flow-merge(1) General Commands Manual flow-merge(1)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
