark.html is a detailed description of the way Wireshark handles this, which is the same way Captype handles this.
pcap(3), wireshark(1), mergecap(1), editcap(1), tshark(1), dumpcap(1), capinfos(1), pcap-filter(7) or tcpdump(8)
