I meant to change every space to newline, to only get the last word in the file. But my code was incorrect, changing newlines to spaces instead of the other way around.
Code:
mpstat 1 2 | tr ' ' '\n' | tail -n 1
If you need the last word of every line, try something like this:
Code:
awk '{print $NF}'
Then use head/tail/grep to skip the lines you dont want.
My problem is idle column varies with OS version so I am trying for generalized solution to get %idle column irrespective of the OS version. the solution I tried is working fine but failing in Average column as number of columns differ.
So test for "Average" and use $(i-1). But seeing as how that what you want, why not just use it ?.
There is also no need for grep - you can do that elimination in your awk.
