 -w, --word-regexp
        Select only those lines containing matches that form  whole words.  The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word constituent character.  
	This option has no effect if -x is also specified.

 # ps axo ppid,pid,stat,comm | grep -w defunct | awk '{print $2 }' | xargs kill -9

 # ps -eo ppid,pid,stat,comm,user,args,pcpu,pmem | sor -k2 -r | head -10
