search - Grep 查找字符串并读取内容直到下一个匹配字符串

Question

我正在尝试读取文件并使用 grep 搜索字符串。一旦找到该字符串，我想读取该字符串之后的所有内容，直到匹配另一个字符串。因此，在我的示例中，我正在搜索 ...SUMMARY... 并且我想读取所有内容，直到出现 ... 这是一个示例:

**...SUMMARY...**
   Severe thunderstorms are most likely across north-central/northeast
   Texas and the Ark-La-Tex region during the late afternoon and
   evening. Destructive hail and wind, along with a few tornadoes are
   possible. Severe thunderstorms are also expected across the
   Mid-South and Ohio Valley.

   **...**North-central/northeast TX and southeast OK/ArkLaTex...
   In the wake of a decaying MCS across the Lower Mississippi River
   Valley, a northwestward-extending outflow boundary will continue to
   modify/drift northward with rapid/strong destabilization this
   afternoon particularly along and south of it. A quick
   reestablishment of lower/some middle 70s F surface dewpoints will
   occur into prior-MCS-impacted areas, with MLCAPE in excess of 4000
   J/kg expected for parts of north-central/northeast Texas into far
   southeast Oklahoma and the nearby ArkLaTex. Special 19Z observed
   soundings are expected from Fort Worth/Shreveport to help better
   gauge/confirm this destabilization trend and the degree of capping.

我尝试使用以下代码，但仅显示 ...SUMMARY... 和下一行。

sed -n '/...SUMMARY.../,/.../p' 

我该如何解决这个问题？

================================================== =======================后续:

这就是我想要得到的结果。只显示...摘要...下的段落，并在下一个结束...所以这就是我最终应该得到的:

中北部/东北部地区最有可能出现强雷暴 德克萨斯州和阿克-拉-德克萨斯地区下午晚些时候和 晚上。破坏性的冰雹和大风，以及一些 Tornado 可能的。预计全境还将出现强雷暴天气 中南部和俄亥俄河谷。

我根据 Shellter 的建议尝试了以下操作:

sed -n '/...摘要.../,/**...**/p'

但我得到了一切。

Answer 1

您可以使用

sed -n '/^[[:blank:]]*\.\.\.SUMMARY\.\.\./,/^[[:blank:]]*\.\.\./{//!p;}' file

参见this online sed demo .

注释:

• 转义文字点
• 文字星号也应该被转义，并且它们是必需的，因为 /.../ 仅匹配具有任意 3 个字符的行
• ^ 匹配行的开头，[[:space:]]* 匹配任何 0+ 空白字符
• {//!p;} 获取两行之间的内容(不包括这些行)(请参阅 How to print lines between two patterns, inclusive or exclusive (in sed, AWK or Perl)? )
