原字符串
printf("ERROR: file:%s line:%u\n", __FILE__, __LINE__);
改后字符串
printf("ERROR in file:%s +%u\n", __FILE__, __LINE__);
注意这里有待转译的符合.
#验证
echo `grep -inrl "printf(\"ERROR: file:%s line:%u\\\\\\\n\", __FILE__, __LINE__);"`
sed -i 's/printf("ERROR: file:%s line:%u\\n", __FILE__, __LINE__);/printf("ERROR in file:%s +%u\\n", __FILE__, __LINE__);/g' echo `grep -inrl "printf(\"ERROR: file:%s line:%u\\\\\\\n\", __FILE__, __LINE__);"`
