SYNOPSIS
ps [ -apr ]
psu [ -apr ] [ user ]
DESCRIPTION

about processes started by user (default $user).
For each process reported, the user, process id, user time, system
time, size, state, and command name are printed. State is one of the
following:
Moribund Process has exited and is about to have its resources re‐
claimed.
Ready on the queue of processes ready to be run.
Scheding about to be run.
Running running.
Queueing waiting on a queue for a resource.
Wakeme waiting for I/O or some other kernel event to wake it up.

amined.

Fault servicing a page fault.
Idle waiting for something to do (kernel processes only).

Pageout paging out some other process.

The -r flag causes ps to print, before the user time, the elapsed real
time for the process.
The -p flag causes ps to print, after the system time, the baseline and
current priorities of each process.
The -a flag causes ps to print the arguments for the process. Newlines
in arguments will be translated to spaces for display.
