I3STATUS(1)                        i3 Manual                       I3STATUS(1)

       i3status - Generates a status line for i3bar, dzen2, xmobar or lemonbar

       i3status [-c configfile] [-h] [-v]

           Specifies an alternate configuration file path. By default,
           i3status looks for configuration files in the following order:

            1. ~/.config/i3status/config (or $XDG_CONFIG_HOME/i3status/config
               if set)

            2. /etc/xdg/i3status/config (or $XDG_CONFIG_DIRS/i3status/config
               if set)

            3. ~/.i3status.conf

            4. /etc/i3status.conf

       i3status is a small program for generating a status bar for i3bar,
       dzen2, xmobar, lemonbar or similar programs. It is designed to be very
       efficient by issuing a very small number of system calls, as one
       generally wants to update such a status line every second. This ensures
       that even under high load, your status bar is updated correctly. Also,
       it saves a bit of energy by not hogging your CPU as much as spawning
       the corresponding amount of shell commands would.

       The basic idea of i3status is that you can specify which "modules"
       should be used (the order directive). You can then configure each
       module with its own section. For every module, you can specify the
       output format. See below for a complete reference.

       Sample configuration.

           general {
                   output_format = "dzen2"
                   colors = true
                   interval = 5

           order += "ipv6"
           order += "disk /"
           order += "run_watch DHCP"
           order += "run_watch VPNC"
           order += "path_exists VPN"
           order += "wireless wlan0"
           order += "ethernet eth0"
           order += "battery 0"
           order += "cpu_temperature 0"
           order += "memory"
           order += "load"
           order += "tztime local"
           order += "tztime berlin"

           wireless wlan0 {
                   format_up = "W: (%quality at %essid, %bitrate) %ip"
                   format_down = "W: down"

           ethernet eth0 {
                   format_up = "E: %ip (%speed)"
                   format_down = "E: down"

           battery 0 {
                   format = "%status %percentage %remaining %emptytime"
                   format_down = "No battery"
                   status_chr = "â¡ CHR"
                   status_bat = "ð BAT"
                   status_unk = "? UNK"
                   status_full = "â» FULL"
                   path = "/sys/class/power_supply/BAT%d/uevent"
                   low_threshold = 10

           run_watch DHCP {
                   pidfile = "/var/run/dhclient*.pid"

           run_watch VPNC {
                   # file containing the PID of a vpnc process
                   pidfile = "/var/run/vpnc/pid"

           path_exists VPN {
                   # path exists when a VPN tunnel launched by nmcli/nm-applet is active
                   path = "/proc/sys/net/ipv4/conf/tun0"

           tztime local {
                   format = "%Y-%m-%d %H:%M:%S"
                   hide_if_equals_localtime = true

           tztime berlin {
                   format = "%Y-%m-%d %H:%M:%S %Z"
                   timezone = "Europe/Berlin"

           load {
                   format = "%5min"

           cpu_temperature 0 {
                   format = "T: %degrees °C"
                   path = "/sys/devices/platform/coretemp.0/temp1_input"

           memory {
                   format = "%used"
                   threshold_degraded = "10%"
                   format_degraded = "MEMORY: %free"

           disk "/" {
                   format = "%free"

           read_file uptime {
                   path = "/proc/uptime"

       The colors directive will disable all colors if you set it to false.
       You can also specify the colors that will be used to display "good",
       "degraded" or "bad" values using the color_good, color_degraded or
       color_bad directives, respectively. Those directives are only used if
       color support is not disabled by the colors directive. The input format
       for color values is the canonical RGB hexadecimal triplet (with no
       separators between the colors), prefixed by a hash character ("#").

       Example configuration:

           color_good = "#00FF00"

       Likewise, you can use the color_separator directive to specify the
       color that will be used to paint the separator bar. The separator is
       always output in color, even when colors are disabled by the colors
       directive. This option has no effect when output_format is set to i3bar
       or none.

       The interval directive specifies the time in seconds for which i3status
       will sleep before printing the next status line.

       Using output_format you can choose which format strings i3status should
       use in its output. Currently available are:

           i3bar comes with i3 and provides a workspace bar which does the
           right thing in multi-monitor situations. It also comes with tray
           support and can display the i3status output. This output type uses
           JSON to pass as much meta-information to i3bar as possible (like
           colors, which blocks can be shortened in which way, etc.).

