SHOW TOP 10 PROCESSES CONSUMING MOST CPU

I can't understand problems from my linux system ..

Quote:

$ watch 'ps -eo pcpu, pid, user, args | sort -k 1 -n -r | head -10'

While issuing this query please see attached screen shot ..
then i checked to find error but not ..

Quote:

[root@localhost ~]# echo $?
0

Quote:

[root@localhost ~]# watch ps aux | grep 4851 | grep -v grep

My system hangs ... Still no output .. every time i use ctrl +c

When you have problems with compound commands, run each of the commands separately, and make sure they work.
The manpage for watch has some comments about the effects of quoting.

Here is what I got from that command:

Code:

Every 2.0s: ps -eo pcpu, pid, user, args | sort -k 1 -n...  Fri Nov 16 17:02:21 2012

error: improper list

Usage:
 ps [options]

 Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
 for additional help text.

For more details see ps(1).
