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. 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?

  2. 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.

  3. Support AF_PACKET address family (tcpdump/wireshark...)

    From https://github.com/Microsoft/BashOnWindows/issues/1628

    It would be great to get support for AF_PACKET, as some networking tools or software rely on that.

    Samples of tool that won't work without it:
    - tcpdump (socket: Invalid argument)
    - wireshark
    - some nmap functions
    - Scapy

    This ask is on our backlog. When we make progress, we’ll update the status of this issue.

    If you’ve not seen this ask’s status change it’s because we’ve not yet started work on this ask. Like many longer-standing asks, this is a very complex issue and requires significant engineering effort which has to be prioritized and funded.

    Polite Ask: PLEASE DON’T POST +1 COMMENTSTHIS IS USERVOICEUPVOTE THE ASK ITSELF.

    POSTING +1’s SIMPLY ADDS NOISE & DEVALUES OTHERS’ VALUABLE FEEDBACK.

  4. Windows Console should support tabbed 'pages'

    Great to see some of these improvements, especially the cut/copy/paste keyboard shortcuts. However, I've been seeking for a way for the cmd window to have a tabbed interface for a while. So, for example, I can run a ping/tracert etc. in one tab, a chkdsk in another tab, and something else in a third, without having multiple windows open taking up screen real estate.

    Also consider adding panes side-by-side within the console.

  5. 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.

  6. 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:

    USB Serial communicatons:

  7. Support mounting xfs/ext2/ext3/ext4/etc. partitions / drives / loop files

    I have a multi-boot laptop, and would like to mount my xfs / extn / etc. partitions and boot to linux only when needed.

  8. 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!

  9. UTF-8

    I really really want utf-8, I do not use any legacy console apps from 80-s, so please please please make it happens :)

    As Chip said, UTF-16 is rather baked into the stuff we do. The console host does use UTF-16 somewhere in there. :P We just have the matter of dealing with code pages throughout the history of computing existence that causes us heartburn every time we think about how to fix this. :( It’s definitely something that we would like to look into on our backlog.

  10. Add libusb support to WSL

    Since previous one(https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/16759696-add-usb-device-support) was marked "complete", this one more clearly states support for libusb as in any usb device raw, rather than just storage mounting and serial pass-through.
    My example need is Yubikey gpg-card.

  11. 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…

  12. Make WSL filesystem accessible from Windows

    Access to the Windows filesystem from WSL is easy enough. Now we need access to the WSL filesystem from Windows.

  13. 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.

  14. Access to "real" linux devices in /dev

    ...or at least to /dev/sda? (disks) block devices. It could be very powerful to run things like
    dd if=/dev/sda2 of=some-remote-mounted-volume/my-backup-C.img

    Related to “Add USB Device support”: https://wpdev.uservoice.com/forums/266908-command-prompt-console-bash-on-ubuntu-on-windo/suggestions/16759696-add-usb-device-support

    This is a common ask and, now that we’ve gotten through most of the fundamental engineering, we’ll be more able to start looking-into device support sometime relatively soon, though no guarantees about when and what ;)

  15. Support iptables

    Originally posted on Github around a year ago: https://github.com/Microsoft/WSL/issues/767

    Not sure how feasible this is to implement, but I've found myself in a couple of situations where it would've come in quite useful.

    I want to point out that we have very clear that WSL does not support X/GUI desktops, apps, and tools.

    This said, we totally understand the utility of audio support in several scenarios. While this is not currently a high priority for us, it’s something we’ll definitely consider for the future.

    If you’re interested in accessibility & screen reader support, we’ve actually exposed the contents of the Windows Console to UIA for the first time in Fall Creators Update, allowing Narrator & other screen readers to read command-line output more easily: https://blogs.msdn.microsoft.com/commandline/2017/10/11/whats-new-in-windows-console-in-windows-10-fall-creators-update/

  17. Make links clickable

    Parse console output for urls and make it possible to open them with a click (or ctrl+click).

    Yep, this would be really cool. Not just for URLs, but things like paths too. Script emits a path to an error log? Just ctrl+click it to open!

    I can see some trickery around the parsing (performance impacts? security? and of course the parsing itself…) and the launching of another app (security again?). But it would be awesome.

    It’s on our backlog for sure.

  18. Mouse Scroll Wheel or CTRL +/- to zoom text size

  19. Run services when Windows starts?

    In Bash, I can set services to boot on startup with something like this:

    sudo systemctl enable application.service

    However, it would be really handy if certain Bash services started when Windows started. (especially for web servers, database engines etc.)

    I know the way Windows and Linux does services is quite different but as an example, it would be great if I could start Windows and know that my local MongoDB server is all fired up and ready to go.

    Would love to know other peoples thoughts on this and if it's at all feasible?

    Thanks, Anthony
