Android log抓取工具

工作需要抓取Android Log，Linux下使用命令行比较麻烦，弄了一个工具比较方便的抓取和存储Log

编译命令：gcc log.c -lpthread -o logfilter
与指纹相关的Log有3种，Android CA Log、TEE Log、kernel Log。命令参数对应如下：
1、-c：Android logcat输出的Log，包含Android上层的所有Log
2、-t：TEE下的所有的Log
3、-k：kernel的Log
4、-i：显示的Log不需要筛选关键词
5、-a：存储的Log不需要筛选关键词
6、-clean：删除Log存储目录下的所有Log文件
7、-help：输出帮助信息
另外在Log存储目录下有log_tag.txt文件用来存储所有曾使用过的筛选关键词
使用命令：logfilter -ca ‘fingerprintservice|FingerprintManager’ 打印只包含"fingerprintservice|FingerprintManager"的Log但是存储的是全部的CA Log
PS：有动态抓取log的工具logfilter，Linux下可以完美运行，不过将系统语言设置为英文UI界面会好看一些
