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. 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…

    • Add USB Device Support

      This ask is specifically for adding USB Device support to WSL - i.e. exposing USB busses and devices to the OS.

      This is NOT an ask for adding the ability to communicate with external USB peripherals like phones, IoT boards, etc. - those asks are elsewhere:

      • 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.

          • Make core dump files available in WSL

            When a process crashes on WSL it does not generate a core dump, even if the necessary configuration is in place.

            This is critical for debugging complex issues during development.

            • Support kernel namespaces and cgroups (for Docker, headless Chrome, ...)

              Kernel namespaces are a Linux feature that enables sandboxing (used in things like headless browsers) and containerization (i.e. Docker).

              It would be great if WSL supported those scenarios.

              • 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.

                • Would love to have MTR support

                  MTR is a very useful tool for Ops people. I would love to not have to fire up my Ubuntu VM to be able to run mtr.

                  Currently I get "mtr: unable to get raw sockets." when attempting to run it.

                  • 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.

                    • Windows Console options mockup

                      Mockup: https://imgur.com/LjRKwIZ
                      Some ideas that could be added in Windows Setting about the Windows Console:
                      Select a new default shell: Allow user to select PowerShell, Command Prompt or Bash as default shell across the system
                      Reset Windows Console options: Reset all users customizations in Console>Right Click> Default & Properties windows.
                      Apply following settings to Windows Console:
                      - Use legacy console (As in Console Properties window)
                      - Various edit options
                      - Command History settings
                      - Font settings
                      - Text selection
                      - Transparency (View better transparency option on uservoice)
                      - Etc

                      Maybe can be added a section dedicated to Windows Console

                        • Add Wireless Device Support

                          iwconfig and other wireless device tools cannot interact with wireless devices. While ifconfig, ip, etc network support has been added and displays the wireless devices (wifi0, wifi1, ...), iwconfig and other tools cannot detect wireless support. Considering the omnipresence of wifi, this makes the "Enable network connection enumeration" request feel technically fulfilled but practically half-done. Can we expect wifi support in the near future? Or are there work arounds involving the installation or compilation of particular tools?

                          • 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…

                                    • Support gpg2 smartcard integration (yubikey)

                                      Don't see a way at present to use a yubikey/smartcard inside WLS. Seems like this would require USB support in order to integrate directly. Only workaround at present is to SSH into WSL and forward the ssh key, which makes the ssh-agent available to WSL, but still not the gpg-agent.

                                      • Linux like mouse click selection and copy/paste

                                        In *Nix systems we can drag select text. Alternatively double left-clicking will smartly select a word/path (etc) boundary. Clicking for the third time selects the entire line. In all instances above it will auto copy to the selection to the clipboard.

                                        Whilst we have some slightly better options with Quick edit and insert mode there's still some subtle differences than the experiences above.

                                        Can we more closely mimic this behaviour?

                                        • 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.
