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. 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.

    • Inter WSL communication

      Since we can install different flavors of GNU (Ubuntu,Kali...), it would be great to be able to communicate between them in a simple way; eg to transfer keys, configuration files, etc, eventually to share folders through symbolic links.

      • Allow refs to be mounted with metadata

        Since the last year I've been using ReFS a lot to store my data and I loved it so far. I am unable though to use apps that rely on different ownership of files that are stored in my ReFS partitions and especially those that won't run as root.

        In order to do so we need metadata option when mounting ReFS volumes to perform simple chown operations.

        Please consider implementing this for ReFS as well.

        • 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,…

          • Add a stat()-like API to Win32 to access WSL file attributres

            Git for Windows currently runs into problems with file attributes if you have a repo that you use both with WSL (under /mnt/c) and native Windows tooling. If it was possible to set and get Unix file attributes from Windows, it would make interop easier. This would be similar in spirit to the AF_UNIX socket support that was recently introduced.

            • More general console color tool

              The current version of console color tool on GitHub has a very limited range of usage. It can only change colors of cmd and Powershell but not of WSL or other console programs.
              The color tool should be integrated with the console properties so that we can easily change colors of WSL or any other console programs.

              • Option to change location of wsl

                By default wsl is installing to the system drive. In much cases this is an SSD with less space than a second drive like a normal hdd with much more space. If you use wsl for development of a Website or try to use WSL with an x-server for windows much space is needed to take advantage of it. So there should be an option to move the wsl and all files containing to a drive where an user has much more space than on it's system drive by default.

                  • Upgrading WSL to the new Ubuntu 18.04 LTS, and some comments & suggestions.

                    I've been using WSL on Windows 10 laptop for well over a year now, and have been relying on it so much for local development of my Linux work, that it's been months since I last booted into the Linux partition.

                    I know that if I'm doing any low-level work, I may have issues, but so far, my experience has been great. Whatever I write on WSL, as long as it passes my gtest unit test cases, I can be sure that it will also work on other Linuxen.

                    I've been using apt to install new packages, and Xenial Xerus…

                    • _write fails to write non-ASCII characters to console(fd=1,2) after setlocale(LC_ALL, ".utf-8");

                      SetConsoleOutputCP(65001);
                      _write(1, u8"ENU中文\n", 10); // succeeds
                      setlocale(LC_ALL, ".utf-8");
                      _write(1, u8"ENU中文\n", 10); // fails
                      ----
                      Probably because the internal function 'write_double_translated_ansi_nolock' assumes that setlocale only supports SBCS/DBCS but not UTF-8, which is no longer true in RS4.
                      The code file: C:\Program Files (x86)\Windows Kits\10\Source\10.0.17134.0\ucrt\lowio\write.cpp

                        • ReadConsoleA & ReadFile & 'type con' fails to read non-ASCII chars when code page is 65001

                          Note: ReadConsoleW works because it is 'code page-independent'. WSL works because of some internal workarounds.
                          Re-inventing the wheel which is an iterator translating UTF-16 to UTF-8 each individual project is rather boring.
                          This annoyes me a lot since I was interested in using UTF-8 in Windows console.

                          • /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.

                                maybe it's just a matter of priority coz i'm sure it's not technical as others are able to install Fedora on WSL using a long way.

                                request to add Fedora in the Store please.

                                    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?

                                    • An uninstall question no one seems (so far) able to answer

                                      How do I uninstall the openSUSE distro while leaving my Ubuntu distro installed? I can't seem to find an answer to this question.

                                      • 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.

                                        • 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.
