If +.I number +is given, then the top +.I number +processes will be displayed instead of the default. +.PP +.I Top +makes a distinction between terminals that support advanced capabilities +and those that do not. This +distinction affects the choice of defaults for certain options. In the +remainder of this document, an \*(lqintelligent\*(rq terminal is one that +supports cursor addressing, clear screen, and clear to end of line. +Conversely, a \*(lqdumb\*(rq terminal is one that does not support such +features. If the output of +.I top +is redirected to a file, it acts as if it were being run on a dumb +terminal. +.SH OPTIONS +.if \nL==0 Long options are not available on this system. +.TP +.B "\-C, \-\-color" +Turn off the use of color in the display. +.TP +.B "\-I, \-\-idle-procs" +Do not display idle processes. +By default, top displays both active and idle processes. +.TP +.B "\-S, \-\-system-procs" +Show system processes in the display. Normally, system processes such as +the pager and the swapper are not shown. This option makes them visible. +.TP +.B "\-T, \-\-tag-names" +List all available color tags and the current set of tests used for +color highlighting, then exit. +.TP +.B "\-a, \-\-all" +Show all processes for as long as possible. This is shorthand for +\*(lq-d all all\*(rq. This option is especially handy in batch mode. +.TP +.B "\-b, \-n, \-\-batch" +Use \*(lqbatch\*(rq mode. In this mode, all input from the terminal is +ignored. Interrupt characters (such as ^C and ^\e) still have an effect. +This is the default on a dumb terminal, or when the output is not a terminal. +.TP +.B "\-c, \-\-full-commands" +Show the full command line for each process. Default is to show just the +command name. This option is not supported on all platforms. +.TP +.B "\-i, \-\-interactive" +Use \*(lqinteractive\*(rq mode. In this mode, any input is immediately +read for processing. See the section on \*(lqInteractive Mode\*(rq +for an explanation of +which keys perform what functions. After the command is processed, the +screen will immediately be updated, even if the command was not +understood. This mode is the default when standard output is an +intelligent terminal. +.TP +.B "\-q, \-\-quick" +Renice +.I top +to -20 so that it will run faster. This can be used when the system is +being very sluggish to improve the possibility of discovering the problem. +This option can only be used by root. +.TP +.B "\-t, \-\-threads" +Show individual threads on separate lines. By default, on systems +which support threading, each process is shown with a count of the number +of threads. This option shows each thread on a separate line. This option +is not supported on all platforms. +.TP +.B "\-u, \-\-uids" +Do not take the time to map uid numbers to usernames. Normally, +.I top +will read as much of the file \*(lq/etc/passwd\*(rq as is necessary to map +all the user id numbers it encounters into login names. This option +disables all that, while possibly decreasing execution time. The uid +numbers are displayed instead of the names. +.TP +.B "\-v, \-\-version" +Write version number information to stderr then exit immediately. +No other processing takes place when this option is used. To see current +revision information while top is running, use the help command \*(lq?\*(rq. +.TP +.B "\-d \fIcount\fP, \-\-displays \fIcount\fP" +Show only +.I count +displays, then exit. A display is considered to be one update of the +screen. This option allows the user to select the number of displays he +wants to see before +.I top +automatically exits. Any proper prefix of the words \*(lqinfinity\*(rq, +\*(lqmaximum\*(rq, +or +\*(lqall\*(rq can be used to indicate an infinite number of displays. +The default for intelligent terminals is infinity. +The default for dumb terminals is 1. +.TP +.B "\-m \fImode\fP, \-\-mode=\fImode\fP" +Start the display in an alternate mode. Some platforms support multiple +process displays to show additional process information. The value +\fImode\fP is a number indicating which mode to display. The default is +0. On platforms that do not have multiple display modes this option has +no effect. +.TP +.B "\-o \fIfield\fP, \-\-sort-order=\fIfield\fP" +Sort the process display area on the specified field. The field name is +the name of the column as seen in the output, but in lower case. Likely +values are \*(lqcpu\*(rq, \*(lqsize\*(rq, \*(lqres\*(rq, and \*(lqtime\*(rq, +but may vary on different operating systems. Note that +not all operating systems support this option. +.TP +.B "\-s \fItime\fP, \-\-delay=\fItime\fP" +Set the delay between screen updates to +.I time +seconds. The default delay between updates is \nD seconds. +.TP +.B "\-U \fIusername\fP, \-\-user=\fIusername\fP" +Show only those processes owned by +.IR username . +This option currently only accepts usernames and will not understand +uid numbers. +.PP +Both +.I count +and +.I number +fields can be specified as \*(lqinfinite\*(rq, indicating that they can +stretch as far as possible. This is accomplished by using any proper +prefix of the keywords +\*(lqinfinity\*(rq, +\*(lqmaximum\*(rq, +or +\*(lqall\*(rq. +The default for +.I count +on an intelligent terminal is, in fact, +\fBinfinity\fP. +.PP +The environment variable +.B TOP +is examined for options before the command line is scanned. This enables +a user to set his or her own defaults. The number of processes to display +can also be specified in the environment variable +.BR TOP . +The options +.BR \-C , +.BR \-I , +.BR \-S , +and +.B \-u +are actually toggles. A second specification of any of these options +will negate the first. Thus a user who has the environment variable +.B TOP +set to \*(lq\-I\*(rq may use the command \*(lqtop \-I\*(rq to see idle processes. +.SH "INTERACTIVE MODE" +When +.I top +is running in \*(lqinteractive mode\*(rq, it reads commands from the +terminal and acts upon them accordingly. In this mode, the terminal is +put in \*(lqCBREAK\*(rq, so that a character will be +processed as soon as it is typed. Almost always, a key will be +pressed when +.I top +is between displays; that is, while it is waiting for +.I time +seconds to elapse. If this is the case, the command will be +processed and the display will be updated immediately thereafter +(reflecting any changes that the command may have specified). This +happens even if the command was incorrect. If a key is pressed while +.I top +is in the middle of updating the display, it will finish the update and +then process the command. Some commands require additional information, +and the user will be prompted accordingly. While typing this information +in, the user's erase and kill keys (as set up by the command +.IR stty ) +are recognized, and a newline terminates the input. Note that a control-L +(^L) always redraws the current screen and a space forces an immediate +update to the screen using new data. +.PP +These commands are currently recognized: +.TP +.I "\fBh\fP\ or\ \fB?\fP" +Display a summary of the commands (help screen). Version information +is included in this display. +.TP +.B C +Toggle the use of color in the display. +.TP +.B c +Display only processes whose commands match the specified string. An empty +string will display all processes. This command is not supported on all +platforms. +.TP +.B d +Change the number of displays to show (prompt for new number). +Remember that the next display counts as one, so typing +.B d1 +will make +.I top +show one final display and then immediately exit. +.TP +.B f +Toggle the display of the full command line. +.TP +.B H +Toggle the display of threads on separate lines. By default, on systems +which support threading, each process is shown with a count of the number +of threads. This command shows each thread on a separate line. This command +is not supported on all platforms. +.TP +.B i +(or +.BR I ) +Toggle the display of idle processes. +.if \nK==1 \{\ +.TP +.B k +Send a signal (\*(lqkill\*(rq by default) to a list of processes. This +acts similarly to the command +.IR kill (1)). +.\} +.TP +.B M +Sort display by memory usage. Shorthand for \*(lqo size\*(rq. +.TP +.B m +Change to a different process display mode. Some systems provide multiple +display modes for the process display which shows different information. +This command toggles between the available modes. This command is not +supported on all platforms. +.TP +.B N +Sort by process id. Shorthand for \*(lqo pid\*(rq. +.TP +.B n or # +Change the number of processes to display (prompt for new number). +.TP +.B o +Change the order in which the display is sorted. This command is not +available on all systems. The sort key names vary fron system to system +but usually include: \*(lqcpu\*(rq, \*(lqres\*(rq, \*(lqsize\*(rq, +\*(lqtime\*(rq. The default is cpu. +.TP +.B P +Sort by CPU usage. Shorthand for \*(lqo cpu\*(rq. +.TP +.B q +Quit +.IR top. +.if \nK==1 \{\ +.TP +.B r +Change the priority (the \*(lqnice\*(rq) of a list of processes. +This acts similarly to the command +.IR renice (8)). +.