NAME

6       captype - Prints the types of capture files
7

SYNOPSIS

9       captype [ -h ] [ -v ] <infile> ...
10

DESCRIPTION

12       Captype is a program that opens one or more capture files and prints
13       the capture file type of each <infile>.
14
15       Captype is able to detect and read the same capture files that are
16       supported by Wireshark. The input files don’t need a specific filename
17       extension; the file format and an optional gzip, zstd or lz4
18       compression will be automatically detected. Near the beginning of the
19       DESCRIPTION section of wireshark(1) or
20       https://www.wireshark.org/docs/man-pages/wireshark.html is a detailed
21       description of the way Wireshark handles this, which is the same way
22       Captype handles this.

DIAGNOSTIC OPTIONS

34       --log-level <level>
35           Set the active log level. Supported levels in lowest to highest
36           order are "noisy", "debug", "info", "message", "warning",
37           "critical", and "error". Messages at each level and higher will be
38           printed, for example "warning" prints "warning", "critical", and
39           "error" messages and "noisy" prints all messages. Levels are case
40           insensitive.
41
42       --log-fatal <level>
43           Abort the program if any messages are logged at the specified level
44           or higher. For example, "warning" aborts on any "warning",
45           "critical", or "error" messages.
46
47       --log-domains <list>
48           Only print messages for the specified log domains, e.g.
49           "GUI,Epan,sshdump". List of domains must be comma-separated.
50
51       --log-debug <list>
52           Force the specified domains to log at the "debug" level. List of
53           domains must be comma-separated.
54
55       --log-noisy <list>
56           Force the specified domains to log at the "noisy" level. List of
57           domains must be comma-separated.
58
59       --log-file <path>
60           Write log messages and stderr output to the specified file.
