ps command options
Option Description Application
-e Displays information on various
processes.
Allows you to view the process IDs
and files that can be executed.
-f Generates a complete list. Allows you to view process
information such as the user ID, the
parent process ID, the execution
time, and the paths to the executed
files.
-o option Selects any items from those that
can be configured as outputs. The
pid, pcpu, pmem, and comm
options display the process ID, CPU
usage, memory usage, and
corresponding executable files,

important information. By
determining the resource usage

C.6 ps Command
The ps command displays a list of process statuses. When no options are specified,
the command outputs information on those processes that have the same execution
user ID as the user executing the command and the same control terminal.
If you specify an option, output information is controlled by the option.
Table C-6 lists the options of the ps command and how those options are useful for
troubleshooting.
The following example shows the output from the ps command.
