Shell scripting - Adding many numbers in an array
I'd like to know what process is taking how much CPU, so a command like this ; ps waux | grep apache | awk '{print $3}' would give me
the following. However, I need to add those numbers one by one in order to see how much CPU my apache server is spending..
Any ideas? : )
Thanks in advance.
