Hey,
This is a string command that I am proud of. Wanted to share it with you all. I have finally figured out how to print the process using the highest cpu. You can use this in many ways. I wanted to capture it in a variable, see third code block.

1.

Code:

[root@vmradio01 ~]# ps -eo pid,user,%cpu,args --sort %cpu | awk '/httpd/{n=n<$3?$3:n}END{print n}'
2.3

Here I separate the first field for the variable using awk:

2.

Code:

[root@vmradio01 ~]# ps -eo pid,user,%cpu,args --sort %cpu | awk '/httpd/{n=n<$3?$3:n}END{print n}' | awk -F \. '{print $1}'
2

3. Assign it to a variable called highcpuproc.

Code:

[root@vmradio01 ~]#highcpuproc=`ps -eo pid,user,%cpu,args --sort %cpu | awk '/httpd/{n=n<$3?$3:n}END{print n}' | awk -F \. '{print $1}'`

LOVE LINUX
Jaysunn
