Windows 10预览版14316开启Linux Bash命令行

Windows 10预览版14316中已经提供bash组件,默认关闭的,启用的方法是先选中“开始->设置->更新和安全->针对开发人员->开发人员模式”,然后按 Win+X,F 打开“程序和功能”,点击左侧的“启用或关闭Windows功能”,然后找到并勾选 Windows Subsystem for Linux (Beta) ,确定后会提示重启启动系统。

Windows 10预览版14316开启Linux Bash命令行

系统重启完成后,按 Win+X,A 打开命令提示符(或者按 Win+R 打开运行对话框),输入 bash 回车,第一次运行会从网上下载Ubuntu linux组件,按提示输入y。

查看版本信息和分区映射:

root@localhost:~# uname -a

root@localhost:~# sudo ls /dev
adss   fb0    kmsg  ptmx  random  tty   urandom

root@localhost:~#

注意是root用户,/dev 下也没有很多的设备,输入 exit 可退出bash。

 /root 目录对应Windows系统的 %localappdata%\lxss\root 文件夹(注意,不要删除lxss目录,bash会失败)。

如果不幸删除了lxss或者其他原因 bash 启动失败。可以在CMD里用下面两条命令卸载再重新安装:

echo y|lxrun /uninstall
echo y|lxrun /install

更新linux子系统,在CMD里运行:

lxrun /update                    // 更新linux子系统
// - 或者 -
lxrun /update /critical          // 只更新关键更新,更新完成后会强制关闭linux进程

使用命令 apt-get 安装软件前建议先在 /etc/apt/sources.list 文件前端添加国内的镜像服务器, http://mirrors.163.com/ubuntu 是163的镜像源:

deb http://mirrors.163.com/ubuntu trusty main restricted universe multiverse
deb http://mirrors.163.com/ubuntu trusty-upadates main restricted universe multi
verse
deb http://mirrors.163.com/ubuntu trusty-security main restricted universe multiverse

可用vi编辑:

vi /etc/apt/sources.list

按3yy复制原来的3行,按Shift+G到结尾,按p粘贴。输入 :1,3s/\w*\.ubuntu/mirrors.163/ 替换前3行为163的镜像,Shift+ZZ保存退出。

然后用 apt-get update 命令更新源(163的更新源最后会出现一些校验警告,可以忽略)。

安装 git: 

apt-get --assume-yes install git

--assume-yes可选:安装交互全部yes。

删除用remove替换install。

自动移除:

apt-get autoremove

查询7z软件:

apt-cache search 7z

下面是安装swift编译环境的例子(未成功):

1. 安装 CLang 和 libicu-dev

apt-get install clang libicu-dev

2. 下载swift发行包(到swift.org里找ubuntu14.04平台的版本,目前DEV快照是Swift 3.0预览版本)

curl -O https://swift.org/builds/development/ubuntu1404/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz

注:可以先在Windows系统中用下载工具下载好,然后用touch命令在linux文件系统里先创建个同名的文件

root@localhost:~# touch swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz

然后再用Windows进行文件复制,覆盖到 %localappdata%\lxss\root 文件夹里。

3. 解压tar.gz包。

tar xzf swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz

如果产生了如下错误:

root@localhost:~# tar zxf swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.ta
r.gz

tar: Exiting with failure status due to previous errors

改用7z来解压,设置可执行权限。

rm -rf swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04
apt-get install p7zip-full
7z x swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar.gz
7z x swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar
rm swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04.tar
chmod +x /root/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin/*

 4. 配置环境变量,编辑 ~/.bashrc 文件,结尾加入

export PATH=/root/swift-DEVELOPMENT-SNAPSHOT-2016-03-24-a-ubuntu14.04/usr/bin:"${PATH}"

5. 重新载入配置,查看结果:

root@localhost:~# source ~/.bashrc
root@localhost:~# swift --version
Swift version 3.0-dev (LLVM b010debd0e, Clang 3e4d01d89b, Swift 7182c58cb2)
Target: x86_64-unknown-linux-gnu
root@localhost:~#

6. 目前仍不能进入REPL环境或者编译swift文件。
