“With clarity and definition is associated *"id"='o123-3923-d2i71-0129p' ,a certain physical spareness. Most of the "id"='s0987-3923-d2i71-0129p' great deciduous trees of England give one the impression, at any rate in summer, of being rather o "id"='p4523-3923-d2i71-0129p' ,bese. In Scandinavian mythology Embla, the elm, was the first woman. Those who have lived "id"='o123-3923-d2i71-0129p' ,much with old elm trees—and I spent a good part of my boyhood under their ponderous shade—will "id"='m0962-3923-d2i71-0129p' ,agree that the Scandinavians were men of insight.

在这里，我只想获取 id。输出：

"id"='o123-3923-d2i71-0129p' "id"='s0987-3923-d2i71-0129p' "id"='p4523-3923-d2i71-0129p' "id"='o123-3923-d2i71-0129p'"id"='m0962-3923-d2i71-0129p'"id"='o123-3923-d2i71-0129p'

【问题讨论】：

不：（那段与我的要求无关，那些是机密的，这就是为什么我改变了整个。我只想知道那个特定语句的 linux 命令。
我认为您正在寻找grep，但是由于您标记了此Linux，我不知道您是否需要命令行实用程序或系统调用。

grep -oP '"id"='\''\w{4,5}-\w{4}-\w{5}-\w{5}'\'

顺便说一句：Lorem ipsum 是生成随机文本数据的好方法，每个人都很容易理解。有许多在线生成器可用。
