Explanations

- ps Report a snapshot of the current processes
- -e Select all processes
- o Specify user-defined format
- pmem,pcpu,pid,args user-defined format: memory,cpu, pid number and command
- | tail -n +2 Output lines starting to the second line (to avoid column names such %MEM, etc ...)
- | sort -rnk 1 reverse (r), numeric sort (n) by column 1 (memory)
- | sort -rnk 2 reverse (r), numeric sort (n) by column 2 (cpu)
- | head output the 10 first lines
Enjoy !!!

 
By myself: below is what I want and recommend
[root@vm-www ~]# pidstat | tail -n +4 |grep mysql | sort -rnk 6 | head -5
