NAME

   reordercap - Reorder input file by timestamp into output file

SYNOPSIS

   reordercap [ -n ] [ -v ] <infile> <outfile>

DESCRIPTION

   Reordercap is a program that reads an input capture file and rewrites
   the frames to an output capture file, but with the frames sorted by
   increasing timestamp.

   This functionality may be useful when capture files have been created
   by combining frames from more than one well-synchronised source, but
   the frames have not been combined in strict time order.

   Reordercap writes the output capture file in the same format as the
   input capture file.

   Reordercap is able to detect, read and write the same capture files
   that are supported by Wireshark.  The input file doesn't need a
   specific filename extension; the file format and an optional gzip
   compression will be detected automatically.  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
   reordercap handles this.

OPTIONS

   -n  When the -n option is used, reordercap will not write out the
       output file if it finds that the input file is already in order.

   -v  Print the version and exit.

SEE ALSO

   pcap(3), wireshark(1), tshark(1), dumpcap(1), editcap(1), mergecap(1),
   text2pcap(1), pcap-filter(7) or tcpdump(8)

NOTES

   Reordercap is part of the Wireshark distribution.  The latest version
   of Wireshark can be found at <https://www.wireshark.org>.

   It may make sense to move this functionality into editcap, or perhaps
   mergecap, in which case reordercap could be retired.
