General

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

dzen2

xmobar

lemonbar

term

none

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"
}

IPv6

Example format_up: %ip

Example format_down: no IPv6

Disk

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:

binary

decimal

custom

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

Run-watch

Example order: run_watch DHCP

Example format: %title: %status

Path-exists

Example order: path_exists VPN

Example format: %title: %status

Wireless

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_bitrate: "%g %cb/s"

Example format_noise: "%03d%s"

Example format_quality: "%03d%s"

Example format_signal: "%03d%s"

Ethernet

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

Battery

If you want the battery percentage to be shown in another format, use format_percentage. integer_battery_capacity = true is a legacy option for format_percentage = "%.00f%s"

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 color_bad. 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 color_bad.

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 format_percentage: "%.02f%s"

Example status_chr: ⚡ CHR

Example status_bat: 🔋 BAT

Example status_unk: ? UNK

Example status_full: ☻ FULL

Example low_threshold: 30

Example threshold_type: time

Example path (%d replaced by title number): /sys/class/power_supply/CMB%d/uevent

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

CPU-Temperature

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

It is possible to define a max_threshold that will color the load value with color_bad 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 with color_degraded 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 format_above_degraded_threshold.

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

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

Memory

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 color_degraded or color_bad, 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 gets 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.

It’s also possible to define the unit for the various format placeholders. As /proc/meminfo returns the memory in kB they will be converted to the given unit. If no unit is given or the auto option is used, the conversion will select the maximum possible unit.

As the converted format placeholder will be a decimal number, the number of decimals can be configured via the decimals option. If no such option is given the converted format placeholder will have one decimal.

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 unit: auto, Ki, Mi, Gi, Ti

Example decimals: 0, 1, 2, 3

Example threshold_degraded: 10%

Example threshold_critical: 5%

Example format_degraded: Memory LOW: %free

Load

Example order: load

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

Example max_threshold: "0.1"

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

Time

Example order: time

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

TzTime

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
}

DDate

Example order: ddate

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

Volume

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

device = "pulse"

or

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 = "♪: %volume"
        format_muted = "♪: muted (%volume)"
        device = "default"
        mixer = "Master"
        mixer_idx = 0
}

Example configuration (PulseAudio):

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

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

File Contents

Example order: read_file UPTIME

Example format: "%title: %content"

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

Example path: "/proc/uptime"

Example Max_characters: 255
