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
