CPU affinity-aware `ps’

[code lang=”bash”]ps -eo pid,tid,class,rtprio,ni,pri,pcpu,stat,wchan:14,comm,psr[/code]

The last number is the CPU the process is currently waiting on.  Quite useful when used in conjunction with `top’, as hitting the number 1 while in interactive mode will display the per-CPU usage.  Helpful to find iowait.
