Command Prompt / Console / Bash on Ubuntu on Windows

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.

        Updated the title to reflect the ask.

        This first release of Bash/WSL doesn’t support background tasks, cron jobs, daemons, etc. Currently, when you close your last bash shell console window, we tear-down the Linux process chain in order to conserve resources.

        We are looking at the ability to run background tasks/daemons/cron jobs in future releases.

      • bash copy paste

        Keyboard-based copy/paste should work in the bash console (ctrl+c/v)

        • 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.

            • Please add 32 bit ELF support to the kernel

              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!

                • 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

                  • 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.

                    • 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…

                                  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.

                                  Eg, when dragging folder "C:\Users\Alice\Documents" and dropping it into a bash window, paste the following:

                                  "/mnt/c/Users/Alice/Documents"

                                  • Symlinks and pathing.

                                    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 support for other Linux distros / meta-distributions

                                        Consider adding other distros and/or meta-distros e.g. Gentoo ( https://www.gentoo.org/ ) - a mature and well supported metadistribution.

                                        The hot keyword here is "meta": that's mean it's a unix (posix) distribution that could run on virtually any *nix kernel.

                                        Porting it to Windows lxss should be a child's play!

                                          We’ve just announced that in addition with our continued work with Canonical, we’re working with SUSE and Fedora to bring distro’s to the Windows 10 Store, and to WSL in the Win10 Fall Creators Update (fall 2017).

                                          https://blogs.msdn.microsoft.com/commandline/2017/05/11/new-distros-coming-to-bashwsl-via-windows-store/

                                          Keep your eyes on this thread and my Twitter account (@richturn_ms) for more news on this front.

                                          And … yes … we plan on opening this up more broadly afterwards to support community distros etc.

                                        • 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…

                                            We agree; our branding is not simple, but it’s worth noting that neither is our situation:

                                            WSL is the name of the Windows Kernel infrastructure that installs, loads, executes, and manages ELF64 binaries. It’s important to note that it’s a key goal that WSL remain distro-agnostic.

                                            Note that, until you run Bash.exe (part of WSL) for the first time and download and install Ubuntu, there IS NO Ubuntu anywhere on your system!

                                            Now, referring to the user-mode tools delivered as a packaged distribution as WSL would also be inaccurate and misleading. This is why, when we’re talking about the user-facing experience – the thing that you actually interact with – we call THAT thing Bash on Windows … because we went through every other permutation and idea and couldn’t come up with anything as recognizable, comprehensible, or “short”, even though I think it’s still too long!

                                            Typically, when referring…
