.SH "DESCRIPTION"
.sp
\fBCaptype\fP is a program that opens one or more capture files and
prints the capture file type of each <\fIinfile\fP>.
.sp
\fBCaptype\fP is able to detect and read the same capture files that are
supported by \fBWireshark\fP.
The input files don\(cqt 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
\c
.URL "https://www.wireshark.org/docs/man\-pages/wireshark.html" ""
is a detailed description of the way \fBWireshark\fP handles this, which is
the same way \fBCaptype\fP handles this.
