前提
AWK是一種處理文本文件的語言，是一個(gè)強(qiáng)大的文本分析工具。
本文將使用命令awk將具有某個(gè)關(guān)鍵字的段落提取出來。

段落提取
假設(shè)我們需要的關(guān)鍵字為 nid=0x63ef
keywords=0x63ef
## 以前后雙換行符為一個(gè)段落
## 查詢包含關(guān)鍵字nid=0x63ef的段落
awk 'BEGIN {RS = "\n\n+";ORS = "\n\n"} /'$awk,關(guān)鍵字段落,awk,提取關(guān)鍵字'/ {print $0}' test.log
## 查詢不包含關(guān)鍵字nid=0x63ef的段落
awk 'BEGIN {RS = "\n\n+";ORS = "\n\n"} !/'$awk,關(guān)鍵字段落,awk,提取關(guān)鍵字'/ {print $0}' test.log
