由于一些工作环境无法上网,而且需要经常使用linux命令,但是如果对linux命令不熟悉,效率就会很低。

正好最近在学习tkinter,就自己写一个linux帮助手册,既熟悉命令,又练习python,下面是源代码:

Python Tkinter实现的linux命令帮助手册


鼠标或键盘箭头移动到所要查看的命令,回车即可在右恻查看命 令帮助文档。

搜索框内可直接输入要查询的命令,回车或点击搜索图标均可。

如果要添加新的命令文档,可以向指定目录里放入txt格式文件即可。


左边是一个frame,由一个scrollbar和listbox组成, 右上边的搜索框也是一个由entry和button组成的frame,下面是text控件,用来显示相应listbox上的文件信息。


不足之处请指出,谢谢!
