Command Prompt / Console / Windows Subsystem for Linux (WSL)

Greetings from the Windows Command-Line Teams, including the Windows Console and Windows Subsystem for Linux (WSL) teams!

We’re hear to learn about the features you’d like to see in the Windows Console (the terminal app itself), Cmd and PowerShell shells, and the Windows Subsystem for Linux (WSL) upon which several Linux distros now run!

Note: Please don’t file bugs & issues here: file issues on our GitHub repos instead:

Please DO post your asks, ideas, wants and needs for future features: We ARE listening, and we ARE grateful for your feedback!

  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?

      Hey WSL users, as many of you have been asking for an update: we still do not have anything on the books yet for this feature, but we have NOT forgotten this request.

      As we navigate requirements and evaluate our WSL work, we ask that you please continue voicing your desires and upvoting this issue. Feel free to ping me on twitter @CraigWilhite to tell me more about how you’d like to see this feature in WSL.

    • 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.

      • 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

        • 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.

            I have a multi-boot laptop, and would like to mount my xfs / extn / etc. partitions and boot to linux only when needed.

            • 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…

                • 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.

                  • 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.

                    • 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.

                        ...or at least to /dev/sda? (disks) block devices. It could be very powerful to run things like
                        dd if=/dev/sda2 of=some-remote-mounted-volume/my-backup-C.img

                          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 ;)

                        • 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

                                I want to point out that we have very clear that WSL does not support X/GUI desktops, apps, and tools.

                                This said, we totally understand the utility of audio support in several scenarios. While this is not currently a high priority for us, it’s something we’ll definitely consider for the future.

                                If you’re interested in accessibility & screen reader support, we’ve actually exposed the contents of the Windows Console to UIA for the first time in Fall Creators Update, allowing Narrator & other screen readers to read command-line output more easily: https://blogs.msdn.microsoft.com/commandline/2017/10/11/whats-new-in-windows-console-in-windows-10-fall-creators-update/

                              • 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.

                                  • Support for running systemd

                                    Not to replace the current WSL init, per se, but it would be very useful to be able to run "systemd --system --unit=foo.target" as a way to set up and manage sets of services/daemons required for particular development, etc., configurations.

                                      Not sure how feasible this is to implement, but I've found myself in a couple of situations where it would've come in quite useful.

                                      • Offline installer for bash

                                        It needs to be possible to install bash offline.

                                        There are a thousands of us who'd kill to be able to use bash on Windows machines attached to classified and other machines that are offline, and can't ever be connected to the Internet for any reason.

                                          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.

                                        • Raw Disk access and filesystem mounting

                                          I would love to have the ability to access raw partitions on my hard drive (provided that WSL is stable and will not obliterate my data) and also have the ability to mount filesystems not natively supported under Windows such as ext4, and btrfs among others. Specifically, I want to be able to mount partitions on my hard drive that I have windows installed on.
