Hello,

I am having a problem trying to get started with Sed and Awk which I believe is the best solution to my current problem.

I have a text file which repeats this:
Code:

Not a real host            ##<--- if Not a real host ignore all lines until next blank line
uuid (MI)
                : 239043289-3249329-239408932-48329403
           uid: 239490329-9504835-943509348-39858439
        name: test1
        vmst:  data
          net:  data

uuid (MI)                   ##<---- Is a real host so parse the number directly below and parse the name field and move on
              : 320-9493493-3904239-3940392-4239408329492
         uid: 3040320-23-3294023890234-329482390-239483
      name: test2
      vmst: data
        net: data

repeating
.
.
.


I am simply trying to read line by line, if its a real host parse the first number and name and move on to next block

correct output:
320-9493493-3904239-3940392-4239408329492
test2

So far I am thinking I will search for text "Not a real host", then delete all lines until next empty line and do this for the entire file.

Then I will read entire file again and search for string "uuid (MI)" and just parse out the next line below for the number and then the 3 line below that for the name.

Perhaps someone out there can provide me feedback or a better way to do this?

Thanks in advance,

Joe
