Configuring mintty

Mintty supports a number of common places to look for and save its configuration and resources.

For its configuration file, it reads /etc/minttyrc, $APPDATA/mintty/config, ~/.config/mintty/config, ~/.minttyrc, in this order.

For resource files to configure a colour scheme, wave file for the bell character, or localization files, it looks for subfolders themes, sounds, or lang, respectively, in one of the directories ~/.mintty, ~/.config/mintty, $APPDATA/mintty, /usr/share/mintty, whichever is found first.

The ~/.config/mintty folder is the XDG default base directory. The $APPDATA/mintty folder is especially useful to share common configuration for various installations of mintty (e.g. cygwin 32/64 Bit, MSYS, Git Bash).

Using desktop shortcuts to start mintty

The Cygwin setup.exe package for mintty installs a shortcut in the Windows start menu under All Programs/Cygwin. It starts mintty with a ‘-’ (i.e. a single dash) as its only argument, which tells it to invoke the user’s default shell as a login shell.

Shortcuts are also a convenient way to start mintty with additional options and different commands. For example, shortcuts for access to remote machines can be created by invoking ssh. The command simply needs to be appended to the target field of the shortcut’s properties:

Target: C:\Cygwin\bin\mintty.exe /bin/ssh server

The cygutils package provides the mkshortcut utility for creating shortcuts from the command line. See its manual page for details.

A Windows shortcut can be associated with a Shortcut key so an instance of mintty can be started using a hotkey. By default, an already running instance would be focussed again with the associated hotkey. To have a new instance started with every usage of the hotkey, use the command-line option -D for mintty in the shortcut target.

Note: About interaction problems of icon, shortcut, and the Windows taskbar: In a Windows desktop shortcut, to achieve consistent icon behaviour, the same icon should be specified in the shortcut properties (Change Icon...) and the mintty command line (Target:), or (beginning 2.2.3) no icon should be specified on the command line as mintty will then take the icon from the invoking shortcut.

Note: It is suggested to not use the option AppID in a Windows desktop shortcut, or follow the advice about avoiding trouble with taskbar grouping in the manual page.

Supporting Linux/Posix subsystems

If you have any Linux distribution for the Windows Subsystem for Linux (WSL) installed, mintty can be called from cygwin to run a WSL terminal session:

  • mintty --WSL=Ubuntu
  • mintty --WSL (for the Default distribution as set with wslconfig /s)

Note, the wslbridge tool needs to be installed in /bin for this purpose (see below for details).

A WSL terminal session can be configured for the mintty session launcher in the config file, like:

  • SessionCommands=Ubuntu:--WSL=Ubuntu

WSLtty, the standalone WSL mintty terminal

For a standalone mintty deployment as a WSL terminal, also providing desktop and start menu shortcuts, command line launch scripts, and optional Windows Explorer integration, install wsltty, using either the wsltty installer, a Chocolatey package, or a Windows Appx package.

Manual setup of WSL terminal

To help reproduce the installation manually, for users of cygwin or msys2:

  • From, download the wslbridge archive corresponding to your system (cygwin/msys2 32/64 bit)
  • Install wslbridge.exe and wslbridge-backend into your cygwin or msys2 /bin directory
  • Make a desktop shortcut (Desktop right-click – New ▸ Shortcut) with
    • Target: X:\cygwin64\bin\mintty.exe --WSL=Linux_Distribution -
    • Icon location (Change Icon…) for Legacy “Ubuntu on Windows”: %LOCALAPPDATA%\lxss\bash.ico

Replace X:\cygwin64 with your cygwin or msys2 root directory path and Linux_Distribution with your preferred distribution. The suitable icon location for each respective distribution is not easily found; the standalone package would set that up for you in the shortcuts. For other invocation (cygwin or Windows command line), mintty finds the suitable WSL icon itself.

At the end of the mintty --WSL invocation line, you may add an explicit WSL shell invocation like /bin/bash -l to select your favourite shell or ask for a login shell (-l), or set a start directory (-C, before any shell command) if desired.

If no start directory is otherwise selected, the “Start in:” directory of the shortcut may be set to %USERPROFILE%.