           Dzen is a general purpose messaging, notification and menuing
           program for X11. It was designed to be scriptable in any language
           and integrate well with window managers like dwm, wmii and xmonad
           though it will work with any window manager

           xmobar is a minimalistic, text based, status bar. It was designed
           to work with the xmonad Window Manager.

           lemonbar is a lightweight bar based entirely on XCB. It has full
           UTF-8 support and is EWMH compliant.

           Use ANSI Escape sequences to produce a terminal-output as close as
           possible to the graphical outputs. This makes debugging your config
           file a little bit easier because the terminal-output of i3status
           becomes much more readable, but should only used for such quick
           glances, because it will only support very basic output-features
           (for example you only get 3 bits of color depth).

           Does not use any color codes. Separates values by the pipe symbol
           by default. This should be used with i3bar and can be used for
           custom scripts.

       It’s also possible to use the color_good, color_degraded, color_bad
       directives to define specific colors per module. If one of these
       directives is defined in a module section its value will override the
       value defined in the general section just for this module.

       If you don’t fancy the vertical separators between modules
       i3status/i3bar uses by default, you can employ the separator directive
       to configure how modules are separated. You can also disable the
       default separator altogether by setting it to the empty string. You
       might then define separation as part of a module’s format string. This
       is your only option when using the i3bar output format as the separator
       is drawn by i3bar directly otherwise. For the other output formats, the
       provided non-empty string will be automatically enclosed with the
       necessary coloring bits if color support is enabled.

       i3bar supports Pango markup, allowing your format strings to specify
       font, color, size, etc. by setting the markup directive to "pango".
       Note that the ampersand ("&"), less-than ("<"), greater-than (">"),
       single-quote ("'"), and double-quote (""") characters need to be
       replaced with "&amp;", "&lt;", "&gt;", "&apos;", and "&quot;"
       respectively. This is done automatically for generated content (e.g.
       wireless ESSID, time).

       Example configuration:

           general {
               output_format = "xmobar"
               separator = "  "

           order += "load"
           order += "disk /"

           load {
               format = "[ load: %1min, %5min, %15min ]"
           disk "/" {
               format = "%avail"

       This module gets the IPv6 address used for outgoing connections (that
       is, the best available public IPv6 address on your computer).

       Example format_up: %ip

       Example format_down: no IPv6

       Gets used, free, available and total amount of bytes on the given
       mounted filesystem.

       These values can also be expressed in percentages with the
       percentage_used, percentage_free, percentage_avail and
       percentage_used_of_avail formats.

       Byte sizes are presented in a human readable format using a set of
       prefixes whose type can be specified via the "prefix_type" option.
       Three sets of prefixes are available:

           IEC prefixes (Ki, Mi, Gi, Ti) represent multiples of powers of
           1024. This is the default.

           SI prefixes (k, M, G, T) represent multiples of powers of 1000.

           The custom prefixes (K, M, G, T) represent multiples of powers of

       It is possible to define a low_threshold that causes the disk text to
       be displayed using color_bad. The low_threshold type can be of
       threshold_type "bytes_free", "bytes_avail", "percentage_free", or
       "percentage_avail", where the former two can be prepended by a generic
       prefix (k, m, g, t) having prefix_type. So, if you configure
       low_threshold to 2, threshold_type to "gbytes_avail", and prefix_type
       to "binary", and the remaining available disk space is below 2 GiB, it
       will be colored bad. If not specified, threshold_type is assumed to be
       "percentage_avail" and low_threshold to be set to 0, which implies no
       coloring at all. You can customize the output format when below
       low_threshold with format_below_threshold.

       You can define a different format with the option "format_not_mounted"
       which is used if the path does not exist or is not a mount point.
       Defaults to "".

       Example order: disk /mnt/usbstick

       Example format: %free (%avail)/ %total

       Example format: %percentage_used used, %percentage_free free,
       %percentage_avail avail

       Example prefix_type: custom

       Example low_threshold: 5

       Example format_below_threshold: Warning: %percentage_avail

       Example threshold_type: percentage_free

       Expands the given path to a pidfile and checks if the process ID found
       inside is valid (that is, if the process is running). You can use this
       to check if a specific application, such as a VPN client or your DHCP
       client is running. There also is an option "format_down". You can hide
       the output with format_down="".

       Example order: run_watch DHCP

       Example format: %title: %status

       Checks if the given path exists in the filesystem. You can use this to
       check if something is active, like for example a VPN tunnel managed by
       NetworkManager. There also is an option "format_down". You can hide the
       output with format_down="".

