reordercap – Reorder input file by timestamp into output file
reordercap [ -n ] [ -v ]
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
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 of the way Wireshark handles this, which is the same way
reordercap handles this.
-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.
Reordercap is part of the Wireshark distribution. The latest version
of Wireshark can be found at
It may make sense to move this functionality into editcap, or perhaps
mergecap, in which case reordercap could be retired.
