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. WSL2 to simplify running linux containers on Windows

    Right now I am running docker containers on an Ubuntu virtual machine with Wireguard enabled, and that VM itself runs on Hyper-V. I am wondering whether WSL will

    - be supported on Hyper-V,
    - support Wireguard (ideally within containers)
    - ship with a default container runtime

    ultimately this would greatly simplify the scenario and and essentially turn linux containers into a first class citizen.

    Thanks, Joachim

  2. Please make long doubles work in WSL

    Long doubles are not working. For example, the pow function gives wrong results. This bug has been known for 3 years. Please fix it. The loader could set the FP control word differently depending on the type of executable. See https://github.com/Microsoft/WSL/issues/830

  3. 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

  4. Support for sparse files in LxFS (flow type checker fails) WSL#1732

    This issue says it better than I can:

    https://github.com/Microsoft/WSL/issues/1732

    Real Linux:

    $ truncate -s 27927781376 foo
    $ ls -l foo
    -rw-r--r-- 1 ken ken 27927781376 Feb 27 21:00 foo
    $ du --block-size=1 foo
    0 foo

    WSL 15042:

    $ truncate -s 27927781376 foo
    $ ls -l foo
    -rw-r--r-- 1 ken ken 27927781376 Feb 27 21:00 foo
    $ du --block-size=1 foo
    27927781376 foo

  5. WSL: Add Hardwaresupport for Video capture devices

    Hello,
    I want to use process my webcam stream via OpenCV. Apparently there is no support for webcams yet, as /dev/ is pretty empty.

    ´--- Opening /dev/video0...

  6. 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?

  7. Integrate with Crossmeta that provides BSD VFS

    Allow integration of Crossmeta BSD VFS driver with WSL and many of the problems voiced here can be solved. The Crossmeta system provides all the VFS related POSIX syscalls with BusyBox already within WIN subsystem itself.

    Related Links:
    BSD VFS information:
    https://github.com/crossmeta/sys

    FUSE for Windows. This is real FUSE port that supports Low-Level and High-Level interface of Linux fuse.
    https://github.com/crossmeta/cxfuse

    It already supports mounting XFS, EXT2/3/4, HFS+

    Supports loop back devices of files or VHD images(losetup)

    Raw disk access with PnP support for USB or Cloud Disks

  8. Any plans for WSL on windows 10 phone?

    As a developer, being able to do tiny things, or SSH to a server, with a device always within arms reach would be really useful. I think this would renew interest Windows phone devices.

  10. lrzsz support in wsl console

    Most linux distributions offer the `lrzsz` package for uploading/downloading arbitrary files using the z-modem protocol. I use SecureCRT from VanDyke that allows:
    1. running a linux command such as `sz /etc/hosts` that drops the requested file(s) into a configurable local folder (e.g the windows desktop).
    2. drag'n'drop one or more files onto the terminal window invokes the `rz` linux command which receives the dropped files into the current linux folder (non-destructively) with their correct filenames.
    This highly useful functionality can be used within nested SSH sessions to pull/push arbitrary files between local windows folders and remote linux machines.

  11. 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

  12. WSL multiple users

    I installed WSL on our 2016 Server. But other users get the message" Windows Subsystem for Linux has no installed distributions.
    Distributions can be installed by visiting the Microsoft Store:
    https://aka.ms/wslstore"
    How do I make BASH available to other users on the server?

  13. New "Linux" kernel in June?

    Ok, I've got a question... how is the <quote>new linux kernel<endquote> going to affect this stuff? Because what I care about is full USB support, OpenCL and CUDA. If it's not going to fix those I'll drop this stuff and just install a real linux.

  14. need ability to use uinput for simulated HID events

    need the ability to run modprobe uinput but that fails with

    cicorias@cicorias-x1:~$ modprobe uinput
    modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.4.0-17763-Microsoft/modules.dep.bin'
    modprobe: FATAL: Module uinput not found in directory /lib/modules/4.4.0-17763-Microsoft
    cicorias@cicorias-x1:~$
    winver: 1809 17763.437

    What should happen is

    modprobe uinput # runs and returns 0

    # from the /dev path
    ls -al |grep input
    drwxr-xr-x 3 root root 160 Apr 25 04:47 input
    crw------- 1 root root 10, 223 Apr 25 04:47 uinput
    # should see uinput listed

  16. 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'})))
    }

  17. 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…

  18. Add framebuffer support (/dev/fb0)

    First of all, WSL is great! Thanks for this amazing feature!

    Now, please support frame-buffer device implementation, we develop many C/C++ apps that draws its graphs directly by open fb like this:

    int open_framebuffer(void)
    {
    const char *fbname;
    int ret;

    fbname = getenv("FB");
    if (fbname == 0)
    fbname = "/dev/fb0";

    ret = open(fbname, O_RDWR);
    if (ret == -1)
    ret = open("/dev/fb/0", O_RDWR);

    return ret;
    }

    WSL has no framebuffer device yet, so please bring us a complete fb0 device!

  20. 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.