On Windows 7, mintty may also be used as a terminal for the Subsystem for UNIX-based applications (SUA), also known as Interix. For the mintty session launcher, this can be configured for the available shells as follows (concatened with ‘;’ separator for multiple targets):

  • SessionCommands=Interix Korn Shell:/bin/winpty C:\Windows\posix.exe /u /c /bin/ksh -l
  • SessionCommands=Interix SVR-5 Korn Shell:/bin/winpty posix /u /p /svr-5/bin/ksh /c -ksh
  • SessionCommands=Interix C Shell:/bin/winpty posix /u /c /bin/csh -l

For a desktop or start menu shortcut, the respective target command would look like X:\cygwin\bin\mintty.exe winpty … (and may use the icon location %SystemRoot%\Installer{DB88A98A-792B-4441-8E60-05A6D3E2B2C0}\sh.exe).

Starting mintty from a batch file

In order to start mintty from a batch file it needs to be invoked through the start command. This avoids the batch file’s console window staying open while mintty is running. For example:

start mintty -

The console window for the batch file will still show up briefly, however. This can be avoided by invoking mintty from a shortcut instead, as described above.

Starting in a particular directory

The working directory for a mintty session can be set in the Start In field of a shortcut, or by changing directory in an invoking script, or with option --dir. Note, however, that Cygwin’s /etc/profile script for login shells automatically changes to the user’s home directory. The profile script can be told not to do this by setting a variable called CHERE_INVOKING, like this:

mintty /bin/env CHERE_INVOKING=1 /bin/bash -l

Note: If mintty is run from a shortcut with empty Start In field and the effective start directory is within the Windows system folder, mintty changes it in order to avoid failure when creating a log file.

Creating a folder context menu entry for mintty

Cygwin’s chere package can be used to create folder context menu entries in Explorer, which allow a shell to be opened with the working directory set to the selected folder.

The following command will create an entry called Bash Prompt Here for the current user that will invoke bash running in mintty. See the chere manual (man chere) for all the options.

chere -1 -i -c -t mintty

Note, however, that context menu entries created by chere fail on non-ASCII directory names. Mintty option --dir comes to help, like in either of these registry entries for registry keys like /HKCU/Software/Classes/Directory/Shell/mintty-here/command/:

C:\cygwin64\bin\mintty.exe --dir "%1" /bin/bash
C:\cygwin64\bin\mintty.exe --dir "%1" /bin/env CHERE_INVOKING=1 /bin/bash -l

Setting environment variables

Unfortunately Windows shortcuts do not allow the setting of environment variables. Variables can be set globally though via a button on the Advanced tab of the system properties. Those can be reached by right-clicking on the (My) Computer entry in the start menu or on the desktop, selecting Properties, then Advanced System Settings.

Alternatively, global variables can be set using the setx command line utility. This comes pre-installed with some versions of Windows but is also available as part of the freely downloadable Windows 2003 Resource Kit Tools.

The env utility can be used to set variables specifically for the program to be run in mintty, e.g.:

mintty /bin/env DISPLAY=:0 /bin/ssh -X server

Input/Output interaction with alien programs

When interacting with programs that use a native Windows API for command-line user interaction (“console mode”), a number of undesirable effects are observed; this is the pty incompatibility problem and the character encoding incompatibility problem. This basically affects all programs not compiled in a cygwin or msys environment (and note that MinGW is not msys in this context).

As a workaround, you can use winpty as a wrapper to invoke the Windows program.

Note: There is no point in reporting this for the 15th time as a mintty issue, because it is not a mintty issue (or well, an issue maybe, but not caused by, or fixable by, mintty); it is a generic problem of cygwin/msys and occurs likewise in all other pty-based terminals (e.g. xterm).

Terminal line settings

Terminal line settings can be viewed or changed with the stty utility, which is installed as part of Cygwin’s core utilities package. Among other things, it can set the control characters used for generating signals or editing an input line.

See the stty manual for all the details, but here are a few examples. The commands can be included in shell startup files to make them permanent.

