从文本文件中解析出必要的部分答案

【问题标题】：Parse out of a textfile necessary parts从文本文件中解析出必要的部分

【问题描述】：

我从地址清理程序中得到了这个输出：

我需要带有关键字SUMMARY 的行。我需要解析的内容是：

 AddressSanitizer 

 heap-buffer-overflow 

 main.cpp

 5

是否可以使用 bash 工具或类似的工具来做到这一点？

我问，因为它总是具有相同的输出结构，并且只需要带有这些关键字的这一行

【解决方案1】：

你可以使用这个 awk 命令：

awk -F '[ :]+' -v OFS='\n\n' '/SUMMARY/{sub(/.*\//, "", $4); print $2, $3, $4, $5}' file
AddressSanitizer

heap-buffer-overflow

main.cpp

5