       Example order: path_exists VPN

       Example format: %title: %status

       Gets the link quality, frequency and ESSID of the given wireless
       network interface. You can specify different format strings for the
       network being connected or not connected. The quality is padded with
       leading zeroes by default; to pad with something else use

       The special interface name _first_ will be replaced by the first
       wireless network interface found on the system (excluding devices
       starting with "lo").

       Example order: wireless wlan0

       Example format_up: W: (%quality at %essid, %bitrate / %frequency) %ip

       Example format_down: W: down

       Example format_quality: "%03d%s"

       Gets the IP address and (if possible) the link speed of the given
       ethernet interface. If no IPv4 address is available and an IPv6 address
       is, it will be displayed.

       The special interface name _first_ will be replaced by the first
       non-wireless network interface found on the system (excluding devices
       starting with "lo").

       Example order: ethernet eth0

       Example format_up: E: %ip (%speed)

       Example format_down: E: down

       Gets the status (charging, discharging, unknown, full), percentage,
       remaining time and power consumption (in Watts) of the given battery
       and when it’s estimated to be empty. If you want to use the last full
       capacity instead of the design capacity (when using the design
       capacity, it may happen that your battery is at 23% when fully charged
       because it’s old. In general, I want to see it this way, because it
       tells me how worn off my battery is.), just specify last_full_capacity
       = true. You can show seconds in the remaining time and empty time
       estimations by setting hide_seconds = false.

       If you want the battery percentage to be shown without decimals, add
       integer_battery_capacity = true.

       If your battery is represented in a non-standard path in /sys, be sure
       to modify the "path" property accordingly, i.e. pointing to the uevent
       file on your system. The first occurrence of %d gets replaced with the
       battery number, but you can just hard-code a path as well.

       It is possible to define a low_threshold that causes the battery text
       to be colored red. The low_threshold type can be of threshold_type
       "time" or "percentage". So, if you configure low_threshold to 10 and
       threshold_type to "time", and your battery lasts another 9 minutes, it
       will be colored red.

       To show an aggregate of all batteries in the system, use "all" as the
       number. In this case (for Linux), the /sys path must contain the "%d"
       sequence. Otherwise, the number indicates the battery index as reported
       in /sys.

       Optionally custom strings including any UTF-8 symbols can be used for
       different battery states. This makes it possible to display individual
       symbols for each state (charging, discharging, unknown, full) Of course
       it will also work with special iconic fonts, such as FontAwesome. If
       any of these special status strings are omitted, the default (CHR, BAT,
       UNK, FULL) is used.

       Example order (for the first battery): battery 0

       Example order (aggregate of all batteries): battery all

       Example format: %status %remaining (%emptytime %consumption)

       Example format_down: No battery

       Example status_chr: â¡ CHR

       Example status_bat: ð BAT

       Example status_unk: ? UNK

       Example status_full: â» FULL

       Example low_threshold: 30

       Example threshold_type: time

       Example path (%d replaced by title number):

       Example path (ignoring the number): /sys/class/power_supply/CMB1/uevent

       Gets the temperature of the given thermal zone. It is possible to
       define a max_threshold that will color the temperature red in case the
       specified thermal zone is getting too hot. Defaults to 75 degrees C.
       The output format when above max_threshold can be customized with

       Example order: cpu_temperature 0

       Example format: T: %degrees °C

       Example max_threshold: 42

       Example format_above_threshold: Warning T above threshold: %degrees °C

       Example path: /sys/devices/platform/coretemp.0/temp1_input

   CPU Usage
       Gets the percentual CPU usage from /proc/stat (Linux) or sysctl(3)

       It is possible to define a max_threshold that will color the load value
       red in case the CPU average over the last interval is getting higher
       than the configured threshold. Defaults to 95. The output format when
       above max_threshold can be customized with format_above_threshold.

       It is possible to define a degraded_threshold that will color the load
       value yellow in case the CPU average over the last interval is getting
       higher than the configured threshold. Defaults to 90. The output format
       when above degraded threshold can be customized with

       For displaying the Nth CPU usage, you can use the %cpu<N> format
       string, starting from %cpu0. This feature is currently not supported in

       Example order: cpu_usage

       Example format: all: %usage CPU_0: %cpu0 CPU_1: %cpu1

       Example max_threshold: 75

       Example format_above_threshold: Warning above threshold: %usage

       Example degraded_threshold: 25

       Example format_above_degraded_threshold: Warning above degraded
       threshold: %usage

       Gets the memory usage from system on a Linux system from /proc/meminfo.
       Other systems are currently not supported.

