Introduction:
SPS is a intended to be used as a replacement for the standard
ps(1) program. Its advantages over ps(1) are that it shows more
useful information, that the displayed information is more
comprehensible and that it is faster.
SPS is currently implemented for the following operating systems and
architectures. The corresponding Makefiles are also shown here:
Makefile.4.1 Standard 4.1bsd for Vax
Makefile.4.2 Standard 4.2bsd, Ultrix 1.x for Vax
Makefile.4.3 Standard 4.3bsd (or 4.3-tahoe) for Vax
Makefile.4.3+NFS 4.3bsd+NFS from Wisconsin (Mt. Xinu?, others?)
Makefile.dec3100 DECStation 3100 + Ultrix 3.0 (incomplete)
Makefile.sun.2.0 Sun 4.2 UNIX Release 2.0 - 2.2 for Sun-2
Makefile.sun.3.0 Sun 4.2 UNIX Release 3.0 for Sun-2, Sun-3
Makefile.sun.3.2 Sun 4.2 UNIX Release 3.2 for Sun-2, Sun-3
Makefile.sun.4.0 SunOS 4.0 for Sun-2, Sun-3, Sun-4
Makefile.sun.4.0+386i SunOS 4.0 for Sun 386i
Makefile.sun.4.1 SunOS 4.1 for Sun-2, Sun-3, Sun-4
Makefile.sun4.3.2 SunOS Sys 4-3.2 for Sun-4
Makefile.ultrix.2.0 DEC Ultrix 2.0 - 2.2
Makefile.ultrix.3.0 DEC Ultrix 3.0
(I also have a somewhat ancient implementation for V7 on a PDP-11 as well
as Unisoft Version 1.3 on a MC68000 if anyone is interested).

XIntroduction:
X SPS is a intended to be used as a replacement for the standard
X ps(1) program. Its advantages over ps(1) are that it shows more
X useful information, that the displayed information is more
X comprehensible and that it is faster.
X

X (I also have a somewhat ancient implementation for V7 on a PDP-11 as well
X as Unisoft Version 1.3 on a MC68000 if anyone is interested).
X
X
XWhat SPS does:
X SPS displays wait channels symbolically, rather than as hexadecimal
X addresses. (If you wish to teach SPS about a new sort of device,
X you must add an entry in the symbol table (globals2.c) as well as
X increasing the size of that table (NWAITSTATE in sps.h)).
X
X SPS sorts processes before listing them, the order reflecting the
X relationship of the processes. A child process is listed
X underneath its corresponding parent and is indented to depict the
X exact relationship. SPS also indicates setuid processes.
X
X SPS displays such values as the resident and virtual sizes of
X system processes. It accepts a whole range of options to control
X the output. By default, SPS lists information about one's own
X processes. Other options instruct it to be verbose (the "v"
X option), to list all the command arguments of a process (the "w"
X option) or to list the environment strings of that process (the "e"
X option). Similarly, there are options to control which processes
X are to be displayed. The "a" option tells it to describe all
X processes and the "b" option tells it to describe "busy" processes;
X the latter is useful if you wish to find out what is loading your
X system. There are also options to select the output according to
X user, controlling tty or process number.
X
X SPS keeps its information in an information file; by default, this
X is /tmp/.spsinfo. This means that it can avoid having to do an
X expensive nlist() operation each time it is run. It must be
X reinitialised (with the "i" option) if new users are added to
X /etc/passwd or if a new version of /vmunix is installed.
X
X
XHow to build SPS:
X 1. In order to compile and install SPS, first unbundle the four shell
X archive files.
X 2. Check that the define statements in sps.h are large enough for
X your system. In particular, you may need to increase MAXTTYS
X to reflect the number of tty devices in /dev. The parameter
X MAXUSERS defines the maximum number of users defined in the
X password file (or through the Yellow Pages). Because the
X user-ids are held in an internal hash table, this should
X probably be at least double the number of actual users.
X 3. Choose an appropriate Makefile from the table above and compile
X the source files. For example:
X % make -f Makefile.sun.3.2
X 4. Try running SPS. First, a suitable information file must be
X initialised. It should then be able to display information
X concerning running processes on your system:
X # Initialise SPS. Ignore any error messages at this stage.
X % sps i
X # Instruct SPS to list all active processes in verbose format.
X % sps va
X 5. If this all works, install SPS with the appropriate Makefile
X and reinitialise it:
X % make -f Makefile.sun.3.2 install
X % sps -i

X.SH NAME
Xsps \ \ \-\ \ \ show process status
X.SH SYNOPSIS
X\fBsps\ \fP \ [ \fB\-cdefgijkoqrslvwyABDFNPSTUWZ\fP ]\ \ [
X\fIprocess\ .\ .\ .\ | tty\ .\ .\ .\ | user\ .\ .\ .\fP ]
X.SH DESCRIPTION
X\fISps\fP reports information concerning system processes.
XIt shows the current state of any process by
Xlisting information such as ownership, CPU time usage, memory usage
Xand disc activity.
X.PP
X\fISps\fP should be used in preference to \fIps\fP(1)
Xbecause it is faster and the output is more comprehensive and more
Xcomprehensible.
X.SH OPTIONS
XBy default, \fIsps\fP prints basic information about one's own processes.
XThe various options described below select other processes or make
X\fIsps\fP more verbose.
X.PP
XUpper case options select processes to be described.
XLower case options specify the format of the output.
XFor instance, the options \fBBv\fP specify that \fIsps\fP
Xshould list ``busy'' processes in a verbose format.
XUnless there is any conflict, lower case options may be used
Xinstead of upper case options, and vice versa.
X.PP
XThe following options specify the format of the listed output \-
X.TP 8
X\fB\-c\fP
XUse the system's idea of the command, rather than getting the arguments
Xfrom user space. While somewhat less informative, this is faster and
Xmore reliable.
X.TP
X\fB\-d\fP
XList output reflecting how each process affects the
Xdisc and paging activity of the system.
X.TP
X\fB\-e\fP
XList the environment passed to each process.
X.TP
X\fB\-f\fP
XInclude the process\-id of the parent of each process.
X.TP
X\fB\-g\fP
XInclude the process group of each process.
X.TP
X\fB\-o\fP
XAvoid looking at the swap device (\fB/dev/drum\fP). This tends to make \fIsps\fP
Xrun faster, although no information concerning swapped processes
Xcan be obtained.
X.TP
X\fB\-q\fP
XBy default, \fIsps\fP
Xlists the sum of the user plus system times under the
X\fITime\fP and \fIChild\fP fields. This option forces \fIsps\fP
Xto list only the user times.
X.TP
X\fB\-r\fP
XRepeat the output indefinitely.
XIf the next argument is numeric, \fIsps\fP repeats the output with that
Xmany seconds delay between each repetition.
XOtherwise the output is repeated with no delay.
X.TP
X\fB\-l\fP
X.br
X.ns
X.TP
X\fB\-v\fP
XList additional information in a verbose format. See below.
X.TP
X\fB\-w\fP
XList output in a wide format. This option forces \fIsps\fP
Xto print all the command arguments, even if doing so extends the output
Xbeyond one line.
X.TP
X\fB\-y\fP
XShow the status of each terminal line.
X.PP
XThe following options specify which processes are to be described \-
X.TP 8
X\fB\-A\fP
XList all processes.
X.TP
X\fB\-B\fP
XList busy processes. A process is considered to be busy
Xif it is immediately runnable or awaiting a fast event such as disc I/O.
X.TP
X\fB\-D\fP
XList detached processes.
X.TP
X\fB\-F\fP
XList foreground processes.
X.TP
X\fB\-N\fP
XShow no processes at all. Only the summary line is printed.
X.TP
X\fB\-P\fP
XList only processes whose identifiers are specified in the following arguments.
X.TP
X\fB\-S\fP
XList stopped processes.
X.TP
X\fB\-T\fP
XList only processes attached to the following specified terminals.
X.TP
X\fB\-U\fP
XList only processes belonging to the following specified users.
X.TP
X\fB\-W\fP
XList waiting processes.
X.TP
X\fB\-Z\fP
XList zomby (exiting) processes.
X.PP
XThe following are miscellaneous options \-
X.TP 8
X\fB\-i\fP
XInitialise \fIsps\fP.
XThis is necessary if new users are added to the password file,
Xor if a new version of UNIX is installed.
XSps builds a new information file summarising pertinent information
Xread from the password file (\fB/etc/passwd\fP), the executable kernel image
X(\fB/vmunix\fP) and the directory of tty devices (\fB/dev\fP).
XSee also the \fB\-j\fP and \fB\-s\fP options.
X.TP
X\fB\-j\fP
XSpecify an information file other than the default (\fB/etc/spsinfo\fP).
XThe next argument is taken to be the name of a suitable information file.
XIf the \fB\-i\fP flag is also specified, \fIsps\fP builds a
Xnew information file with the given name.
XOtherwise, \fBsps\fP reads previously created summarising information
Xfrom that file.
X.TP
X\fB\-k\fP
XUse a specific disc file rather than the default physical
Xmemory (\fB/dev/mem\fP)
Xand kernel virtual memory (\fB/dev/kmem\fP) files. The next argument is taken
Xto be the name of a suitable memory dump file.
XThis flag automatically sets the \fB\-o\fP flag.
X.TP
X\fB\-s\fP
XThis option is used in conjunction with the \fB\-i\fP option.
XThe next argument is taken to be the name of a suitable kernel executable
Xfile, rather than the default (\fB/vmunix\fP).
X\fISps\fP looks at the symbol table of this file to determine
Xthe virtual addresses of various kernel structures.
X.SH OUTPUT
X\fISps\fP produces output in the following fields \-
X.TP 8
X\fITy\fP
XThe terminal identifier to which the process is attached.
X.IP
XIf this is followed by an underscore, the process is detached.
XIf it is followed by a period, the process is running in the foreground.
XOtherwise the process is running in the background but is still
Xattached to a terminal.
X.TP
X\fIUser\fP
XThe symbolic name of the process' effective user-id (see \fIexec\fP(2)
Xand \fIsetuid\fP(2)).
XThis name is defined by the system password file (\fB/etc/passwd\fP)
Xwhen \fIsps\fP was last initialised.
XOtherwise, an asterisk (\fB*\fP) or vertical bar (\fB|\fP) appearing in this
Xcolumn denotes that the process is an immediate relative of the
Xpreceding process.
XA bar is listed, rather than an asterisk, if both processes belong
Xto the same process group.
XA user name is listed only if the effective user-id
Xdiffers from that of the preceding process or if it is a top-level
Xprocess (immediate offspring of process 1).
X.TP
X\fIProc#\fP
XThe unique process identifier.
X.TP
X\fIPpid#\fP
XThe process-id of the process' parent.
X.TP
X\fIPgrp#\fP
XThe process group to which the process belongs.
X.TP
X\fICommand\fP
XThe command arguments obtained from the process' own address space.
X(If the command name appears in parentheses, \fIsps\fP
Xwas unable to locate the arguments in user space and so reports
Xthe system's idea of the command name.)
X.PP
XThe following additional fields are listed when \fIsps\fP
Xis invoked with one of the \fB\-l\fP or \fB\-v\fP options \-
X.TP 8
X\fIStatus\fP
XThe process' current state.
XIf this field is listed in upper-case letters, the process is currently
Xloaded in real memory space ; otherwise it has been swapped out.
XThe status field may contain one of the following descriptions \-
X.RS 8
X.TP 16
X\fIrun\fP
XThe process can be run immediately.
X.TP
X\fIstop\fP
XThe process is stopped. See \fIsigvec\fP(2).
X.TP
X\fIexit\fP
XThe process is a zomby.
X.RE
X.IP
XAny other entry in the status field indicates the process is
Xwaiting for some external event to occur.
XThis is usually for one of the reasons listed below.
X(If \fIsps\fP does not know why a process is waiting, it lists
Xthe hexadecimal address of the process' wait channel,
Xwith the initial 80000000 trimmed off.)
XA process may be waiting for one of the following reasons \-
X.RS 8
X.TP 16
X\fIchild\fP
XThe process is waiting for a child to terminate. See \fIwait\fP(2).

