提取两个模式(不包括模式)之间的文本 [英] Extract text between two patterns excluding patterns

问题描述

考虑java -jar plantuml.jar -language的输出:

;type
;26
abstract
actor

............................

;color
;147
AliceBlue
AntiqueWhite
Aqua
Aquamarine
............................
Wheat
White
WhiteSmoke
Yellow
YellowGreen

;EOF

我需要从此文本中提取颜色，而不能包含字符串.我已经阅读了几篇文章和《问答》，但没有找到答案.在这里，我找到了最合适的答案.

I need to extract colors from this text without surrounding strings. I have read several articles and Q&As and did not found answer. Here i found the most suitable answer.

$ java -jar plantuml.jar -language | sed -n '/\;color/,/\n\n/{/color/!{/\n\n/!p}}'
;147
AliceBlue
AntiqueWhite
Aqua
Aquamarine
Azure
Beige
Bisque
....................
Teal
Thistle
Tomato
Turquoise
Violet
Wheat
White
WhiteSmoke
Yellow
YellowGreen

;EOF

有一个细微的差别:;147可以是任何其他值，而EOF可以随时更改为其他值.我尝试了sed -n '/\;color\s*\;\d*/,/\n\n/，但是它什么也没有返回.请帮助我获得下一个结果:

There is a small nuance: ;147 could be any other value and EOF could be changed at any time to something other. I tried sed -n '/\;color\s*\;\d*/,/\n\n/, but it returns nothing. Please help me to achieve the next result:

AliceBlue
AntiqueWhite
Aqua
Aquamarine
Azure
Beige
Bisque
....................
Teal
Thistle
Tomato
Turquoise
Violet
Wheat
White
WhiteSmoke
Yellow
YellowGreen

推荐答案

它听起来像您需要的所有声音:

It SOUNDS like all you need is:

awk '/^;/{if (/[[:alpha:]]/) f=(/color/?1:0); next} f'
