captype - Man Page

Prints the types of capture files


capinfos <infile> ...


Captypes is a program that opens one or more capture files and prints the capture file type of each <infile>.

Capinfos 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 <> is a detailed description of the way Wireshark handles this, which is the same way Capinfos handles this.
