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.

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.
