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. Andoid Distro Support

    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.

    • 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,…

      • 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?

        • ConHost should support OTF fonts

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

          • /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.

            • relocate Temp folder

              for person using SSD and have a large memory (for example, I myself), it may be better to relocate "Temp" folder to another location (e.g., just put them into RAM-disk)
              but either using mklink/j or mklink/d will got an error 0x80070057 or 0x80070780 or something like that.
              it there any method to relocate Temp folder?

                • 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…

                    Don't just use Linux, but support the running of other OS such as FreeBSD, NetBSD, and OpenIndiana, not on WSL but another subsystem.

                    • 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.

                            • Add Posix ACL support to WSL and for drvfs mounts derive them from Windows ACL

                              Add Posix ACL support to WSL and for drvfs mounts derive them from Windows ACL. It is possible to map Posix ACLs to Windows ACLs with some limitations. That would greatly enhance interoperability between windows applications and wsl applications. Using metadata to save posix permissions on drvfs mounts greatly reduces interoperability, since windows applications are not aware of posix permissions saved as metadata.

                                • Wrap a DLL as a .so

                                  If you provided a wrapper for DLLs to expose them as Linux shared object files, WSL programs could call into them to execute functions that use Windows drivers.

                                  The example I have in mind is that my Python code, running in WSL, could load one of these wrapped DLLs posing as a .so file, and execute code that makes CUDA calls running against the native OS drivers.

                                  • Libsixel support for CMD/Powershell/WSL

                                    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.

                                    • Make the per-directory case sensitivity flag (CaseSensitiveInfo) inherited to new child directories

                                      I'm experimenting with moving my web development environment from MacOS to Windows 10. I wouldn't have considered the possibility a few years ago, but WSL and related linux compatibility improvements are looking really great! Unfortunately I have run into a bit of a sticking point around file system case sensitivity.

                                      Since my projects require a case sensitive file system (deployed to linux servers) I was happy to learn about the new per-directory case sensitivity flag. The feature seems to be only partially complete though. Cloning my projects via git in WSL worked perfectly and all the directories were created with…

                                      • Add Windows Hello(e.g. fingerprint) support to WSL

                                        Please add Windows Hello support for WSL, so that we can use fingerprint rather than enter root password in WSL

                                        Thanks

                                        • 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.
