QMK CLI Commands

User Commands

qmk compile

This command allows you to compile firmware from any directory. You can compile JSON exports from https://config.qmk.fm, compile keymaps in the repo, or compile the keyboard in the current working directory.

This command is directory aware. It will automatically fill in KEYBOARD and/or KEYMAP if you are in a keyboard or keymap directory.

Usage for Configurator Exports:

qmk compile [-c] <configuratorExport.json>

Usage for Keymaps:

qmk compile [-c] [-e <var>=<value>] [-j <num_jobs>] -kb <keyboard_name> -km <keymap_name>

Usage in Keyboard Directory:

Must be in keyboard directory with a default keymap, or in keymap directory for keyboard, or supply one with --keymap <keymap_name>

qmk compile

Usage for building all keyboards that support a specific keymap:

qmk compile -kb all -km <keymap_name>

Example:

$ qmk config compile.keymap=default
$ cd ~/qmk_firmware/keyboards/planck/rev6
$ qmk compile
Ψ Compiling keymap with make planck/rev6:default
...

or with optional keymap argument

$ cd ~/qmk_firmware/keyboards/clueboard/66/rev4
$ qmk compile -km 66_iso
Ψ Compiling keymap with make clueboard/66/rev4:66_iso
...

or in keymap directory

$ cd ~/qmk_firmware/keyboards/gh60/satan/keymaps/colemak
$ qmk compile
Ψ Compiling keymap with make gh60/satan:colemak
...

Usage in Layout Directory:

Must be under qmk_firmware/layouts/, and in a keymap folder.

qmk compile -kb <keyboard_name>

Example:

$ cd ~/qmk_firmware/layouts/community/60_ansi/mechmerlin-ansi
$ qmk compile -kb dz60
Ψ Compiling keymap with make dz60:mechmerlin-ansi
...

Parallel Compilation:

It is possible to speed up compilation by adding the -j/--parallel flag.

qmk compile -j <num_jobs> -kb <keyboard_name>

The num_jobs argument determines the maximum number of jobs that can be used. Setting it to zero will enable parallel compilation without limiting the maximum number of jobs.

qmk compile -j 0 -kb <keyboard_name>

qmk flash

This command is similar to qmk compile, but can also target a bootloader. The bootloader is optional, and is set to :flash by default. To specify a different bootloader, use -bl <bootloader>. Visit the Flashing Firmware guide for more details of the available bootloaders.

This command is directory aware. It will automatically fill in KEYBOARD and/or KEYMAP if you are in a keyboard or keymap directory.

This command can also flash binary firmware files (hex or bin) such as the ones produced by Configurator.

Usage for Configurator Exports:

qmk flash [-bl <bootloader>] [-c] [-e <var>=<value>] [-j <num_jobs>] <configuratorExport.json>

Usage for Keymaps:

qmk flash -kb <keyboard_name> -km <keymap_name> [-bl <bootloader>] [-c] [-e <var>=<value>] [-j <num_jobs>]

Usage for pre-compiled firmwares:

Note: The microcontroller needs to be specified (-m argument) for keyboards with the following bootloaders:

• HalfKay
• QMK HID
• USBaspLoader

ISP flashing is also supported with the following flashers and require the microcontroller to be specified:

• USBasp
• USBtinyISP

qmk flash [-m <microcontroller>] <compiledFirmware.[bin|hex]>

Listing the Bootloaders

qmk flash -b

qmk config

This command lets you configure the behavior of QMK. For the full qmk config documentation see CLI Configuration.

Usage:

qmk config [-ro] [config_token1] [config_token2] [...] [config_tokenN]

qmk cd

This command opens a new shell in your qmk_firmware directory.

Note that if you are already somewhere within QMK_HOME (for example, the keyboards/ folder), nothing will happen.

To exit out into the parent shell, simply type exit.

Usage:

qmk cd

qmk find

This command allows for searching through keyboard/keymap targets, filtering by specific criteria. info.json and rules.mk files contribute to the search data, as well as keymap configurations, and the results can be filtered using "dotty" syntax matching the overall info.json file format.

For example, one could search for all keyboards using STM32F411:

qmk find -f 'processor=STM32F411'

...and one can further constrain the list to keyboards using STM32F411 as well as rgb_matrix support:

qmk find -f 'processor=STM32F411' -f 'features.rgb_matrix=true'

The following filter expressions are also supported:

• exists(key): Match targets where key is present.
• absent(key): Match targets where key is not present.
• contains(key, value): Match targets where key contains value. Can be used for strings, arrays and object keys.
• length(key, value): Match targets where the length of key is value. Can be used for strings, arrays and objects.

You can also list arbitrary values for each matched target with --print:

qmk find -f 'processor=STM32F411' -p 'keyboard_name' -p 'features.rgb_matrix'

Usage:

qmk find [-h] [-km KEYMAP] [-p PRINT] [-f FILTER]

options:
  -km KEYMAP, --keymap KEYMAP
                        The keymap name to build. Default is 'default'.
  -p PRINT, --print PRINT
                        For each matched target, print the value of the supplied info.json key. May be passed multiple times.
  -f FILTER, --filter FILTER
                        Filter the list of keyboards based on their info.json data. Accepts the formats key=value, function(key), or function(key,value), eg. 'features.rgblight=true'. Valid functions are 'absent', 'contains', 'exists' and 'length'. May be passed multiple times; all filters need to match. Value may include wildcards such as '*' and '?'.

qmk console

This command lets you connect to keyboard consoles to get debugging messages. It only works if your keyboard firmware has been compiled with CONSOLE_ENABLE=yes.

Usage:

qmk console [-d <pid>:<vid>[:<index>]] [-l] [-n] [-t] [-w <seconds>]

Examples:

Connect to all available keyboards and show their console messages:

Show timestamps and VID:PID instead of names:

qmk console -n -t

Disable bootloader messages:

qmk console --no-bootloaders

qmk doctor

Usage:

qmk format-json [-f FORMAT] <json_file>

qmk info

Displays information about keyboards and keymaps in QMK. You can use this to get information about a keyboard, show the layouts, display the underlying key matrix, or to pretty-print JSON keymaps.

Usage:
