# captype

## 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.

## 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.
