4、initrd.img是Linux启动过程中很重要的一个文件,如果你编译内核时将一部分功能编译为可加载模块。如果系统的一些设备的驱动编译为可加载模块,那么启动时如果没有指定INITRD=/path_to_initrd.img,那么系统启动或者会失败,或者启动后会有设备无法使用(像网卡或者其 它设备)。 如果没指定initrd.img或者指定的initrd.im...

Console.WriteLine里面用这个函数,主要是确保Linux下Dup设置的流指向以及Windows下WriteFile设置的流指向是正确的,不会错乱。 二:Linux dup+dup2 1.dup 在上一篇讲了下Console.WriteLine在Linux下调用了dup设置了流指向为终端输出,通过这个流指向把WriteLine参数里面的字符串给它打印到屏幕上。本篇补充一些细节。
In the Linux operating system, text editors are of two kinds that is the graphical user interface (GUI) and command-line text editors (console or terminal).
