12 Reordercap is a program that reads an input capture file and rewrites
13 the frames to an output capture file, but with the frames sorted by
14 increasing timestamp.
15
16 This functionality may be useful when capture files have been created
17 by combining frames from more than one well-synchronised source, but
18 the frames have not been combined in strict time order.
19
20 Reordercap writes the output capture file in the same format as the
21 input capture file.
22
23 Reordercap is able to detect, read and write the same capture files
24 that are supported by Wireshark. The input file doesn't need a
25 specific filename extension; the file format and an optional gzip
26 compression will be detected automatically. Near the beginning of the
27 DESCRIPTION section of wireshark(1) or
28 <https://www.wireshark.org/docs/man-pages/wireshark.html> is a detailed
29 description of the way Wireshark handles this, which is the same way
30 reordercap handles this.
31
33 -n When the -n option is used, reordercap will not write out the
34 output file if it finds that the input file is already in order.
35
36 -v Print the version and exit.

43 Reordercap is part of the Wireshark distribution. The latest version
44 of Wireshark can be found at <https://www.wireshark.org>.
45
46 It may make sense to move this functionality into editcap, or perhaps
47 mergecap, in which case reordercap could be retired.
