到目前为止，我已经尝试使用以下方法sed：
sed -n '/^$/!{s/<[^>]*>//g;p;}' file.html
我得到以下输出：

答案1
输出sed完全awk取决于 HTML 文件的格式。例如，修订 #3会产生不同的结果修订 #4。
或者，您可以使用特定工具，例如html2text.html2text会将生成的 HTML 页面格式化为纯文本字符。当然，您可以使用其他命令行工具（例如sed和）进一步处理输出awk。
要安装html2text，只需运行：
sudo apt install html2text
要开始，只需运行：
html2text file.html
默认情况下，html2text将 HTML 文档格式化为屏幕宽度为 79 个字符。因此，结果将如下所示：

但是，您可以将宽度更改为所需的字符数。例如，在您的问题中，宽度为 261 个字符。因此，您也可以使用
html2text -width 261 file.html
其结果为：

现在，要进行操作，例如删除字形 ( |)、下划线 ( _)、空行、第一行和最后 3 行，您可以根据需要使用任何命令行工具。一种丑陋的方法看起来像
html2text -width 200 file.html | sed 's/|/\ /g;s/\_/\ /g;/^$/d'| head -n -3 | tail -n +2
这将产生

我更喜欢在带有指令的文件命令中使用带有“sed句子”的“vim”，然后使用“vim -s 文件命令”执行。
