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
