@Rudic, sorry that my post was misleading. Are you right, the input file should be split into 8 smaller files also maintaining the integrity of each chunk of lines in the input file.

-> Each of the 8 smaller output files should start with dn: and end with an empty line.
-> optimal position of a file break, It should be the "empty line" that is separating the input file chunks. the expected it to have the input file split into 8 smaller files without disturbing the order/integrity of each chunks.

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.

       -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