To change the key for deleting a whole word from Ctrl+W to Ctrl+Backspace:

stty werase '^_'

To use Ctrl+Enter instead of Ctrl+D for end of file:

stty eof '^^'

To use Pause and Break instead of Ctrl+Z and Ctrl+C for suspending or interrupting a process:

stty susp '^]' swtch '^]' intr '^\'

With these settings, the Esc key can also be used to interrupt processes by setting its keycode to ^\:

echo -ne '\e[?7728h'

(The standard escape character ^[ cannot be used for that purpose because it appears as the first character in many keycodes.)

Unix terminal line drivers have a flow control feature that allow terminal output to be stopped with Ctrl+S and restarted with Ctrl+Q. However, due to the scrollback feature in modern terminal emulators, there is little need for this. Hence, to make those key combinations available for other uses, disable flow control with this command:

stty -ixon

Readline configuration

Keyboard input for the bash shell and other programs that use the readline library can be configured with the so-called inputrc file. Unless overridden by setting the INPUTRC variable, this is located at ~/.inputrc. It consists of bindings of keycodes to readline commands, whereby comments start with a hash character. See its manual for details.

Anyone used to Windows key combinations for editing text might find the following bindings useful:

# Ctrl+Left/Right to move by whole words
"\e[1;5C": forward-word
"\e[1;5D": backward-word

# Ctrl+Backspace/Delete to delete whole words
"\e[3;5~": kill-word
"\C-_": backward-kill-word

# Ctrl+Shift+Backspace/Delete to delete to start/end of the line
"\e[3;6~": kill-line
"\xC2\x9F": backward-kill-line  # for UTF-8
#"\x9F": backward-kill-line     # for ISO-8859-x
#"\e\C-_": backward-kill-line   # for any other charset

# Alt-Backspace for undo
"\e\d": undo

(The Ctrl+Shift+Backspace keycode depends on the selected character set, so the appropriate binding needs to be chosen.)

Finally, a couple of bindings for convenient searching of the command history. Just enter the first few characters of a previous command and press Ctrl+Up to look it up.

# Ctrl+Up/Down for searching command history
"\e[1;5A": history-search-backward
"\e[1;5B": history-search-forward

Keyboard not working as expected in certain applications (e.g. vim)

If for example the PgUp and PgDn keys do not work in your editor, the reason may be that in the mintty Options, the Terminal Type was set to "vt100" and based on the resulting setting of the environment variable TERM, the application expects other key sequences than mintty sends. (While mintty could be changed to send VT100 application keypad codes in that case, the current behaviour is compatible with xterm.)

Shift+up/down for text selection in emacs

The escape sequences for Shift+up/down are mapped to scroll-backward/forward virtual keys by the xterm terminfo entry. Follow the advice in How to fix emacs shift-up key... to create a fixed terminfo entry that removes this mapping, or use a suitable alternative setting for the environment variable TERM, for example TERM=xterm-color.

Mode-dependent cursor in vim

Mintty supports control sequences for changing cursor style. These can be used to configure vim such that the cursor changes depending on mode. For example, with the following lines in ~/.vimrc, vim will show a block cursor in normal mode and a line cursor in insert mode:

let &t_ti.="\e[1 q"
let &t_SI.="\e[5 q"
let &t_EI.="\e[1 q"
let &t_te.="\e[0 q"

Avoiding escape timeout issues in vim

It’s a historical flaw of Unix terminals that the keycode of the escape key, i.e. the escape character, also appears at the start of many other keycodes. This means that on seeing an escape character, an application cannot be sure whether to treat it as an escape key press or whether to expect more characters to complete a longer keycode.

Therefore they tend to employ a timeout to decide. The delay on the escape key can be annoying though, particularly with the mode-dependent cursor above enabled. The timeout approach can also fail on slow connections or a heavily loaded machine.

Mintty’s “application escape key mode” can be used to avoid this by switching the escape key to an unambiguous keycode. Add the following to ~/.vimrc to employ it in vim:

let &t_ti.="\e[?7727h"
let &t_te.="\e[?7727l"
noremap <Esc>O[ <Esc>
noremap! <Esc>O[ <Esc>

Note that the last line causes vi-compatible behaviour to be used when pressing Esc on the command line: the command is executed rather than cancelled as is the default for vim. If the latter is preferred, replace the last line with a mapping to ^C:

noremap! <Esc>O[ <C-c>

Using Ctrl+Tab to switch window pane in terminal multiplexers

The Ctrl+Tab and Ctrl+Shift+Tab key combinations can be used to switch windows/panes/tabs in a terminal multiplexer session. In order to do so, their use as shortcuts for switching mintty windows needs to be disabled on the Keys page of the options, and their keycodes need to be mapped as shown below.

