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. WSL raw socket support for ethernet to allow for nmap functionality

    Can not run nmap from WSL due to inability to interface with network sockets. Please enable passthrough or provide documentation / support to allow configuration of ethernet sockets to work with nmap. Was lead here by this discussion: https://github.com/Microsoft/WSL/issues/2039

    • 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.

      • Support native Docker daemon (dockerd)

        It would be great to be able to run the Docker daemon (dockerd) natively in WSL.

        Thanks for already adding support for running the Docker client in WSL.

        • 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.

          • Support iptables

            Originally posted on Github around a year ago: https://github.com/Microsoft/WSL/issues/767

            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.

            • Support Oracle Berkeley DB and lmdb

              Both Oracle Berkeley DB and lmdb fail on WSL as of build 18204. This is due to an issue with mmap described at https://github.com/Microsoft/WSL/issues/658 and https://github.com/Microsoft/WSL/issues/902

              Please fix the mmap issue so that lmdb and Oracle Berkeley DB, and projects relying on them, work in WSL.

              • 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

                  • 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?

                    • 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

                              • Use WSL as Linux VM for Docker for Windows

                                "Docker for Windows" would greatly benefit from using WSL instead of their ever failing MobyLinuxVM.

                                https://github.com/docker/for-win/issues/267#issuecomment-449234581-permalink

                                Perhaps you may assist the "Docker for Windows" team in migrating away from their malfunctioning Linux VM towards utilizing WSL.

                                • Add support for other Linux distros / meta-distributions - part two

                                  After about year we have some distros in official MS magazine but we already don't have rights to install another Linux distributives.

                                  I think we need to general methods of porting yourself distros to WSL.
                                  It's will be easy to another people - the one idea to be popularity.

                                  • 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.

                                    • 😡 Please drop the name "Linux" until you actually implement the full Linux kernel

                                      You lured people into WSL thinking the devs are not needing the full kernel.

                                      But many people asked for the full linux kernel features.

                                      Until you make it full kernel abi and api compatible, please drop the name Linux from WSL!!! 😡😡😡

                                      • 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

                                        • Map WSL process ID to Windows process ID

                                          Currently there appears no clean way to get the corresponding Windows process ID of a running WSL process. I can inspect the PIDs of running processes in Windows taskmanager or with the tasklist command from bash on WSL as in:

                                          oeffner@grove:~$ cmd.exe /c tasklist

                                          But that does not guarantee unambiguous identification PIDs if more processes have the same name.

                                          It would be great if the PID of a WSL process was available as an additional column for Windows TaskManager and the tasklist command.

                                          It would also be great if it were possible under WSL to get the corresponding Windows PID…
