This matching is not mandatory though, as bash can be run in a Windows console and cmd can be run in mintty. Likewise, when you open a mintty window, you'll probably see the bash shell running inside and waiting for your commands. The "DOS window" in Windows is actually a combination of a Windows console and the Windows shell ( cmd, command line). A shell is the actual program that reads commands from the user and runs them. ShellsĪ distinct category of programs is shells. It provides the back-end to the Windows Console API. The Windows console ( conhost) does the same for Windows programs. There are other terminal emulators in Cygwin, but they're not provided in MSYS2. It provides the necessary POSIX interfaces to MSYS2 programs. Mintty is a terminal emulator built for MSYS2 programs. draw the characters from the programs as corresponding glyphs on the screen). accept keypresses from the user and send corresponding characters to the program) and output (e.g. Terminals are programs that interface with console programs and facilitate their input (e.g. In the POSIX world, REPLs are often programmed using the readline library and TUIs using the ncurses library. MSYS2/POSIX programs use in-band terminal sequences, while Windows programs use out-of-band calls to the Windows Console API. when a program employs a REPL or uses colored output or draws TUIs, the two systems are fundamentally different. it's not interactive), then the program's I/O should be easily portable between Windows, MSYS2 and other platforms. If reading and writing simple text is the only thing a program does (i.e. non-MSYS2 ones) console programs both use character streams to read data from the user and to display data to the user.
MSYS2 (more generally POSIX) and regular Windows (i.e. Note that where we say MSYS2 below, it usually denotes Cygwin as well. If the reader has any corrections or clarifications, please post to the mailing list. The following information is our best understanding and our best attempt at explaining it. Note that this topic is not simple and there are many factors that can cause differences in observed behavior ( TERM, LANG, LC_*.).
GUI (graphical, windowed) programs fall outside of the scope of this text. This is a basic explanation of how console programs work in Cygwin and MSYS2.
