Microsoft Launches “Huge Improvements” for Ubuntu Bash in New Windows 10 Build

[Batu69]

The Windows Subsystem for Linux gets plenty of updates

   Microsoft keeps improving Ubuntu Bash on Windows 10

 

Microsoft rolled out Windows 10 build 14361 to insiders part of the fast ring a few hours ago, and in addition to several important goodies for Windows users, there are also new improvements for those who’re interested in the Ubuntu bash on Windows.

In an announcement today, Microsoft reveals that build 14361 brings “huge” changes to Bash on Ubuntu on Windows, including support in WSL for Pseudo Terminals (PTY), which leads to adding support for Tmux.

Additionally, with this release, Redmond is making DrvFs case sensitive in Bash, so there’s finally a difference between files such as case.txt and CASE.TXT, which can both be stored on /mnt/c drives.

What’s very important to note is that case sensitivity only works in Bash on Windows, so if you attempt to use it anywhere else, NTFS will report the files correctly, but “unexpected behavior may occur,” as Microsoft itself explains.

Additionally, users can now delete and chmod read only files from DrvFs, allow connection to 0.0.0.0 and :: as localhost, and opt out of auto-generated hosts file.

There’s more to discover in this new build, but if you want to check out all changes, have a look in the box after the jump to see the full release notes.

How to enable Ubuntu Bash on Windows

If you’re a new user who hasn’t activated Bash in Windows 10, you just need to follow a few simple steps to do it, and it doesn’t take more than a few minutes.

First and foremost, you need to turn on the Developer Mode, so open the Settings app and go to Update & Security > For developers. Then, you need to enable the Windows Subsystem for Linux, so click the Start button, open the classic Control Panel, go to Programs, and then click the option that reads “Turn Windows features on or off.” Look for the Windows Subsystem for Linux (Beta) and enable it.

The final step is to open a command prompt window with administrator privileges and type bash to start the installation process and get everything ready.

• Fixed install issue where user accounts not always created
• Optimized command line arg structure allowing for extremely long argument list. (GH #153)
• Now able to delete and chmod read_only files from DrvFs
• Fixed some instances where the terminal hangs on disconnect (GH #43)

• Allow connection to 0.0.0.0 and :: as localhost (GH #388)
• Sendmsg/recvmsg now handle an IO vector length of >1 (partial GH #376)

• Automatically match Linux locale to the NT locale during install (GH #11)
• Added the /proc/sys/vm/swappiness file (GH #306)
• strace now exits correctly
• Allow pipes to be reopened through /proc/self/fd (GH #222)
• Hide directories under %LOCALAPPDATA%lxss from DrvFs (GH #270)
• Better handling of bash.exe ~. Commands like “bash ~ -c ls” now supported (GH #467)
• Sockets now notify epoll read available during shutdown (GH #271)
• lxrun /uninstall does a better job of deleting the files and folders
• Corrected ps -f (GH #246)
• Improved support for x11 apps such as xEmacs (GH #481)

Ubuntu  is crap, that's all it's good for is windows 10 .. Ubuntu 16.04 versions  gave  me nothing but problems  on my AMD  machine..  Tt don't even want to run , AMD has no drivers for it.  Installed Manjaro Linux  16.06 and put  Cinnamon desktop on it,  it has newer packages than Ubuntu does and all new kernels  are working  with AMD proprietary drivers  . And no more having to fool with adding 3rd party PPA  . Ubuntu is Linux for Noobs i out grew it  because it not stable on most AMD boxes  and having to hunt for ppas to get updated packages.
