Hi everyone,

I am looking for a command to get CPU usage in percentage. normally top command do that but not in DSL distribution.

There is CPU usage in Desktop but I don't know how to get this information. My aim is to get it from command line.

Thanks in advance.

CPU total load% is shown in the upper right corner of your desktop.

I dont know how accurate it is, because sometimes it shows CPU usage 141%... eg. more than 100% which is weird..

Thanks,

But, there is any way to get cpu load from command line. I want to integrate it to script shell.

The differences in top is probably a result of dtf using gnu-utils instead of the default Busybox.

One way to get cpu usage is with the command "cat /proc/loadavg" or "cat /proc/stat", although I'm not certain how to read them....
