 Normally this is fine, but seldom it breaks programs. To disable it one needs to setup an environment variable: ''MSYS2_ARG_CONV_EXCL'' ([[https://github.com/msys2/msys2/wiki/Porting#filesystem-namespaces|Documentation]]).

 A common example is docker for windows. One probably wants an alias in their ''~/.bashrc''.

 So that Msys2 won't mangle any path.
-==== Admin access ===
+=== TTY-sensible programs ===
+Few programs, like __nodejs__, have problems using Msys2. When you execute them the console seems to hang. It happens because they expect the stdout do be a TTY, in other words stdout must follow the terminal interface protocol.
+The Mysys2 shell does not:
+  $ node -p -e 'Boolean(process.stdout.isTTY)'
+  false
+Fortunately there is a solution: the program **winpty**
+  $ winpty node -p -e "Boolean(process.stdout.isTTY)"
+  true
+Let us see in action:
+  $ node
+Nothing happens, until you press CTRL-C stopping it.
+  $ winpty node
+  Welcome to Node.js v13.11.0.
+  Type ".help" for more information.

+Much better! **winpty** can be installed with pacman.
+==== Admin access ====
 Seldom one needs to execute a command as superuser.