Switch window in GNU Screen

For GNU Screen, in ~/.screenrc:

bindkey "^[[1;5I" next
bindkey "^[[1;6I" prev

Switch pane in tmux

For tmux, in ~/.tmux.conf:

set -s user-keys[0] "\e[1;5I"
set -s user-keys[1] "\e[1;6I"
bind-key -n User0 next-window
bind-key -n User1 previous-window

Compose key

Mintty uses the Windows keyboard layout system with its “dead key” mechanism for entering accented characters, enhanced by self-composed characters for dead-key combinations that Windows does not support (e.g. ẃ).

Mintty also provides a Compose key, configurable to Control, Shift or Alt, using X11 compose data. For example, if the compose key is configured to be Control, pressing and release the Control key, followed by letters a and e, will enter æ; Control---, will enter ¬, Control-C-o will enter ©, Control-<-< will enter «, Control-c-, will enter ç, Control-s-s will enter ß, Control-!-! will enter ¡, Control-!-? will enter , etc.

For a separate compose key solution, the most seamless and stable Compose Key for Windows is WinCompose.

Changing colours

The default foreground, background and cursor colours can be changed in the options dialog, or by specifying the ForegroundColour, BackgroundColour and CursorColour settings in the configuration file or on the command line.

However, they can also be changed from within the terminal using the xterm control sequences for this purpose, for example:

echo -ne '\e]10;#000000\a'  # Black foreground
echo -ne '\e]11;#C0C0C0\a'  # Light gray background
echo -ne '\e]12;#00FF00\a'  # Green cursor

In mintty, the RGB colour values can also be specified using a comma-separated decimal notation, for example 255,0,0 instead of #FF0000 for red. X11 colour names are supported, too. See the examples below for all options.

The 16 ANSI colours can be set in the configuration file or on the command line using settings such as Blue or BoldMagenta. These are documented in the configuration section of the manual. They can also be changed using xterm control sequences. Here they are with their default values:

echo -ne '\e]4;0;#000000\a'   # black
echo -ne '\e]4;1;#BF0000\a'   # red
echo -ne '\e]4;2;#00BF00\a'   # green
echo -ne '\e]4;3;#BFBF00\a'   # yellow
echo -ne '\e]4;4;#0000BF\a'   # blue
echo -ne '\e]4;5;#BF00BF\a'   # magenta
echo -ne '\e]4;6;#00BFBF\a'   # cyan
echo -ne '\e]4;7;#BFBFBF\a'   # white (light grey really)
echo -ne '\e]4;8;#404040\a'   # bold black (i.e. dark grey)
echo -ne '\e]4;9;#FF4040\a'   # bold red
echo -ne '\e]4;10;#40FF40\a'  # bold green
echo -ne '\e]4;11;#FFFF40\a'  # bold yellow
echo -ne '\e]4;12;#6060FF\a'  # bold blue
echo -ne '\e]4;13;#FF40FF\a'  # bold magenta
echo -ne '\e]4;14;#40FFFF\a'  # bold cyan
echo -ne '\e]4;15;#FFFFFF\a'  # bold white

Different notations are accepted for colour specifications:

  • #RRGGBB (256 hex values, see examples above)
  • rrr,ggg,bbb (256 decimal values)
  • rgb:RR/GG/BB (256 hex values)
  • rgb:RRRR/GGGG/BBBB (65536 hex values)
  • cmy:C.C/M.M/Y.Y (float values between 0 and 1)
  • cmyk:C.C/M.M/Y.Y/K.K (float values between 0 and 1)
  • color-name (using X11 color names, e.g. echo -ne '\e]10;bisque2\a')

Using colour schemes (“Themes”)

Colour schemes (that redefine ANSI colours and possibly foreground/background colours) can be loaded with the option -C (capital C) or --loadconfig which loads a configuration file read-only, i.e. configuration changes are not saved to this file, or with the new setting ThemeFile.

