CAPTYPE(1) CAPTYPE(1)
captype - Prints the types of capture files
captype <infile> ...
captype -h|--help
captype -v|--version
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.
-h|--help
Print the version number and options and exit.
-v|--version
Print the full version information and exit.
--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.
