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.

    • Support tabbed interface

      Great to see some of these improvements, especially the cut/copy/paste keyboard shortcuts. However, I've been seeking for a way for the cmd window to have a tabbed interface for a while. So, for example, I can run a ping/tracert etc. in one tab, a chkdsk in another tab, and something else in a third, without having multiple windows open taking up screen real estate.

      Also consider adding panes side-by-side within the console.

      • 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.

          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.

                  As Chip said, UTF-16 is rather baked into the stuff we do. The console host does use UTF-16 somewhere in there. :P We just have the matter of dealing with code pages throughout the history of computing existence that causes us heartburn every time we think about how to fix this. :( It’s definitely something that we would like to look into on our backlog.

                • 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!

                    • 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.

                            Yep, this would be really cool. Not just for URLs, but things like paths too. Script emits a path to an error log? Just ctrl+click it to open!

                            I can see some trickery around the parsing (performance impacts? security? and of course the parsing itself…) and the launching of another app (security again?). But it would be awesome.

                            It’s on our backlog for sure.

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

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

                            - tcpdump (socket: Invalid argument)

                            • 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 "sudo" tool/command in cmd/PowerShell

                                      On *nix you can run a command from a non-root shell, which is the equivalent of a non-administrator Command Prompt, with administrative privileges, similar to what UAC does when it asks a user if they would like to give an application administrative privileges. To disable a network adapter, for example, you can run "sudo ifconfig eth0 down". The prefixed "sudo" command will run "ifconfig eth0 down" with what is essentially administrator privileges in Windows. Currently you have to do some long-winded (long-typed?) "runas", which requires that a username and password are provided. I don't necessarily need Command Prompt to always…

                                      • Global hotkey to activate/deactivate running console window.

                                        It would be great if there could be a global hotkey to activate and deactivate the console window.

                                        This is also called a "quake style" command line, similar to the console in Quake games.

                                        For example, if I have the console running in the background, but my current focus is Visual Studio and I hit Ctrl+`, it should activate the console window by making it the current focus. Hitting Ctrl + ` again would make Visual Studio the focus.

                                        iTerm2 on the Mac has this and it's my favorite feature.

                                          You will be Rich’s best friend forever. He loves the idea of a Quake console as well and talks about it all the time. :P I know for sure this is in our backlog already.

                                          Some of the suggestions like persistence and multiple sessions and whatnot seem related to the “history between sessions” and tabs/multiplexing ideas. Same technical challenges apply, but sounds possible at some point. :)

                                        • Transparency enhancement

                                          Transparency is a nice visual enhancement, but it should only apply to the window contents and not the surrounding "chrome" of the window, such as the title bar and scroll bar. Also in the settings dialog, the slider should indicate the percentage of transparency that it is set to instead of blindly guessing at what point on the slider is ~70% or whatever the user finds preferable.
