This repository contains the unofficial GNU Bash (bash) 3.1.23-2 release for MinGW/MSYS. This package is intended to be used on MSYS only, and was created to replace the bugged 3.1.23-1 which is the only one officially provided in the MinGW/MSYS repository.
Indeed, while trying to create a heredoc, you may have the following issue on some Windows 10/11 editions (tested on Windows 10 Home 22H2):
bash: cannot create temp file for here document: Permission denied
This issue was identified in the past by the Cygwin team but for some reason, the fix was removed by the MinGW team. This patch restore this.
Note: Temporary files created by the heredoc creation process are not
removed from the %TEMP% directory, due to a Permission denied (Errno 13)
issue - this could be explained as in *nix system, it's allowed to unlink a file
even if you have opened it, which isn't the case on Windows.
- Download the
bash-3.1.23-2-msys-1.0.19-bin.tar.xz. - Extract the package file in your
%MINGW_ROOT%\msys\1.0\directory, where%MINGW_ROOT%is the MinGW installation directory (typicallyC:\MinGW).
If you want to recompile this source, you will need to have a working
MSYS Toolchain.
Then, follow the instructions in the src/msys-bash.RELEASE_NOTES file.
