NAME

       flow-split -- Split flow files into smaller files.

SYNOPSIS

       flow-split [-gGhn]  [-b big|little]  [-C comment]  [-d debug_level]  [-N nflows]  [-o outfile_basename]	[-T nseconds]  [-z z_level]

DESCRIPTION

       The flow-split utility will split a flow file into smaller files based on the the number of flows or the ammount of time that has passed.

OPTIONS

       -b big|little
		 Byte order of output.

       -C Comment
		 Add a comment.

       -d debug_level
		 Enable debugging.

       -g	 Split on source tag.

       -G	 Split on destination tag.

       -h	 Display help.

       -n	 Use symbols for tag field in filename.

       -N nflows Split after processing nflows.

       -o outfile_basename
		 The basename of the resulting files.

       -T nsecond
		 Split after processing an interval of nseconds flows.

       -z z_level
		 Configure compression level to  z_level.  0 is disabled (no compression), 9 is highest compression.

EXAMPLES

       Create 1 minute flow files from the flow archive in /flows/krc4.  Store the results in /flows/krc4.split

	 flow-cat /flows/krc4 | flow-split -T60 -o /flows/krc4.split/1min.
