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, 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 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

       This is the manual page for Reordercap 3.6.2. 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.

       HTML versions of the Wireshark project man pages are available at
       https://www.wireshark.org/docs/man-pages.
