sed 解析编译器警告消息

Question

我尝试使用 sed 获取文件路径、行号、编译器警告号和警告消息，但失败了。

> grep -E "C6001|C6011|C28197" release-log.txt | head | sed -r 's/^([a-zA-Z\\:.]+)\(([0-9]+)\) warning (C[0-9]+): (.+).(.+)$/(\3) \1:\2 \4/g'

例如，给定：

C:\WindowsFabric\src\prod\ktl\src\inc\kallocator.h(196): warning C6011: Dereferencing NULL pointer 'Allocator'. : Lines: 189, 196 [C:\WindowsFabric\src\prod\src\Lease\KTransport\user\KTransport.user.vcxproj]

我想要：

(C6011) C:\WindowsFabric\src\prod\ktl\src\inc\kallocator.h:196 Dereferencing NULL pointer 'Allocator'

Answer 1

假设所有行的结构都与示例行一样，这是可行的。

sed -r "s/^(C:[^(]+)[(](.+)[)]: warning ([^:]+):(.+').*/(\3) \1:\2 \4/" yourFile.txt
