REORDERCAP(1) REORDERCAP(1)
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.

This is the manual page for
Reordercap 3.6.22.
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
