LINUX中,find結合grep正則表達式,快速查找代碼文件。

###目的###
LINUX中,find結合grep正則表達式快速查找代碼。

例如常常有需求：
查找當前目錄下全部.h文件中，"public開頭,中間任意字符,以VideoFrameReceiver結束" 的文件名。
find . -iname "*.h" -type f | xargs grep --color -n ".*public.*VideoFrameReceiver.*"

例如輸出：
./components/mirroring/browser/single_client_video_capture_host.h:36: public media::VideoFrameReceiver {
./media/capture/video/mock_video_frame_receiver.h:13:class MockVideoFrameReceiver : public VideoFrameReceiver {
./media/capture/video/video_frame_receiver_on_task_runner.h:19: : public VideoFrameReceiver {
./services/video_capture/receiver_mojo_to_media_adapter.h:16:class ReceiverMojoToMediaAdapter : public media::VideoFrameReceiver {
./content/browser/renderer_host/media/video_capture_controller.h:40: : public media::VideoFrameReceiver,
