`time cp Location`, will give you processing time, what metric are you after? – Lawrence Cherone Jun 30 '20 at 11:34

percent is a rolling average :/ if it takes 20mins how would 15% make sense, some details on conversion from time to utilisation [here](https://stackoverflow.com/questions/28240978/how-to-interpret-cpu-time-vs-cpu-percentage) – Lawrence Cherone Jun 30 '20 at 11:36

I recently found a tool which measures time, cpu usage, memory usage all at once. Its called /usr/bin/time and should be installed via apt

htop is a graphical solution in the shell - maybe this one helps
There you can search for it.

top command will show you memory and CPU usage,
you can pipe with grep
