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.

            • 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.

              • 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

                    • 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.

                      • 😡 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!!! 😡😡😡

                        • 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.

                            • 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?

                                  • Open bash in current folder from context menu

                                    I would love a right-click option in a folder to open the current folder in a WSL distro. right click to open in the folder C:\Users\account would open a terminal in /mnt/C/Users/account

                                      • wslpath should return \\wsl$ path

                                        Currently wslpath rejects path inside VolFs.

                                        • Recursive file case sensitivity?

                                          Can we get folder recursive case sensitivity? You've very recently added it with:
                                          fsutil.exe file SetCaseSensitiveInfo C:\folder\path enable
                                          what do we have to do to get full directory case sensitivity?

                                          It's really confusing as to why this isn't implemented yet when NTFS has supported it forever and windows 10 has no more kernel excuse...

                                          Is something like this necessary?

                                          [string] $PathRoot = 'folder here'

                                          [bool] $EnableCaseSensitivity = $true

                                          @(Get-ChildItem -Path $PathRoot -Recurse -Directory | Select-Object -ExpandProperty 'FullName') | ForEach-Object {
                                          cmd /c ('fsutil.exe file SetCaseSensitiveInfo "{0}" {1}' -f ($_,$(if($EnableCaseSensitivity){'enable'}else{'disable'})))
                                          }