In the Options menu, section Looks, the Theme popup offers theme files as stored in a resource directory for selection. This dialog field (or the “Color Scheme Designer” button for drag-and-drop) can be used in different ways:

  • Popup the selection to choose a theme configured in your resource directory
  • Insert a file name (e.g. by pasting or drag-and-drop from Windows Explorer)
  • Drag-and-drop a theme file from the Internet (may be embedded in HTML page)
  • Drag-and-drop a colour scheme directly from the Color Scheme Designer (see below)

After drag-and-drop of a colour scheme, you may Apply it for testing; to keep the scheme in your popup selection, assign a name to it by typing it into the Theme field, then click the “Store” button. After downloading a theme file, the name will be filled with its basename as a suggestion. As long as a colour scheme is loaded but not yet stored, and a name is available in the Theme field, the “Store” button will be enabled.

There is an excellent colour scheme designer available: 4bit Terminal Color Scheme Designer which lets you download a tuned colour scheme (top-right button “Get Scheme”). Click on the button “Color Scheme Designer” below the Theme field to open the designer page and start your design. You can either download the scheme file (“Get Scheme” – “mintty”) or drag-and-drop the download link directly to the mintty Options menu, to either the Theme field or the Color Scheme Designer button. You can then click Apply to test the design and if you like it, you can enter a theme name in the Theme field and then click the “Store” button to store the colour scheme.

A number of colour schemes have been published for mintty, e.g.

Mintty also provides the command-line script mintheme which can display the themes available in the mintty configuration directories or activate one of them in the current mintty window.

Providing and selecting fonts

To provide additional fonts for use with mintty, monospace fonts can be installed in Windows. Note that font installation in X11 does not make a font available for mintty as mintty is not an X windows application. Some monospace fonts are not explicitly marked as such in the font file. In that case the font will not be listed in the mintty Options – Text – Font selection menu. It can still be used by explicit selection, e.g.:

mintty -o Font="Linux Libertine Mono"

Also, Unicode font names are now supported, e.g.

mintty -o Font=Sütterlin
mintty -o Font=옹달샘

The font selection menu lists monospace fonts unless marked to Hide in the Fonts folder of the system Control Panel. To include them in the fonts offered in the menu (e.g. to select any of DotumChe, GulimChe, GungsuhChe, MingLiU, MS Gothic, MS Mincho, NSimSun, Simplified Arabic Fixed), do either of:

  • Uncheck “Hide fonts based on language settings” in Fonts ▸ Font settings
  • Hide/Show fonts individually from their context menu
  • Set the mintty hidden setting ShowHiddenFonts=true

The latter setting also includes fonts with an OEM or SYMBOL character set.

Some fonts with a name problem (e.g. Meslo LG S for Powerline) can be selected using the new Apply button in the font selection menu.

Fonts not listed in the menu can be configured with the Font setting.

The old font selection and menu format can be chosen with setting FontMenu=1.

If you are missing certain characters, e.g. as used for the popular “Powerline” plugin, the reason may be that specifically designed characters are being addressed that are provided in the Unicode Private Use range of dedicated fonts; a collection of such fonts can be found at Nerd Fonts.

Alternative fonts

Mintty supports up to 10 alternative fonts that can be selected as character attributes (see Text attributes below). They are configured in the config file (see manual page), except for font 10 which has a default preference; mintty will try to find a Fraktur or Blackletter font for it on your system.

Character width

By default, mintty adjusts character width to the width assumption of the locale mechanism (function wcwidth). If it is desired to use more up-to-date Unicode width properties, this can be chosen with option Charwidth=unicode. Note that actual width properties as rendered on the screen and width assumptions of the wcwidth function will be inconsistent then for the impacted characters, which may confuse screen applications (such as editors) that rely on wcwidth information.

Ambiguous width setting

A number of Unicode characters have an “ambiguous width” property due to legacy issues with dedicated CJK fonts, meaning they can be narrow (single-cell width) or wide (double-cell width) in a terminal.

