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
