Question

grep / egrep中是否有一种方法可以从这个文本中提取棘手的模式，将它们插入到行的开头，并使用其行余数，以便它看起来如下所示？

从许多具有“非特定”一词的文件中提取的原始文本。现在我需要组织这些，以便名称从行的开头开始，以便更容易阅读。这也有助于在它们之间插入一个空白行，但这在egrep中是不可能的？

输入：

您可以将输出空间加倍以匹配预期输出：

sed G input.txt > output.txt

另外，如果你想让事情更容易阅读，你可以试验G的数量。例如，这会使文件空间增加三倍：

sed G;G input.txt > output.txt

此外，要直接对您的文件进行更改，您可以使用-i标记（这可以避免我们不必要地创建output.txt）：

sed -i G input.txt

在egrep中提取模式并将它们放在输出文件中的行首？
