If these are fixed-width fields:

Code:

$ cat fsplit.awk

BEGIN {
        OFS=","
        # Big list of character ranges, split into A[1]="1-4", ...
        X=split("1-4,5-5,11-12,13-13,14-16,17-18,20-23,24-27,28-31,32-32,33-35,36-38", A, ",");
        for(N=1; N<=X; N++)
        {
                split(A[N], B, "-"); # Split "1-4" into B[1]="1", B[2]="4"
                delete A[N];
                S[N]=B[1]; # Keep the same
                E[N]=(B[2]-B[1])+1; # Calculate the length from the offset
        }
}

{
        STR=$0
        $0=""
        # Assemble a big list of fields from each given position, stripping
        # the appropriate section of string out of STR.
        for(N=1; N<=X; N++) $N=substr(STR, S[N], E[N]);

# print every line.
} 1

$ awk -f fsplit.awk data

I suspect the fields will be wrong for your data given the lack of code tags, but you can modify the numbers as you see fit. It's just

Code:

START1-END1,START2-END2,START3-END3,...

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
