TABLE 2-18 Options for ps
Option Description How It Can Help
-e Displays information for every process. Identifies the process ID and the
executable.
-f Generates a full listing. Provides the following process
information: user ID, parent
process ID, time when executed,
and the path to the executable.
-o option Enables configurable output. The pid, pcpu, pmem, and
comm options display process ID, percent CPU consumption,
percent memory consumption, and the responsible
executable, respectively.

information. Knowing the
percentage of resource
consumption helps identify
processes that are affecting
performance and might be hung.
