CAPTYPE(1) CAPTYPE(1)
NAME
captype - Prints the types of capture files
SYNOPSIS
captype [ -h ] [ -v ] <infile> ...
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.

Set the active log level. Supported levels in lowest to highest

"error" messages and "noisy" prints all messages. Levels are case
insensitive.

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.

Only print messages for the specified log domains, e.g.
"GUI,Epan,sshdump". List of domains must be comma-separated.
--log-debug <list>
Force the specified domains to log at the "debug" level. List of
domains must be comma-separated.