\} +.TP +.B s +Change the number of seconds to delay between displays +(prompt for new number). +.TP +.B T +Sort by CPU time. Shorthand for \*(lqo time\*(rq. +.TP +.B U +Toggle between displaying usernames and uids. +.TP +.B u +Display only processes owned by a specific username (prompt for username). +If the username specified is simply \*(lq+\*(rq, then processes belonging +to all users will be displayed. +.SH "THE DISPLAY" +The actual display varies depending on the specific variant of Unix +that the machine is running. This description may not exactly match +what is seen by top running on this particular machine. Differences +are listed at the end of this manual entry. +.PP +The top lines of the display show general information +about the state of the system. The first line shows +(on some systems) the last process id assigned to a process, +the three load averages, +the system uptime, and the current time. +The second line displays the total number of processes followed +by a breakdown of processes per state. Examples of states common +to Unix systems are sleeping, running, starting, stopped, and zombie. +The next line displays a percentage of time spent in each of the +processor states (typically user, nice, system, idle, and iowait). +These percentages show the processor activity during the time since +the last update. For multi-processor systems, this information is +a summation of time across all processors. The next line shows +kernel-related activity (not available on all systems). The numbers +shown on this line are per-second rates sampled since the last update. +The exact +information displayed varies between systems, but some examples are: +context switches, interrupts, traps, forks, and page faults. The last +one or two lines show a summary of memory and swap activity. These lines +vary between systems. +.PP +The remainder of the screen displays information about individual +processes. This display is similar in spirit to +.IR ps (1) +but it is not exactly the same. The columns displayed by top will +differ slightly between operating systems. Generally, the following +fields are displayed: +.TP +.B PID +The process id. +.TP +.B USERNAME +Username of the process's owner (if +.B \-u +is specified, a UID column will be substituted for USERNAME). +.TP +.B THR +The number of threads in the processes (this column may also +be labeled NLWP). +.TP +.B PRI +Current priority of the process. +.TP +.B NICE +Nice amount in the range \-20 to 20, as established by the use of +the command +.IR nice . +.TP +.B SIZE +Total size of the process (text, data, and stack) given in kilobytes. +.TP +.B RES +Resident memory: current amount of process memory that resides in physical +memory, given in kilobytes. +.TP +.B STATE +Current state (typically one of \*(lqsleep\*(rq, +\*(lqrun\*(rq, \*(lqidl\*(rq, \*(lqzomb\*(rq, or \*(lqstop\*(rq). +.TP +.B TIME +Number of system and user cpu seconds that the process has used. +.TP +.B CPU +Percentage of available cpu time used by this process. +.TP +.B COMMAND +Name of the command that the process is currently running. +.SH COLOR +Top supports the use of ANSI color in its output. By default, color is +available but not used. The environment variable +.B TOPCOLORS +specifies colors to use and conditions for which they should be used. +At the present time, only numbers in the summay display area can be +colored. In a future version it will be possible to highlight numbers +in the process display area as well. The environment variable is the +only way to specify color: there is no equivalent command line option. +Note that the environment variable +.B TOPCOLOURS +is also understood. The British spelling takes precedence. The use of +color only works on terminals that understand and process ANSI color +escape sequences. +.PP +The environment variable is a sequence of color specifications, separated +by colons. Each specification takes the form tag=min,max#code where +.I tag +is the name of the value to check, +.I min +and +.I max +specify a range for the value, and +.I code +is an ANSI color code. Multiple color codes can be listed and separated +with semi-colons. A missing +.I min +implies the lowest possible value (usually 0) +and a missing +.I max +implies infinity. The comma must always be present. When specifying numbers +for load averages, they should be multiplied by 100. +For example, the specification +.B 1min=500,1000#31 +indicates that a 1 minute load average between +5 and 10 should be displayed in red. Color attributes can be combined. +For example, the specification +.B 5min=1000,#37;41 +indicates that a 5 minute load average higher than 10 should be displayed +with white characters on a red background. A special tag named +.I header +is used to control the color of the header for process display. It should +be specified with no lower and upper limits, specifically +.B header=,# +followed by the ANSI color code. +.PP +You can see a list of color codes recognized by this installation of top +with the +.B \-T +option. This will also show the current set of tests used for +color highligting, as specified in the environment. +.SH AUTHOR +William LeFebvre +.SH ENVIRONMENT +.DT +TOP user-configurable defaults for options. +TOPCOLORS color specification +.SH BUGS +As with +.IR ps (1), +things can change while +.I top +is collecting information for an update.
