The percentage (29.0%) indicates the percentage of the CPU's time that the process used while it ran. The sum of the user and system times is the total CPU time of the process. The program myprog used 1.406 seconds of user time, 0.042 seconds of system time, and 4.96 seconds of real time.
The following is an output example for users in the csh or tcsh shells: 1.406u 0.042s 0:04.96 29.0% 2+5k 0+1io 0pf+0w Replace myprog with the name of the program you are running. If you want to see a grand total of CPU time for a program when it finishes running, you can use the time command. In Unix, you can see CPU usage on a job that is running in a number of ways, as described below: The time command For more information about the nice command, at the Unix prompt, enter: man nice If you are concerned about slowing the system down, you can use the nice command to lower your program's priority.
