so this is what i want to do. i have data that looks like this:

The actual data is of course much bigger than this. But the above is the layout. What i want to do is grab certain values under each Array.

So for Array B, say i want to grab the value of "Sectors Per Track", how do i do so? in this case, i'd like an output similar to: ArrayB=(Sectors Per Track,32).

My first instinct is to run a while loop on the command that produces the data. but i'm not sure of how to make the while loop smart enough to know when each Array begins and when it ends.

I'm hoping awk can be used here.

The ultimate goal here is to be able to grep for certain things under each array and be able to tie thing being grepped for back to the array, as i bolded above.

Another example, for Array A, see if there are any strings that contain the word "Fail". If there are, output the lines. ex. ArrayA=(physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SAS, 300 GB, Failed)

Use the awk pattern

$1 ~ /^Array:/

This delimits the "array" data.

i think i need something more.

i tried:

while read line

do

echo $line
awk '$1 ~ /Array:/' 

done < data.txt.

but it only gives me:

   Array: A
   Array: B
   Array: C
Smart Array P410i in Slot 0
