Again, the PID, TTY, CPU time, and command are displayed. However, the UID is also displayed, as is the PID of the parent process identifier (PPID), along with the starting time of the process (STIME). In addition, a deprecated column (C) is used to display processor utilization. To obtain the maximum detail possible, you can also use the l option, which means long and long it certainly is, as shown in this example:

If you re a system administrator, you re probably not interested in the status of just your own processes; you probably want details about all or some of the processes actively running on the system, and you can do this in many ways. You can generate a process list using the A or the e option, for example, and either of these lists information for all processes currently running on the machine:

# ps -A PID TTY 0 1 2 3 258 108 255 60 62 157 110 112 165

Again, the default display of PID, TTY, CPU time, and command is generated. The processes listed relate to the scheduler, init, the system logging facility, the NIS cache, and several other standard applications and services. It is good practice for you to become familiar with the main processes on your system and the relative CPU times they usually consume. This can be useful information when troubleshooting or when evaluating security. One of the nice features of the ps command is the ability to combine multiple flags to print out a more elaborate process list. For example, you can combine the A option (all processes) with the f option (full details) to produce a process list with full details. Here s the full details for the same process list:
# ps -Af UID root root root root root root root root root root root
PID 0 1 2 3 258 108 255 60 62 157 110

Another common use for ps is to print process information in a format that is suitable for the scheduler:
% ps -c PID CLS PRI TTY 29081 TS 48 pts/8 29085 TS 48 pts/8
TIME CMD 0:00 ksh 0:00 bash
Doing this can be useful when used in conjunction with the priocntl command, which displays the parameters used for process scheduling. This allows administrators, in particular, to determine the process classes currently available on the system, or to set the class of a specific process to interactive or time-sharing. You can obtain a list of all supported classes by passing the l parameter to priocntl:
# priocntl -l CONFIGURED CLASSES ================== SYS (System Class) TS (Time Sharing) Configured TS User Priority Range: -60 through 60 IA (Interactive) Configured IA User Priority Range: -60 through 60 FX (Fixed priority) Configured FX User Priority Range: 0 through 60
You can combine this with a f full display flag to ps c to obtain more information:
