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\fIpause\fP XWaiting for a signal to be received. See \fIsigpause\fP(2). X.TP X\fIswap\fP XWaiting for a page to be swapped in. 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 X.TP X\fIwpipe\fP XWaiting for a read from an empty pipe. Alternatively, the process Xis waiting to write to a full pipe. See \fIpipe\fP(2).

X.TP X\fIT\fP XThe process is being traced or debugged. X.TP X\fIV\fP XThe process is a child currently being vforked. See \fIvfork\fP(2). X.TP X\fII\fP XThe process is undergoing physical I/O. X.TP X\fIA\fP XThe system has detected, or the user has warned of Xanomalous paging behaviour. See \fIvadvise\fP(2). X.RE X.TP 8 X\fINice\fP XThe ``niceness'' of the process. See \fInice\fP(2). X.TP X\fIVirtual\fP XThe virtual memory size of the process in kilobytes. XThe first figure indicates the sum of the data and stack segments, Xthe second figure that of the text segment. X.TP X\fIResident\fP XThe resident memory size of the process in kilobytes, representing Xthe real memory devoted to the process. X.TP X\fI%M\fP XThe percentage of available real memory allocated to this process. X.TP X\fITime\fP XThe total CPU time accumulated by this process. X(This is the sum of the system plus user times, unless the \fB\-q\fP Xflag is specified in which case only the user time is listed.) X.TP X\fIChild\fP XThe total CPU time accumulated by the process' children. X(This is the sum of the system plus user times, unless the \fB\-q\fP Xflag is specified.) X.TP X\fI%C\fP XThe percentage of available CPU time devoted to the process. XThis figure is a decaying average, computed over the past second. X.PP XThe following fields are listed when \fIsps\fP is invoked with the X\fB\-d\fP option \- X.TP 8 X\fIFiles\fP XThe number of open files for this process. X.TP X\fIPageFaults\fP XThe number of major and minor page faults incurred by the process. X.TP X\fISwap\fP XThe number of swaps incurred by the process. X.TP X\fIBlockI/O\fP XThe number of block read or write operations performed Xon behalf of the process. X.TP X\fIKbytesecs\fP XThe integral of real memory usage over time. XThus, if a process uses 60 kilobytes of real memory for 3 seconds, Xthis figure is incremented by 180.

XThis indicates the number and total virtual memory size of all processes, Xthe number and total virtual size of busy processes, Xthe number and real memory size of loaded processes 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).
