It report processors related statistics.

The biggest benefit here is that sar makes the data available on an ongoing basis and is therefore more useful for obtaining long-term averages, or for the production of CPU utilization Here's a version that works with both implementations: top -b -n2 -p 1 | fgrep "Cpu(s)" | tail -1 | awk -F'id,' -v prefix="$prefix" '{ split($1, vs, ","); v=vs[length(vs)]; sub("%", "", Thanks for filling in the gaps.
