    噗，我感觉有点跑偏了，肯定有很多种方式实现这个功能，我只是觉得用 web 这种方式可能更方便一下，把文本复制一下就行，不需要再敲什么命令了。

    不给出无用前缀的具体定义，不敢用
    PS: 一条 sed 命令的事，也犯不着用

    @wweir 呃，要删的字符是你自己指定的呀，主要我也没用过 sed，而且这个逻辑也比较简单，所以就自己写了个。

    @Rico 我之前也用 vim 弄过，感觉还是有点限制，比如下面的这种
    ```
    aaaaaa
    + aaaaaaaaaa
    ggggggggg
    + gggggggg
    ggggggggg
    + gggggggg
    ggggggggg
    + gggggggg
    ggggggggg
    + gggggggg
    ```

    Delete Line Numbers

    怕不是平时在国内的辣鸡带 Line Number 的网站复制代码太多了，才会想出这样的一个解决方案。

    也就只有国内的那些网站复制代码会带 Line Number 的

    @Kilerd 噗，写这个的主要目的是在复制代码片段到博客上的时候，去掉前面多余的空格。