       As format placeholders, total, used, free, available and shared are
       available. These will print human readable values. It’s also possible
       to prefix the placeholders with percentage_ to get a value in percent.

       It’s possible to define a threshold_degraded and a threshold_critical
       to color the status bar output in yellow or red, if the available
       memory falls below the given threshold. Possible values of the
       threshold can be any integer, suffixed with an iec symbol (T, G, M, K).
       Alternatively, the integer can be suffixed by a percent sign, which
       then rets evaluated relatively to total memory.

       If the format_degraded parameter is given and either the critical or
       the degraded threshold applies, format_degraded will get used as format
       string. It acts equivalently to format.

       As Linux' meminfo doesn’t expose the overall memory in use, there are
       multiple methods to distinguish the actually used memory.

       Example memory_used_method: memavailable ("total memory" -
       "MemAvailable", matches free command)

       Example memory_used_method: classical ("total memory" - "free" -
       "buffers" - "cache", matches gnome system monitor)

       Example order: memory

       Example format: %free %available (%used) / %total

       Example format: %percentage_used used, %percentage_free free,
       %percentage_shared shared

       Example threshold_degraded: 10%

       Example threshold_critical: 5%

       Example format_degraded: Memory LOW: %free

       Gets the system load (number of processes waiting for CPU time in the
       last 1, 5 and 15 minutes). It is possible to define a max_threshold
       that will color the load value red in case the load average of the last
       minute is getting higher than the configured threshold. Defaults to 5.
       The output format when above max_threshold can be customized with

       Example order: load

       Example format: %1min %5min %15min

       Example max_threshold: "0.1"

       Example format_above_threshold: Warning: %1min %5min %15min

       Outputs the current time in the local timezone. To use a different
       timezone, you can set the TZ environment variable, or use the tztime
       module. See strftime(3) for details on the format string.

       Example order: time

       Example format: %Y-%m-%d %H:%M:%S

       Outputs the current time in the given timezone. If no timezone is
       given, local time will be used. See strftime(3) for details on the
       format string. The system’s timezone database is usually installed in
       /usr/share/zoneinfo. Files below that path make for valid timezone
       strings, e.g. for /usr/share/zoneinfo/Europe/Berlin you can set
       timezone to Europe/Berlin in the tztime module. To override the locale
       settings of your environment, set the locale option. To display time
       only when the set timezone has different time from localtime, set
       hide_if_equals_localtime to true.

       Example order: tztime berlin

       Example format: %Y-%m-%d %H:%M:%S %Z

       Example timezone: Europe/Berlin

       Example locale: de_DE.UTF-8

       If you would like to use markup in this section, there is a separate
       format_time option that is automatically escaped. Its output then
       replaces %time in the format string.

       Example configuration (markup):

           tztime berlin {
                   format = "<span foreground='#ffffff'>time:</span> %time"
                   format_time = "%H:%M %Z"
                   timezone = "Europe/Berlin"
                   hide_if_equals_localtime = true

       Outputs the current discordian date in user-specified format. See
       ddate(1) for details on the format string. Note: Neither %. nor %X are
       implemented yet.

       Example order: ddate

       Example format: %{%a, %b %d%}, %Y%N - %H

       Outputs the volume of the specified mixer on the specified device.
       PulseAudio and ALSA (Linux only) are supported. If PulseAudio is
       absent, a simplified configuration can be used on FreeBSD and OpenBSD
       due to the lack of ALSA, the device and mixer options can be ignored on
       these systems. On these systems the OSS API is used instead to query
       /dev/mixer directly if mixer_idx is -1, otherwise

       To get PulseAudio volume information, one must use the following format
       in the device line:

           device = "pulse"


           device = "pulse:N"

       where N is the index or name of the PulseAudio sink. You can obtain the
       name of the sink with the following command:

           $ pacmd list-sinks | grep name:
                      name: <alsa_output.pci-0000_00_14.2.analog-stereo>

       The name is what’s inside the angle brackets, not including them. If no
       sink is specified the default sink is used. If the device string is
       missing or is set to "default", PulseAudio will be tried if detected
       and will fallback to ALSA (Linux) or OSS (FreeBSD/OpenBSD).

