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. 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.

    • Consider enabling cron jobs, daemons and background tasks

      Bash/WSL doesn't support cron jobs, daemons or background tasks in Win10AU. The ability to run background jobs would be very useful. Please consider adding this feature.

      • Add FUSE (Filesystem in Userspace) support in WSL

        Please add FUSE (Filesystem in Userspace) interface /dev/fuse into WSL (Windows Subsystem for Linux).
        With FUSE, we can access from WSL to file storages regularly used with Linux cluster environments such as GlusterFS, Moose FS, etc.

        • Let us right click "open bash here" from explorer

          Similar to how you can shift+right click and "open command window here" while viewing a folder through explorer. It would be nice to have "open bash here" as well.

          • Support AF_PACKET address family (tcpdump/wireshark...)

            From https://github.com/Microsoft/BashOnWindows/issues/1628

            It would be great to get support for AF_PACKET, as some networking tools or software rely on that.

            Samples of tool that won't work without it:
            - tcpdump (socket: Invalid argument)
            - wireshark
            - some nmap functions
            - Scapy

            • Please enable WSL to run 32 bit ELF binaries

              It seems that executing 32bit ELF binaries results in "Exec format error" - guessing the kernel doesn't have 32 bit emulation support (compilation is fine, but precompiled binaries don't run). A vast number of legacy programs are still 32 bit, please add support if it won't completely destroy everything in the process - thanks!

                • Filesystem slow compared with native Ubuntu system.

                  http://www.phoronix.com/scan.php?page=article&item=windows-10-lxcore&num=1

                  Lists some benchmarks across Ubuntu and this subsystem. It is very competitive with Native Ubuntu Linux, except when it comes to filesystem access.

                  Filesystem access is important for compilation, as well as the thousands of "watcher" js and ruby programs that constantly touch the filesystem, which are the stated target market.

                  So, find a way to speed that up. (I don't know how you are currently mounting the filesystem, so I can't offer any ideas, other than removes as many layers as possible to the filesystem.)

                  If you are using the ntfs systems in Linux, you might consider implementing…

                  • Alternate install location option would be nice

                    Currently the only place the linux lxss folder can be located is inside the user's user profile directory. It'd be nice to be able to put this folder anywhere on any drive for those of us with small SSD c: drives.

                    • Make WSL filesystem accessible from Windows

                      Access to the Windows filesystem from WSL is easy enough. Now we need access to the WSL filesystem from Windows.

                      • Access to "real" linux devices in /dev

                        ...or at least to /dev/sda? (disks) block devices. It could be very powerful to run things like

                          Related to “Add USB Device support”: https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/16759696-add-usb-device-support

                          This is a common ask and, now that we’ve gotten through most of the fundamental engineering, we’ll be more able to start looking-into device support sometime relatively soon, though no guarantees about when and what ;)

                        • A file created in C:\Users\<user>\AppData\Local\lxss\root from Windows isn't visible in WSL

                          I would like to be able to create files in the WSL root directory using Windows tools (VSC, NotePad++...)

                          I can modify files there (e.g. .bashrc) but if I create new files they are not visible from the WSL side.

                          • Run services when Windows starts?

                            In Bash, I can set services to boot on startup with something like this:

                            sudo systemctl enable application.service

                            However, it would be really handy if certain Bash services started when Windows started. (especially for web servers, database engines etc.)

                            I know the way Windows and Linux does services is quite different but as an example, it would be great if I could start Windows and know that my local MongoDB server is all fired up and ready to go.

                            Would love to know other peoples thoughts on this and if it's at all feasible?

                            Thanks, Anthony

                                  Hey all. Thanks for posting this ask: Its something we hear on a semi-regular basis.

                                  We understand and appreciate many of the scenarios in which one might want to install a Linux distro offline using a previously downloaded/acquired image. However, we just didn’t have cycles to handle this request in the Win10AU release.

                                  It’s on the backlog and we will consider for a future release.

                                      Currently getting "Operation not permitted" with ln -s (which I believe is due to a filesystem incompatibility). Also it would be phenomenal to see slash paths adopted across the filesystem.

                                      • Add libusb support to WSL

                                        Since previous one(https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/16759696-add-usb-device-support) was marked "complete", this one more clearly states support for libusb as in any usb device raw, rather than just storage mounting and serial pass-through.
                                        My example need is Yubikey gpg-card.

                                        • Unify Branding

                                          Right now, the branding for this feature is kind of all over the place:

                                          - Windows Subsystem for Linux
                                          - Bash on Windows
                                          - Bash on Ubuntu on Windows

                                          I realize that WSL is probably, strictly speaking, a separate feature/team (I'm guessing), from BoUoW; and that BoW is probably the same thing as BoUoW, just shorter ... however, the fact that they are all used interchangeably in official blog posts and documentation can be quite confusing when a) searching for information, and b) when communicating about the feature to others.

                                          I'm sure there are reasons for this, including internal team…

                                            Now that we’re delivering multiple distros via the Windows Store, we’re beginning the transition the branding of this feature to just WSL from “Bash [on Ubuntu] on Windows”.

                                            In the future, instead of running “Bash on Ubuntu on Windows”, you’ll just run Ubuntu or openSUSE, or SLES, or Fedora, etc. and they’ll run on WSL.

                                            We’re updating our docs and will start to transition our messaging over the coming few months.
