wsltty/README.md

Mintty as a terminal for Bash on Ubuntu on Windows / WSL.

Overview

Run the installer to install

• wsltty package components (see below) in the user’s application folder (where WSL is also installed)
• an empty wsltty “home directory” to enable storage of a mintty config file
• Start Menu and Desktop shortcuts to start a WSL bash (with some variations, see below)
• optional context menu entries for Windows Explorer to start a WSL bash in the respective folder
• install/uninstall context menu items from Start Menu subfolder
• wsl*.bat scripts to invoke wsltty manually (with some variations and invocation options, see below)
• an uninstall script that can be invoked manually to remove shortcuts and context menu entries

If Windows complains with a “Windows protected your PC” popup, you may need to click “Run anyway” to proceed with the installation. You may need to open the Properties of the installer first, tab “General” section “Security” (if available) and select “Unblock”, to enable the “Run anyway” button.

Configuration

Command line scripts wsl*.bat

WSLtty installs the following scripts in its application folder %LOCALAPPDATA%\wsltty:

• wsl.bat to start a WSL bash in the current folder/directory
• wsl~.bat to start a WSL bash in the WSL user home
• wsl-l.bat to start a WSL login bash

To enable invocation of these scripts from WIN+R or from cmd.exe, copy them from %LOCALAPPDATA%\wsltty into %SYSTEMROOT%\System32, renaming them as desired. (The package does not do this to avoid trouble with missing admin privileges.)

Start Menu and Desktop shortcuts

The Start Menu subfolder WSLtty offers three shortcuts:

• WSL Bash % in Mintty to start a WSL bash in the Windows %USERPROFILE% home
• WSL Bash ~ in Mintty to start a WSL bash in the WSL user home
• WSL Bash -l in Mintty to start a WSL login bash

To ensure a login bash to start in your Linux home directory, add a cd command to your $HOME/.profile on Linux side.

Mintty settings

Mintty can maintain its configuration file in various locations, with the following precedence:

• file given with mintty option -c
• %HOME%\.minttyrc
• %HOME%\.config\mintty\config
• %APPDATA%\mintty\config
• %LOCALAPPDATA%\wsltty\etc\minttyrc

Note:

• By default, %HOME% would refer to the root directory of the cygwin standalone installation hosting wsltty. So %HOME% would mean %LOCALAPPDATA%\wsltty\home\%USERNAME%. If you define HOME at Windows level, this changes accordingly. Note, however, that the WSL HOME is a completely different setting.
• The %APPDATA%\mintty\config option provides the possibility to maintain common mintty settings for various installations (like wsltty, Cygwin, MinGW/msys, Git for Windows, MinEd for Windows).

Shell selection

To invoke your favourite shell, simply replace /bin/bash with its pathname in the Desktop shortcuts, wsl*.bat invocation scripts, or Explorer context menu commands (configured in config-context-menu.bat).

Components

For mintty, see the Mintty homepage, then Mintty manual page, and the Mintty Wiki, including a Hints and Tips page.

It is based on Cygwin and includes its runtime library (sources).

For interacting with WSL, it uses wslbridge.
