NAME

flow-cat - Concatenate flow files

SYNOPSIS

flow-cat [ -aghmp ] [ -b big|little ] [ -C comment ] [ -d debug_level ] [ -o filename ] [ -t start_time ] [ -T start_time ] [ -z z_level ] [ file|directory... ]

DESCRIPTION

The flow-cat utility processes files and/or directories of files in the flow-tools format. The resulting concatenated data set is written to the standard output or file specified by -o. If file is a single dash (`-') or absent, flow-cat will read from the standard input.

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.
-t start_time
Select flow files up to start_time. If used with -T select files between start_time and end_time.
-T end_time
Select flow files after end_time. If used with -t select files between start_time and end_time.
-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.

TIME/DATE PARSING

start_time and end_time parsing is implemented with getdate.y, a commonly used function to process free-form time date specifications. Example usage borrowed from cvs: 1 month ago 2 hours ago 400000 seconds ago last year last Monday yesterday a fortnight ago 3/31/92 10:00:07 PST January 23, 1987 10:05pm 22:00 GMT

EXAMPLES

Concatenate all flow files begining with ft-v05.2001-05.01, use flow-print to display the results.

flow-cat ft-v05.2001-05-01.* | flow-print

Concatenate flow files in /flows/krc4, store store the output in compressed.flows at compression level 9 (best). The headers are preloaded so various metadata such as the flow count is correct in the result. Filenames begining with tmp which are typically in-progress flow files from flow-capture are not processed.

flow-cat -p -z9 /flows/krc4 > compressed.flows

BUGS

None known.
