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!

    • Optimize disk I/O speed

      Due to administrative requirements, I cannot disable windows defender in the WSL directory - right now, all disk I/O is **very** slow (10x slower than native windows) - is disk I/O already fully optimized? 5-10x slower sounds pretty bugworthy.

      • ConHost should support OTF fonts

        More and more fonts are OTF rather than TTF (e.g. nerdfonts.com)

        • WSL add ability to scroll up

          In the WSL you should be able to scroll up and see your previous sessions commands/output (much like you can with cmd). Currently you only get what you can see on the screen, forcing you remember to pipe everything to less.

          • Support wsl --import gzipped tar file

            wsl --import now supports only plain tar.
            But, WSL Distro in MS Store contains gzipped tar file.
            tar.exe could not extract a tar file from tar.gz.

            • Mount filesystems permanently from /etc/fstab

              It's great that I can mount file systems or USB devices through drvfs but these mounts don't persists when all Linux shells are closed.
              How does one mount filesystems permanently, say through /etc/fstab ?
              Surely it shouldn't be necessary to manually mount filesystems after the last Linux shell has been closed and a new is invoked.

              • 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:

                • 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.

                    When I pipe console.log("hello it’s time"); or simply type it, it gets mangled. This also happens in PowerShell (I presume because it uses the DOS commands

                    • 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…

                      • 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.

                        • 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.

                            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?

                            • Support ctrl+c signals for windows applications launched from WSL/bash

                              In short: Make ctrl+c interrupt / kill windows applications launched from WSL.

                              In long: At the moment windows executables launched from bash / WSL do not terminate when I ctrl+c the process. For example I might launch a compilation step which uses a windows .exe, and then decide to cancel it and modify something first. After ctrl+C the bash terminal thinks the process is stopped and lets me begin typing new commands, but the compilation keeps running and spills output into the terminal. Any file locks etc. will also be held which might block further commands I want to execute.…

                                  I would like native libsixel support as the only current way to run it is as per this comment https://github.com/Microsoft/WSL/issues/1099#issuecomment-248513013. If possible, this support would be for for all terminals. This would prove extremely useful in performing quick research without having to leave the terminal.

                                  • Kernel thread creation is not working in WSL

                                    Yesterday I was in my operative system class, and we were studyng about user and kernel thread creation.

                                    The user thread example ran well, using the pthread library in C. But when I ran the kernel thread example, it failed and I couldn't create the thread. For that example we used the macro clone in library sched.h

                                    I'd be good if WSL could support that type of thread creation.

                                    • 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,…

                                      • Bridge to Windows ssh-agent service

                                        At the moment I'm using putty on Windows together with its pageant tool, and inside WSL I use https://github.com/vuori/weasel-pageant , wich simply implements a bridge from inside WSL to use the pageant running on Windows.

                                        Switching from putty to Win10 builtin ssh and ssh-agent service makes this unavailable. Would be great to be able to reuse the Windows ssh-agent service from inside WSL, so I only have to store my key(s) in one safe place on Windows.
