I require some help with a homework question. I have the following data in a file that I need to parse:

              Output-------------------------- Input---------------- Random----
              -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec  %CPU /sec  %CPU
         50.0 36112 34.1 138026  1.9 179048  7.0 51361 51.1 312242  4.3 15211.4 10.3

What I need is a way to extract the data from the Block column for both the output and input columns. For example:

Output Block:
K/sec: 138026
%CPU:  1.9

Input Block:
K/sec: 312242
%CPU:  4.3

I am limited to using sed, awk, cut, and grep.

    parse_data.txt:- Is the file where the data is present.

    more parse_data.txt | grep -v “-” | sed ‘s/\ /\ /g’ | awk ‘{print $4 ” “$5 ” ” $10 ” ” $11}’

    CPU and k/sec data with respect Output and Input block
    is been retrieved, as shown below,

    Output got is:

     K/sec  %CPU K/sec  %CPU
 138026 1.9  312242 4.3

    Hope this solves your problem!!!!!
