Question

Is there a way to grep a single line of output with items separated by spaces and only output the exact block of string that begins and ends with spaces?

For instances, here is the output:

I only want CPUx_Temp blocks from the whole output.

Answer 1

I'm not sure grep along will do it. Say 'foo' is a file containing your input line as shown. The code is: awk 'BEGIN{FS=";"};{for (i=1;i<=NF;i++) {if ($i~/Processor_[0-9]_CPU/) print $i} }' foo | cut -d_ -f5-9 Output: CPU1_Temp=47 CPU2_Temp=55 You requested capitalized instances of 'CPU' in proximity to their temps, so I think this is what you were looking for.

Answer 2

You can use grep also: grep -Po 'CPU[0-9]_Temp=[0-9].?'
