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.
DIAGNOSTIC OPTIONS
--log-level <level>
Set the active log level. Supported levels in lowest to highest
order are "noisy", "debug", "info", "message", "warning",
"critical", and "error". Messages at each level and higher will be
printed, for example "warning" prints "warning", "critical", and
"error" messages and "noisy" prints all messages. Levels are case
insensitive.
--log-fatal <level>
Abort the program if any messages are logged at the specified level
or higher. For example, "warning" aborts on any "warning",
"critical", or "error" messages.
--log-domains <list>
Only print messages for the specified log domains, e.g.
"GUI,Epan,sshdump". List of domains must be comma-separated.
--log-debug <list>
Force the specified domains to log at the "debug" level. List of
domains must be comma-separated.
--log-noisy <list>
Force the specified domains to log at the "noisy" level. List of
domains must be comma-separated.
--log-file <path>
Write log messages and stderr output to the specified file.

NOTES
This is the manual page for Reordercap 4.0.11. 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.
