+.Sh DESCRIPTION
+.Nm \&Ps
+displays a header line followed by lines containing information about your
+processes that have controlling terminals.
+This information is sorted by process
+.Tn ID .
+.Pp
+The information displayed is selected based on a set of keywords (see the
+.Fl L
+.Fl O
+and
+.Fl o
+options).
+The default output format includes, for each process, the process'
+.Tn ID ,
+controlling terminal, cpu time (including both user and system time),
+state, and associated command.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl a
+Display information about other users' processes as well as your own.
+.It Fl C
+Change the way the cpu percentage is calculated by using a ``raw''
+cpu calculation that ignores ``resident'' time (this normally has
+no effect).
+.It Fl e
+Display the environment as well.
+.It Fl h
+Repeat the information header as often as necessary to guarantee one
+header per page of information.
+.It Fl j
+Print information associated with the following keywords:
+user, pid, ppid, pgid, sess, jobc, state, tt, time and command.
+.It Fl L
+List the set of available keywords.
+.It Fl l
+Display information associated with the following keywords:
+uid, pid, ppid, cpu, pri, nice, vsz, rss, wchan, state, tt, time
+and command.
+.It Fl M
+Extract values associated with the name list from the specified core
+instead of the default
+.Dq Pa /dev/kmem .
+.It Fl m
+Sort by memory usage, instead of by process
+.Tn ID .
+.It Fl N
+Extract the name list from the specified system instead of the default
+.Dq Pa /vmunix .
+.It Fl O
+Add the information associated with the space or comma separated list
+of keywords specified, after the process
+.Tn ID ,
+in the default information
+display.
+Keywords may be appended with an equals (``='') sign and a string.
+This causes the printed header to use the specified string instead of
+the standard header.
+.It Fl o
+Display information associated with the space or comma separated list
+of keywords specified.
+Keywords may be appended with an equals (``='') sign and a string.
+This causes the printed header to use the specified string instead of
+the standard header.
+.It Fl p
+Display information associated with the specified process
+.Tn ID .
+.It Fl r
+Sort by current cpu usage, instead of by process
+.Tn ID .
+.It Fl S
+Change the way the process time is calculated by summing all exited
+children to their parent process.
+.It Fl T
+Display information about processes attached to the device associated
+with the standard input.
+.It Fl t
+Display information about processes attached to the specified terminal
+device.
+.It Fl u
+Display information associated with the following keywords:
+user, pid, %cpu, %mem, vsz, rss, tt, state, start, time and command.
+The
+.Fl u
+option implies the
+.Fl r
+option.
+.It Fl v
+Display information associated with the following keywords:
+pid, state, time, sl, re, pagein, vsz, rss, lim, tsiz,
+%cpu, %mem and command.
+The
+.Fl v
+option implies the
+.Fl m
+option.
+.It Fl W
+Extract swap information from the specified file instead of the
+default
+.Dq Pa /dev/swap .
+.It Fl w
+Use 132 columns to display information, instead of the default which
+is your window size.
+If the
+.Fl w
+option is specified more than once,
+.Nm \&ps
+will use as many columns as necessary without regard for your window size.
+.It Fl x
+Display information about processes without controlling terminals.
+.El
+.Pp
+A complete list of the available keywords are listed below.
+Some of these keywords are further specified as follows:
+.Bl -tag -width indent
+.It %cpu
+The cpu utilization of the process; this is a decaying average over up to
+a minute of previous (real) time.
+Since the time base over which this is computed varies (since processes may
+be very young) it is possible for the sum of all
+.Tn \&%CPU
+fields to exceed 100%.
+.It %mem
+The percentage of real memory used by this process.
+.It flags
+The flags (in hexadecimal) associated with the process as in
+the include file
+.Aq Pa sys/proc.h :
+.Bl -column SNOCLDSTOP SNOCLDSTOP

+.El
+.It lim
+The soft limit on memory used, specified via a call to
+.Xr setrlimit 2 .
+.It lstart
+The exact time the command started, using the ``%C'' format described in
+.Xr strftime 3 .
+.It nice
+The process scheduling increment (see
+.Xr setpriority 2 ) .
+.It rss
+the real memory (resident set) size of the process (in 1024 byte units).
+.It start
+The time the command started.
+If the command started less than 24 hours ago, the start time is
+displayed using the ``%l:ps.1p'' format described in
+.Xr strftime 3 .
+If the command started less than 7 days ago, the start time is
+displayed using the ``%a6.15p'' format.
+Otherwise, the start time is displayed using the ``%e%b%y'' format.
+.It state
+The state is given by a sequence of letters, for example,
+.Dq Tn RWNA .
+The first letter indicates the run state of the process:
+.Pp
+.Bl -tag -width indent -compact
+.It D
+Marks a process in disk (or other short term, uninterruptible) wait.
+.It I
+Marks a process that is idle (sleeping for longer than about 20 seconds).
+.It R
+Marks a runnable process.
+.It S
+Marks a process that is sleeping for less than about 20 seconds.
+.It T
+Marks a stopped process.
+.It Z
+Marks a dead process (a ``zombie'').
+.El
+.Pp
+Additional characters after these, if any, indicate additional state
+information:
+.Pp
+.Bl -tag -width indent -compact
+.It +
+The process is in the foreground process group of its control terminal.
+.It <
+The process has raised
+.Tn CPU
+scheduling priority.
+.It >
+The process has specified a soft limit on memory requirements and is
+currently exceeding that limit; such a process is (necessarily) not
+swapped.
+.It A
+the process has asked for random page replacement
+.Pf ( Dv VA_ANOM ,
+from
+.Xr vadvise 2 ,
+for example,
+.Xr lisp 1
+in a garbage collect).
+.It E
+The process is trying to exit.
+.It L
+The process has pages locked in core (for example, for raw
+.Tn I/O ) .
+.It N
+The process has reduced
+.Tn CPU
+scheduling priority (see
+.Xr setpriority 2 ) .
+.It S
+The process has asked for
+.Tn FIFO
+page replacement
+.Pf ( Dv VA_SEQL ,
+from
+.Xr vadvise 2 ,
+for example, a large image processing program using virtual memory to
+sequentially address voluminous data).
+.It s
+The process is a session leader.
+.It V
+The process is suspended during a
+.Xr vfork .
+.It W
+The process is swapped out.
+.It X
+The process is being traced or debugged.
+.El
+.It tt
+An abbreviation for the pathname of the controlling terminal, if any.
+The abbreviation consists of the two letters following
+.Dq Pa /dev/tty ,
+or, for the console, ``co''.
+This is followed by a ``-'' if the process can no longer reach that
+controlling terminal (i.e., it has been revoked).
+.It wchan
+The event (an address in the system) on which a process waits.
+When printed numerically, the initial part of the address is
+trimmed off and the result is printed in hex, for example, 0x80324000 prints
+as 324000.
+.El
+.Pp
+When printing using the command keyword, a process that has exited and
+has a parent that has not yet waited for the process (in other words, a zombie)
+is listed as ``<defunct>'', and a process which is blocked while trying
+to exit is listed as ``<exiting>''.
+.Nm \&Ps
+makes an educated guess as to the file name and arguments given when the
+process was created by examining memory or the swap area.
+The method is inherently somewhat unreliable and in any event a process
+is entitled to destroy this information, so the names cannot be depended
+on too much.
+The ucomm (accounting) keyword can, however, be depended on.
+.Sh KEYWORDS

+meanings.
+Several of them have aliases (keywords which are synonyms).