To select ambiguous-width characters to appear wide (as some applications may expect), mintty should be run in a CJK locale (character encoding does not need to be CJK), e.g.:

LC_CTYPE=zh_SG.utf8 mintty &

If the locale is selected via the Locale setting, however, it is necessary to choose an ambiguous-wide font in addition (CJK font), or mintty will enforce the ambiguous-narrow mode of rendering by appending the “@cjknarrow” locale modifier:

mintty -o Locale=zh_CN -o Font=FangSong &

If it is not desired to set a specific base locale in order to enable ambiguous-wide mode, option Charwidth=ambig-wide can be used. It implies Charwidth=unicode behaviour, with the same caveats as above. Mintty indicates this mode by appending the @cjkwide modifier to the LC_CTYPE locale variable (not yet supported by cygwin).

Selective double character width

While mintty fully supports double-width characters (esp. CJK) as well as ambiguous-width characters, there are also characters of fuzzy width property, because their rendered glyph is wider than one terminal character cell in most fonts, but yet they are defined as single-width by Unicode. Such characters often appear to be clipped on the screen. Mintty has an experimental feature to display semi-wide Indic and some other characters at double-cell width (see Control Sequences – Wide characters), but not all such characters are handled, and there is no perfect solution that would also comply with the locale mechanism unless the terminal would support proportional fonts.

Font rendering and geometry

Mintty can make use of advanced Windows font fallback as provided via the Uniscribe API, achieving improved character/glyph substitution for characters not provided in the selected font. Option -o FontRender=uniscribe is now the default, -o FontRender=textout disables it. Note that Uniscribe is not applied to right-to-left text as it would interfere with mintty’s own bidi transformation.

Window geometry, rows and columns

The actual window size is influenced by several parameters:

  • Font size / character height is the main parameter to determine the row height.
  • Row height is additionally affected by the “leading” information from the font.
  • Row height and column width can furthermore be tuned with setting RowSpacing and ColSpacing.
  • A gap between text and window border can be specified with setting Padding (default 1).

Note: The term “leading” (pronounced like “ledding”) comes from the times of metal typesetting when strips of lead (the metal) were used to adjust line spacing.

Text attributes and rendering

Mintty supports a maximum of usual and unusual text attributes. For underline styles and colour values, colon-separated ISO/IEC 8613-6 sub-parameters are supported.

start ^[[...m end ^[[...m attribute
1 22 bold
2 22 dim
3 23 italic
4 or 4:1 24 or 4:0 solid underline
4:2 24 or 4:0 double underline

any 0

Note: The control sequences for Fraktur (“Gothic”) font are described in ECMA-48, see also wiki:ANSI code. To use this feature, it is suggested to install F25 Blackletter Typewriter.

Note: The control sequence for alternative font 1 overrides the identical control sequence to select the VGA character set. Configuring alternative font 1 is therefore discouraged. See the mintty manual page about how to configure alternative fonts.

Note: RGB colour values are scaled to a maximum of 255 (=100%). CMY(K) colour values are scaled to a maximum of the given parameter F (=100%).

Note: The emoji style attribute sets the display preference for a number of characters that have emojis but would be displayed with text style by default (e.g. decimal digits).

As a fancy add-on feature for text attributes, mintty supports distinct colour attributes for combining characters, so a combined character can be displayed in multiple colours. Attributes considered for this purpose are default and ANSI foreground colours, palette and true-colour foreground colours, dim mode and manual bold mode (BoldAsFont=false); background colours and inverse mode are ignored.


Mintty supports display of emojis as defined by Unicode using emoji presentation, emoji style variation and emoji sequences.

The option Emojis can choose among sets of emoji graphics if deployed in a mintty configuration directory. With this option, mintty emoji support is enabled and the emoji graphics style is chosen. Mintty will match output for valid emoji sequences, emoji style selectors and emoji presentation forms.

For characters with default text style but optional emoji graphics, emoji style can be selected with the “framed” or “encircled” text attribute.

Note that up to cygwin 2.10.0, it may be useful to set Charwidth=unicode in addition.

Emojis are displayed in the rectangular character cell group determined by the cumulated width of the emoji sequence characters. The option EmojiPlacement can adjust the location of emoji graphis within that area.

Installing emoji resources

Mintty does not bundle actual emoji graphics with its package. You will have to download and deploy them yourself.