X.TP
X\fIrswbuf\fP
XWaiting for a read from the swap device \fB/dev/drum.\fP
X.TP
X\fIdiscio\fP
XWaiting for a disc read or write operation.
X(Actually, this means that the process is waiting for an operation
Xthrough the kernel's I/O buffering mechanism to complete, but \fIdiscio\fP
Xis what is generally meant here).
X.TP
X\fIrpipe\fP
X.br
X.ns

Xand the number and real size of swapped processes.
X.SH DIAGNOSTICS
X\fISps\fP reports a self-explanatory message if it is given an
Xinvalid argument list.
XThe program also complains if it cannot find necessary system information.
X.PP
XAt initialisation, \fIsps\fP complains if it cannot find the addresses of
Xrequisite system structures in the kernel symbol file.
XThis is usually the case because the system is rarely configured to support
Xall known devices.
X\fISps\fP also complains if more than one user shares the same user-id
Xin the password file (\fB/etc/passwd\fP).

X.SH BUGS
XBecause the system is continually changing, the information reported by
X\fIsps\fP is only an approximation to reality.
XIf invoked by root, \fIsps\fP renices itself to \-20 in an attempt to run as
Xfast as possible.
X.PP
X\fISps\fP recognises the sizes and addresses of internal kernel
Xtables whenever it is invoked. However, it must be recompiled
Xif major modifications are made to the kernel.
X.PP
X\fISps\fP does not list all the detailed information shown by \fIps\fP(1).
XNor are all the options supported by \fIps\fP(1) available from \fIsps\fP.
X.PP
X\fISps\fP does not understand all the possible
Xreasons why a process may be sleeping.
X.PP
XThe code of \fIsps\fP is inherently machine-dependent and non-portable.
X.PP
XThe number of options to \fIsps\fP is ridiculous.
