android – Ubuntu命令行中adb logcat的颜色

要从Android设备获取logcat,我使用adb shell logcat(在混合中也使用了一些grep过滤).

示例输出如下：

E/com.samsung.app( 3739): [MSC]>>>...
I/InputDispatcher( 2882): Delivering ...
D/ProgramMonitor( 3770): START ...
D/ProgramMonitor( 3770): LAUNCHER_RESUME...
I/Debug   ( 3815): onReceive...
E/Debug   ( 3815): receive ...
D/ClientReporter( 3036): ...

我的问题是,如何根据日志的首字母更改输出的颜色.所以“E”用红色打印,“D”用绿色打印等等……就像在Eclipse中看日志的方式类似.

谢谢

解决方法:

我使用我在这里找到的python脚本：

Modifying the Android logcat stream for full-color debugging

如果你愿意,它真的很容易使用和修改.
