Retrieve CPU usage and memory usage of a single process on Linux?

Question

I want to get the CPU and memory usage of a single process on Linux - I know the PID. Hopefully, I can get it every second and write it to a CSV using the \'watch\' command

Answer 1

Based on @Neon answer, my two cents here:

pidstat -h -r -u -v -p $(ps aux | grep  | awk '{print $2}' | tr '\n' ',')
