Command Prompt / Console / Windows Subsystem for Linux

Shrouded in the mists of time, the Windows Console was created. For millenia, geeks and developers wrought their command-line tools but after a while, a great lacking was noticed. And so, legions of ever intrepid command-line mavens migrated to other shells and consoles, ’til but a stalwart few remained.

In Windows 10, with a deep rumbling, the ancient, weary, Windows Console heaved a great sigh and began to tremble. New features appeared, but slow was the (aparrent) progress.

But then, in early 2016, from under a rock evolved a group of new console dev’s. And then a PM. The journey to modernity had begun … again! WE’RE BACK! AGAIN!

  1. Support kernel namespaces and cgroups (for Docker, headless Chrome, ...)

    Kernel namespaces are a Linux feature that enables sandboxing (used in things like headless browsers) and containerization (i.e. Docker).

    It would be great if WSL supported those scenarios.

    • Run WSL binaries in Windows without 'bash.exe -c'

      It would be nice for Windows to be able to run binaries in WSL without needing to prefix 'bash.exe -c'. The main reason for this would be editor integration. For example, VS Code language extensions require the binary for the language to be in your PATH and often do not work without it. It seems like a waste to install the language in both Windows and WSL just to get editor integration.

      Obviously, executables from Windows will still have a higher priority. Only when the executable cannot be found in the Windows PATH should it now attempt to run the…

      • Add: SQL Server database support for WSL

        I am using Ubuntu bash in Windows 10 falls creator update. I am so in love with it, I went ahead and created multiple .NET Core applications, including MVC web apps in Linux. Now what I am missing is support for Native SQL Server database in WSL. I want to use the WSL as a self contained Dev environment for .NET Core development in Linux without bothering about having another Linux VM or so.
        Please add this feature so that we could at-least install SQL server developer edition in WSL and can build great data driven apps.

        • systemd-nspawn containers need cgroups

          Windows Subsystem for Linux is one of my favorite Windows 10 features. But when I am trying to set up a special Linux environment with lots of compiled-from-source programs and dependencies, I'd rather not clutter it all up for everything else I want to do. The systemd-nspawn containers seem like a good solution. (I also see other ideas for LXC and Docker.) But when I try to use it, I get this error:

          failed to determine whether the unified cgroups hierarchy is used: no
          medium found

          I asked the systemd people if there's any way to fix this. They said,…

          • Add possibility to Add Bash to Quick Link Menu (Win+X)

            Please add possibility to add bash to Win+X Menu. Or if you want to be consistent with current approach Add option under Settings -> Personalization -> Taskbar -> "Replace Command Prompt with Bash on <distro> on Windows in the menu when I right-click the start button or press Windows key+X"

              • Make the Windows FS mounts under WSL have reasonable user and group

                Right now the WSL suffers pretty severely from /mnt/c/ and others having all the files owned by root:root and permissions set to 777.

                A *LOT* of tools will refuse to work with files with those permissions, files owned by root, or under the root account for security reasons. Some quick examples for developers: git and hg (Mercurial)

                • vaapi / vdpau support for hardware video decode/encode acceleration

                  Command-line tools such as ffmpeg or gstreamer that deal with video can optionally use hardware acceleration for various codecs, depending on GPU support -- see https://trac.ffmpeg.org/wiki/Hardware/VAAPI

                  It would be great if the hardware acceleration for video already supported by Windows native drivers could be exposed via VAAPI and/or VDPAU interfaces to be used.

                  • fcntl(F_SETFD, 0) failed:Invalid argument

                    After installing cpanm with sudo apt install cpanm, attempting to install Server::Start with

                    cpanm Server::Starter

                    hangs on an infinite loop:

                    stat("/tmp/DyfOTwwiZ6", 0x953298) = -1 ENOENT (No such file or directory)
                    time([1512700980]) = 1512700980
                    nanosleep({1, 0}, 0x7fffdde1f360) = 0
                    time([1512700981]) = 1512700981
                    stat("/tmp/DyfOTwwiZ6", 0x953298) = -1 ENOENT (No such file or directory)
                    time([1512700981]) = 1512700981
                    nanosleep({1, 0}, 0x7fffdde1f360) = 0

                    This appears to be caused by the child process in the test dying because an fcntl call fails. To get more information, you can run

                    sudo cpanm Server::Starter --look

                    then typing

                      • Would love to have MTR support

                        MTR is a very useful tool for Ops people. I would love to not have to fire up my Ubuntu VM to be able to run mtr.

                        Currently I get "mtr: unable to get raw sockets." when attempting to run it.

                        • Assign groun `tty` to all /dev/ttyS* with read/write perssions

                          At the moment, a user is required to run an elevated command to access any of the new /dev/ttySx serial devices, or they are required to assign a group (or user) access to the serial device.
                          Any assigned permissions on /dev/ttySx will be reset to root:root with owner rw only when the bash.exe is closed and re-opened. Which can be come frustrating with automated scripts

                          I propose that WSL will assign the group `tty` (or `dialout`) to the serial devices. So that a user may add themselves to the group once and consistently have access to the serial devices without…

                            Powershell is a pain to use for non .NET developers, and having to play around with configuration via menus is very tedious.

                                    • enable nfs mount for BASH for windows

                                      If we can mount remote fs on the windows machines that would be great , Please help us get past putty and other ssh clients

                                      • OpenCL & CUDA GPU support

                                        It would be nice to have (relatively) easy access to the dedicated GPU's on our Win10 PC's, and OpenCL support for the AMD Drivers & CUDA for NVidia drivers etc.

                                        What I am thinking on specifically (although there are many many uses for it and CUDA support) is hashing functions that are lackluster within windows itself, but benefit immensely within Linux and Unix.

                                        Cryptocurrency mining for example, is known to be much faster on Linux systems than Windows. Do you see any support for OpenCL and/or CUDA in the future?

                                          It’s on the backlog, but not currently planned.

                                          We know many of you would like to be able to accelerate your numerical analysis code via CUDA/OpenCL, etc.

                                          One thing to explore in the meantime is to try running your code in Windows. Windows actually has very powerful GPU-acceleration capabilities and you may well find that much of your existing code may well work already or require trivial effort to port to Windows itself.

                                          in the meantime, bear with us, and UPVOTE THIS ISSUE if you care (please don’t create another duplicate ask – that doesn’t help us prioritize asks).

                                          Thanks.

                                          Since shortcut settings are opaque, it can be very annoying to keep multiple terminal programs in sync. It would be nice if we could set a console to the settings we have stored in Default with one-click / command.