Emoji data can be found at the following sources:

  • EmojiOne
    • Free Download for your own use, PNG Files, download e.g. 128x128px zip
    • Deploy the preferred subdirectory (e.g. 128) as emojione
  • Noto Emoji font, subdirectory png/128
    • “Clone or download” the repository or download a release archive
    • Deploy subdirectory noto-emoji/png/128 as noto
  • Full Emoji List (~50MB)
    • Download the Full Emoji List (with all emoji data embedded)
    • Use the extraction script getemojis to extract emoji data (call it without parameters for instructions)
    • Deploy the desired subdirectories (e.g. apple)
    • Includes apple, emojione, facebook, google, twitter, samsung, windows emojis (and some limited low-resolution sets that we shall ignore)
  • Emoji data and images
    • “Clone or download” the repository or download a release archive
    • Deploy subdirectories img-* as appropriate (e.g. img-apple-64 as apple)
    • Includes apple, emojione-2D, facebook, facebook messenger (discontinued), google, twitter emojis

To “Clone” with limited download volume, use the command git clone --depth 1. To download only the desired subdirectory from, use subversion, for example:

  • svn export noto
  • svn export apple

“Deploy” above means move, link, copy or hard-link the respective subdirectory into mintty configuration resource subdirectory emojis, e.g.

  • mv noto-emoji/png/128 ~/.config/mintty/emojis/noto
  • ln -s "$PWD"/noto-emoji/png/128 ~/.config/mintty/emojis/noto
  • cp -rl noto-emoji/png/128 ~/.config/mintty/emojis/noto

Use your preferred configuration directory, e.g.

  • cp -rl noto-emoji/png/128 "$APPDATA"/mintty/emojis/noto
  • cp -rl noto-emoji/png/128 /usr/share/mintty/emojis/noto

Searching in the text and scrollback buffer

With the Search menu command or Alt+F3, a search bar is opened. Matching is case-insensitive and ignores combining characters. Matches are highlighted in the scrollback buffer. The appearance of the search bar and the matching highlight colours can be customized.

Another search feature (Shift+cursor-left/right) skips to the previous/next prompt line if these are marked with scroll marker escape sequences, see the CtrlSeqs wiki page.

Passing arguments from an environment with different character set

To pass non-ASCII parameters to a command run from mintty using a specific character encoding, proper conversion must be crafted. See issue #463 for a discussion. For example, for a desktop shortcut to start a GBK-encoded mintty starting in a specific directory with a non-ASCII name, use this command line as a shortcut target:

C:\cygwin\bin\mintty.exe -o Locale=C -o Charset=GBK /bin/bash -l -c "cd `echo D:/桌面 | iconv -f UTF-8`; exec bash"

So the initial shell, interpreting its cd parameters already in GBK encoding, will see it properly converted.

Spawning a new terminal window in the same directory

With Alt+F2, normally another mintty window would be opened in the home directory (or where the current window was started), while it may be desirable to open it in the same directory as the current working directory. This can be achieved with some interaction between the shell and the terminal, as applied e.g. by the Mac Terminal. The shell can inform the terminal about a changed directory with the OSC 7 control sequence (see the CtrlSeqs wiki page), to be output with the prompt (example for bash):

PROMPT_COMMAND='echo -ne "\e]7;$PWD\a" ; '"$PROMPT_COMMAND"

The sequence could also be output by shell aliases or functions changing the directory. It cannot be embedded in the prompt itself with \w as that is using some shortcuts, but $PWD could be used if shopt promptvars is not unset.

Note that after remote login, the directory path may be meaningless unless the remote and local paths match. Note also that from a login terminal (e.g. using parameter - to start a login shell), Alt+F2 starts again a login terminal, whose login shell is likely to reset the working directory to the home directory.

Virtual Tabs

The Virtual Tabs feature provides a list of all running mintty sessions as well as configurable launch parameters for new sessions. By default, the list is shown in the extended context menu (Ctrl+right-click), the mouse button 5 menu, and the menus opened with the Ctrl+Menu key and the Ctrl+Shift+I shortcut (if enabled). (Menu contents for the various context menu invocations is configurable.) For configuration, see settings SessionCommands, Menu*, and SessionGeomSync. Distinct sets of sessions can be set up with the setting -o Class=....

