mingw Minimalist GNU for Windows
想要在Windows使用wget，之前使用的是单独的安装包，现在又想使用bash的命令提示符来执行wget。因为一个导出wget下载链接的工具，用单引号包括的下载链接，在Windows下不能用，win要用双引号。懒得改，就找到了mingw这个工具。
mingw和cygwin有啥区别呢？以前装过cygwin玩耍。
官网解释：
MinGW provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs. (It does depend on a number of DLLs provided by Microsoft themselves, as components of the operating system; most notable among these is MSVCRT.DLL, the Microsoft C runtime library. Additionally, threaded applications must ship with a freely distributable thread support DLL, provided as part of MinGW itself).
MinGW compilers provide access to the functionality of the Microsoft C runtime and some language-specific runtimes. MinGW, being Minimalist, does not, and never will, attempt to provide a POSIX runtime environment for POSIX application deployment on MS-Windows. If you want POSIX application deployment on this platform, please consider Cygwin instead.
另外POSIX是
POSIX (Portable Operating System Interface) is a set of standard operating system interfaces based on the Unix operating system.
先安装mingw提供的安装工具，这样可以选择性安装utility。
安装器把可安装的东西分了两类：
- Mingw提供的是开发用的编译器之类的
- MSYS (minimal system)一个命令界面的系统，带一些unix工具，可以替代Windows下的cmd这样可以更好的使用开源的一些应用，是cygwin-1.3的一个分支。
不解的是msys-wget这个工具在all类别下才能找到，开始在msys上找了半天。勾选之后，在菜单installation-apply changes就可以安装了，很方便。
然后找到安装目录msys/bin/msys.bat，执行之，就可以得到一些命令界面了，默认是sh.exe，这个应该是bash吧。
输入wget，就能执行wget下载东西了。如果要切换目录cd /e/vedio 就能切换到e盘的vedio目录了。
