Bash script how to display matched words in custom order

The following is the output of the command ads2 cls create

kernel with pid 7148 (port 9011) killed

        nodes {
            node {
                name = "FDT-C-VM-xxxx";
                address = "http://fxx-x-xx-0093.xxx.intern:xxxx/";
                state = "3";
            }
            node {
                name = "xxx-x-xxx-xxx";
                address = "http://1xx.16.xx.xx:9011/";
                state = "3";
            }
        }

However, I'm trying to extract the value of name and state for each node, save them in a variable and display them in the following order:

**#example output**

Node fdt-c-agx-xxx has state 3
Node FDT-C-VM-xxx has state 3

Till now i, with the help of this so much powerful learning site, could extract the values of name and state by executing the following:

cls="$(ads2 cls create | grep '\(state\|name\) =' | cut -d '"' -f 2)"

Now if i print cls variable, i get the following:

FDT-C-VM-xxx
3
FDT-C-AGX-xxx
3

First Question:

How can i display the result like the one above in the **#example output**?

Second question

With this implementation, how can I check the value of state varaiable for both nodes in order to print something like

if node1State = 3 && node2State = 3; then
echo "Sucess"
else 
echo "Failed"

Solution

Since the output seems to be json, you should really use a json parser such as jq but in the absence of jq you can use awk and combine the requirements for question one and two:

ads2 cls create | awk -F [\"] '/^>>> cluster established .../ { strt=1 } strt!=1 { next } $1 ~ "name" { cnt++;nam[cnt]=$2 } $1 ~ "state" { stat[cnt]=$2;print "Node "nam[cnt]" has state "$2 } END { if (stat[1]=="3" && stat[2]=="3") { print "Success" } else { print "Failed" } }'

Explanation:

 ads2 cls create | awk -F [\"] '                                         # Set the field delimiter to a double quote
/^>>> cluster established .../ { 
               strt=1                                                    # If the line starts with ">>> cluster established ...", set a variable strt to 1
            }
 strt!=1    { 
               next                                                      # If strt is not equal to 1, skip to the next line
            }
 $1 ~ "name" { 
               cnt++;                                                    # If the first field contains name, increment a cnt variable
               nam[cnt]=$2                                               # Use the cnt variable as the index of an array called nam with the second field the value
             }  
 $1 ~ "state" {   
               stat[cnt]=$2;                                             # When the first field contains "state", set up another array called stat
               print "Node "nam[cnt]" has state "$2                      # Print the node name as well as the state
               } 
           END { 
                 if (stat[1]=="3" && stat[2]=="3") { 
                   print "Success"                                       # At the end of processing, use the array to determine whether there is a success of failure.
                 } 
                 else { 
                   print "Failed" 
                 } 
                }'
