https://www.cnblogs.com/linux-37ge/articles/10212377.html 介绍 什么是input输入子系统? Linux系统支持的输入设备繁多,例如键盘、鼠标、触摸屏、手柄或者是一些输入设备像体感输入等等,Linux系统是如何管理如此之多的不同类型、不同原理、不同的输入信息的输入设备的呢?其实就是通过input输入子系统这套软件体系来完...

解决方法:可以使用evdev库在Linux中处理设备输入。 代码语言:txt 复制 from evdev import InputDevice, categorize, ecodes # 查找鼠标设备 devices = [InputDevice(path) for path in evdev.list_devices()] mouse = None for device in devices: if 'mouse' in device.name.lower(): mouse = device break...

The important things when dealing with arguments in your shell scripts are to have a clear understanding of: What form might the content of an argument take? If it is provided as a variable, what did the "sender" put in that variable for you?
-n 作用就是 抑制换行 这里 就是输出 "Input another number: " 后不换行。echo
透过图 9.3-4 你就可以更轻松的了解到,事实上与本机最有关的其实是 filter 这个表格内的 INPUT 与 OUTPUT 这两条链,如果你的 iptables 只是用来保护 Linux 主机本身的话,那 nat 的规则根本就不需要理他,直接设定为开放即可。 不过,如果你的防火墙事实上是用来管制 LAN 内的其他主机的话,那么你就必须要再针...
lo 本机内部的循环端口 这句就是说不是本机交流的信息都记日志 感叹号
