grep/egrep 中是否有办法从该文本中提取棘手的模式，将它们插入行的开头及其剩余行，使其看起来如下所示？

从许多包含“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，使名称从行首开始，以便于阅读。在它们之间插入一个空行也会有所帮助，但这在 egrep 中可能是不可能的？

输入：

看评论; 输入实际上是：

BedsDivans/Type4567345.xml:Nonspecific bed abnormalities

您可以将输出加倍以匹配预期输出：

sed G input.txt > output.txt

顺便说一句，如果您想让事情更容易阅读，您可以尝试 G 的数量。例如，这将使您的文件空间增加三倍：

sed G;G input.txt > output.txt

此外，要直接对您的文件进行更改，您可以使用该-i标志（这使我们不必不必要地创建output.txt）：

sed -i G input.txt