       Example order: volume master

       Example format: ⪠(%devicename): %volume

       Example format_muted: ⪠(%devicename): 0%%

       Example configuration:

           volume master {
                   format = "âª: %volume"
                   format_muted = "âª: muted (%volume)"
                   device = "default"
                   mixer = "Master"
                   mixer_idx = 0

       Example configuration (PulseAudio):

           volume master {
                   format = "âª: %volume"
                   format_muted = "âª: muted (%volume)"
                   device = "pulse:1"

           volume master {
                   format = "âª: %volume"
                   format_muted = "âª: muted (%volume)"
                   device = "pulse:alsa_output.pci-0000_00_14.2.analog-stereo"

   File Contents
       Outputs the contents of the specified file. You can use this to check
       contents of files on your system, for example /proc/uptime. By default
       the function only reads the first 254 characters of the file, if you
       want to override this set the Max_characters option. It will never read
       beyond the first 4095 characters. If the file is not found "no file"
       will be printed, if the file can’t be read "error read" will be

       Example order: read_file UPTIME

       Example format: "%title: %content"

       Example format_bad: "%title - %errno: %error"

       Example path: "/proc/uptime"

       Example Max_characters: 255

       When using the i3bar output format, there are a few additional options
       that can be used with all modules to customize their appearance:

           The alignment policy to use when the minimum width (see below) is
           not reached. Either center (default), right or left.

           The minimum width (in pixels) the module should occupy. If the
           module takes less space than the specified size, the block will be
           padded to the left and/or the right side, according to the defined
           alignment policy. This is useful when you want to prevent the whole
           status line from shifting when values take more or less space
           between each iteration. The option can also be a string. In this
           case, the width of the given text determines the minimum width of
           the block. This is useful when you want to set a sensible minimum
           width regardless of which font you are using, and at what
           particular size. Please note that a number enclosed with quotes
           will still be treated as a number.

           A boolean value which specifies whether a separator line should be
           drawn after this block. The default is true, meaning the separator
           line will be drawn. Note that if you disable the separator line,
           there will still be a gap after the block, unless you also use

           The amount of pixels to leave blank after the block. In the middle
           of this gap, a separator symbol will be drawn unless separator is
           disabled. This is why the specified width should leave enough space
           for the separator symbol.

       Example configuration:

           disk "/" {
               format = "%avail"
               align = "left"
               min_width = 100
               separator = false
               separator_block_width = 1

       After installing dzen2, you can directly use it with i3status. Just
       ensure that output_format is set to dzen2. Note: min_width is not

       Example for usage of i3status with dzen2:

           i3status | dzen2 -fg white -ta r -w 1280 \
           -fn "-misc-fixed-medium-r-normal--13-120-75-75-C-70-iso8859-1"

       To get xmobar to start, you might need to copy the default
       configuration file to ~/.xmobarrc. Also, ensure that the output_format
       option for i3status is set to xmobar. Note: min_width is not supported.

       Example for usage of i3status with xmobar:

           i3status | xmobar -o -t "%StdinReader%" -c "[Run StdinReader]"

       While talking about specific things, please understand this section as
       a general explanation why your favorite information is not included in

       Let’s talk about CPU frequency specifically. Many people don’t
       understand how frequency scaling works precisely. The generally
       recommended CPU frequency governor ("ondemand") changes the CPU
       frequency far more often than i3status could display it. The display
       number is therefore often incorrect and doesn’t tell you anything
       useful either.

       In general, i3status wants to display things which you would look at
       occasionally anyways, like the current date/time, whether you are
       connected to a WiFi network or not, and if you have enough disk space
       to fit that 4.3 GiB download.

       However, if you need to look at some kind of information more than once
       in a while, you are probably better off with a script doing that, which
       pops up. After all, the point of computers is not to burden you with
       additional boring tasks like repeatedly checking a number.

       In i3status, we don’t want to implement process management again.
       Therefore, there is no module to run arbitrary scripts or commands.
       Instead, you should use your shell, for example like this:

       Example for prepending the i3status output:

           # shell script to prepend i3status with more stuff

           i3status | while :
                   read line
                   echo "mystuff | $line" || exit 1

       Put that in some script, say .bin/my_i3status.sh and execute that
       instead of i3status.

       Note that if you want to use the JSON output format (with colors in
       i3bar), you need to use a slightly more complex wrapper script. There
       are examples in the contrib/ folder, see

       When receiving SIGUSR1, i3status’s nanosleep() will be interrupted and
       thus you will force an update. You can use killall -USR1 i3status to
       force an update after changing the system volume, for example.
