NAME
flow-merge -- Merge flow files.
SYNOPSIS
flow-merge [-aghm] [-b big|little] [-C comment] [-d debug_level] [-o filename] [-z z_level] [file|directory ...]
DESCRIPTION
The flow-merge utility processes files and/or directories of files in
the flow-tools format. The resulting merged data set is written to the
standard output or file specified by -o. If file is a single dash
(`-') or absent, flow-merge will read from the standard input. Unlike
flow-cat, flow-merge interleaves flow records preserving the relative
chronological order.
OPTIONS
-a Do not ignore filenames that begin with tmp.
- -b big|little
- Byte order of output.
- -C Comment
- Add a comment.
- -d debug_level
- Enable debugging.
- -g Sort file list by capture start time before processing.
- -h Display help.
- -m Disable the use of mmap().
- -p Preload headers. Use to preserve meta information such as
- lost flows.
- -o file Write to file instead of the standard out.
- -z z_level
- Configure compression level to z_level. 0 is disabled (no compression), 9 is highest compression.
- file|directory...
- Process the files and/or directory.
EXAMPLES
- Merge all flow files begining with ft-v05.2001-05.01, use flow-print to
display the results.
- flow-merge ft-v05.2001-05-01.* | flow-print
