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. 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.

    • Add support for 32-bit ELF executables

      A lot of tools written for Linux can be downloaded as 64-bit, but there are still a few that only 32-bit downloads are available for. I've tried using virtual machines, but that tends to not be feasibly in some projects.

      • Add libgl support to WSL

        There are many development tools unable to be ported to Windows due to their proprietary nature and others that though not proprietary have no interest in porting to Windows. For me specifically, it's being able to utilize dev tools such as VSCode, Sublime Text, Draft, Javalin, Bootsnap, OSQuery, and/or FSQL without downloading a third party X server that only does partial implementation. Libgl is specifically required to get GUI apps to run and doesn't currently exist. Please implement libgl and create an API for driver makers to use to enable use of these and other GUI dev tools.

        • To be able to open tabs would be great.

          I am stuck using a MAC at work because the terminal is far superior. with Linux/MAC I can open multiple tabs in the terminal, with windows WSL I have to open a bunch of windows. Sometimes I will has 7 or 8 tabs open at once... Adding tabs to the command terminal would be an excellent upgrade. I work with a bunch of DevOps and TechOps people and the vast majority would rather be using windows, but because of the lack of features with the command box they are stuck using MAC's

            • Backup/Restore/Share/Snapshot a WSL installation

              Backup / Restore / Snapshot a WSL installation.

              For development puproses it would be very nice to ba able to backup a WSL installtion and to resore it on the same or another(!) PC.

              Provide a means of 'going back' (like a VMware snapshot) when a WSL installation became unstable, bloated, corrupt.

              BTW is there a way to have more than one Ubuntu installations at the same time?

              Best regards.

              • Allow WSL root folder location to be in a separate EXT4 partition recognized by windows

                The idea is basically allowing the user to actually play with the files in a GUI environment with all the added perks of an explorer window.

                    • A command to confirm that linux is running on WSL

                      There are many cases where it's useful to programmatically check whether linux is "regular" linux or WSL linus. E.g., in Python calling `sys.platform` just returns `linux`, not `linux-wsl` or something like this. It'd be helpful if there were a command line argument that could reliably confirm that the platform is WSL.

                        • Upgrading WSL to the new Ubuntu 18.04 LTS, and some comments & suggestions.

                          I've been using WSL on Windows 10 laptop for well over a year now, and have been relying on it so much for local development of my Linux work, that it's been months since I last booted into the Linux partition.

                          I know that if I'm doing any low-level work, I may have issues, but so far, my experience has been great. Whatever I write on WSL, as long as it passes my gtest unit test cases, I can be sure that it will also work on other Linuxen.

                          I've been using apt to install new packages, and Xenial Xerus…

                          • Have dev/shm actually use RAM instead of system drive

                            dev/shm appears to be using disk space as creating objects there decreases available space and IO speed is significantly limited.

                              • Add a Win32 API for escaping/unescaping WSL paths with forbidden characters (e.g. : ? *)

                                It is possible to create files in WSL that have characters in them that are not supported in windows (:?* etc.) and these are dutifully escaped to valid UNICODE sequences in NTFS. However, what is lacking in Win32 is a function that takes a (possibly) escaped UNICODE path and converts it to the UTF8 sequence that a WSL process sees, and back again. For example, a git repo with files containing characters that are unsupported in Windows (not too uncommon) will only be possible to work with in WSL - Git for Windows will see the WSL paths as deleted,…

                                  I'm very happy about Ubuntu / SUSE / Fedora options for WSL. But isn't Android based on Linux as well? It would be AMAZING to be able to test/run Android apps using WSL, as other Linux apps are able to run GUIs in Windows in the current version.

                                  • /proc/sys/fs/file-max does not exist

                                    I am attempting to run a bioinformatics pipeline using WSL. This pipeline relies on information within /proc/sys/fs/file-max.

                                    On standard Linux distros, this file is a plain text buffer containing an integer. WSL does not appear to have this file.

                                    [error] On machine: **omitted**, /proc/sys/fs/file-max does not exist.

                                    Reproduce by running the following command on WSL and compare to a Linux system.

                                    $ cat /proc/sys/fs/file-max

                                    File does not exist.

                                    A plain text buffer containing an integer should be present.

                                    • Easier way to reinstall WSL distros

                                      Request: An easier way reinstall distros.
                                      it was previously possible to do it with lxrun, but now with wslconfig it is more manual

                                      When experimenting I break my installs a lot and want to get back to a clean start.
                                      Previously i could run
                                      lxrun /uninstall /full /y ; lxrun /install
                                      Which would blow it away, and then put it back on.

                                      But now according to the docs at https://docs.microsoft.com/en-us/windows/wsl/wsl-config
                                      You now run
                                      wslconfig /unregister <DistributionName>
                                      and then need to go back into the windows store and manually install it again.
                                      An automated way to do it like we could…

                                      • Making DrvFS fmask=111 usable

                                        (from https://github.com/Microsoft/WSL/issues/3267)

                                        At the moment when using a git repo on DrvFS, all new files will be created as +x, which git detects and sets core.filemode=false. Enabling fmask=111 in drvfs options fixes this, but that breaks all .exe interop, since those need the +x bit too.

                                        As mentioned in the WSL bug, this can be worked around by adding an explicit mount with the options in fstab, but those entries are not auto-mapped when invoking `bash.exe` or `wsl.exe` from windows, meaning either you need to manually mount without fmask any PATH entries and re-write the WSL-side mapped paths, or…

                                        • Block device support for embedded systems

                                          I would like to be able to build the yocto project for embedded Linux natively which is possible currently. However I am unable to dd to /dev/sda to deploy it to the target because It is an external block device. Do we know if this will ever be supported?
