NAME

       captype - Prints the types of capture files

SYNOPSIS

       captype <infile> ...

       captype -h|--help

       captype -v|--version

DESCRIPTION

       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, zstd or lz4 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.

OPTIONS

       -h|--help
           Print the version number and options and exit.

       -v|--version
           Print the full version information and exit.

DIAGNOSTIC OPTIONS

       --log-level <level>
           Set the active log level. Supported levels in lowest to highest order are "noisy",
           "debug", "info", "message", "warning", "critical", and "error". Messages at each level
           and higher will be printed, for example "warning" prints "warning", "critical", and
           "error" messages and "noisy" prints all messages. Levels are case insensitive.

       --log-fatal <level>
           Abort the program if any messages are logged at the specified level or higher. For
           example, "warning" aborts on any "warning", "critical", or "error" messages.

       --log-domains <list>
           Only print messages for the specified log domains, e.g. "GUI,Epan,sshdump". List of
           domains must be comma-separated. Can be negated with "!" as the first character
           (inverts the match).

       --log-debug <list>
           Force the specified domains to log at the "debug" level. List of domains must be
           comma-separated. Can be negated with "!" as the first character (inverts the match).

       --log-noisy <list>
           Force the specified domains to log at the "noisy" level. List of domains must be
           comma-separated. Can be negated with "!" as the first character (inverts the match).

       --log-fatal-domains <list>
           Abort the program if any messages are logged for the specified log domains. List of
           domains must be comma-separated.

       --log-file <path>
           Write log messages and stderr output to the specified file.