Multi-monitor support

Mintty supports multiple monitors with two features:

A mintty window can be placed on a specific monitor with the command-line option -p @N where N is the number of the monitor.

A new mintty window cloned with Alt+F2 can be placed on a selected monitor while F2 is being held; press cursor and other keys on the numeric keypad to navigate the monitor grid to the desired target monitor, then release F2.

Note also the generic Windows hotkeys to move the current window to the left or right neighbour monitor: Win+Shift+cursor-left/right.

Embedding graphics in terminal output

The new support of the SIXEL feature facilitates a range of applications that integrate graphic images in the terminal, animated graphics, and even video and interactive gaming applications.

An example of the benefit of this feature is the output of gnuplot with the command

export GNUTERM=sixel
gnuplot -e "splot [x=-3:3] [y=-3:3] sin(x) * cos(y)"

Note that gnuplot uses black text on default background for captions and coordinates so better not run it in a terminal with dark background.


Mintty facilitates localization of its user interface, the Options dialog, menus, message boxes, and terminal in-line error messages. The localization language can be selected with the option Language, see manual page for details.

Example: Language=*, environment variables LANGUAGE=de_CH:français:de:fr_FR and LC_MESSAGES=en_GB.UTF-8, LC_ALL not set: mintty tries to find localization files (in this order) for de_CH, français, de, fr_FR, en_GB, then (as generic fallback) fr and en, each in all resource configuration folders (subfolder lang).

Note that Windows may already have localized the default entries of the system menu, which makes the system menu language inconsistent because mintty adds a few items here. Choose Language=en to “reverse-localize” this, as well as the font and colour chooser dialogs.

Choose Language=en_US to change Colour to Color in the menus.

Adding translations to localization

Localization files for various language or language/region codes are looked up in the resource configuration folders, subfolder lang. Mintty uses a simplified gettext file format but not the gettext library; all messages must be encoded in UTF-8, the Content-Type charset is ignored.

To add a new language, copy messages.pot to the desired .po file (including a region suffix if appropriate, like fr_CH) and add the msgstr entries which are empty in the template. The tool poedit may be used but remember to use UTF-8 encoding.

Note: There is one special pseudo-string in the localization template which facilitates scaling of the Options dialog width. It is labelled “__ Options: dialog width scale factor (80...200)” and its template value is “100”. If you provide a pseudo-translated value between 80 and 200 for it, the Options dialog width will be scaled by that percentage. (The navigation panel remains unscaled.)

Note that & marks in menu item labels define keyboard shortcuts to be handled by Windows. The script keycheck with your .po file as parameter checks for ambiguous shortcut entries; these are not errors but you may consider to reduce ambiguities. Note that a future (or currently patched) version of the uniq tool is needed to cover non-ASCII keyboard shortcuts.

Character information display

Diagnostic display of current character information can be toggled from the extended context menu (Ctrl+right-click).

  • Unicode character codes at the current cursor position will then be displayed in the window title bar. (Note that mintty may precompose a combining character sequence into a combined character which is then displayed.)
  • Unicode character names will be included in the display if the unicode-ucd package is installed in /usr/share (or the file charnames.txt generated by the mintty script src/mknames is installed in the mintty resource subfolder info).
  • Emoji sequence “short names” will be indicated if Emojis display is enabled. Note that the “normal” window title setting sequence and the character information output simply overwrite each other.

User-defined behaviour

Mintty supports two extension features:

  • Application-specific drag-and-drop transformations (option DropCommands)
  • User-defined commands and filter functions (option UserCommands)

See the manual page for details.

Terminating the foreground program

As an example for a user-defined command, that is not used for filtering text in this case, assume the user wants a menu option to terminate the terminal foreground process (in case it is stalled). This can be done by including a user command:

UserCommands=Kill foreground process:kill -9 $MINTTY_PID

Running mintty stand-alone

To install mintty outside a cygwin environment, follow a few rules:

  • Find out which libraries (dlls from the cygwin /bin directory) mintty needs in addition to cygwin1.dll and install them all, or:
  • Compile mintty statically.
  • Call the directory in which to install mintty and libraries ‘bin’.
