我正在使用grep寻找特定的块
例如,我从android设备获得以下输出:

- STREAM_VOICE_CALL:

我需要使用grep获取** **内的块,我需要哪个代码grep命令来找到该特定的输出块? 我已经尝试过
adb shell dumpsys音频| grep {STREAM_MUSIC:,STREAM_ALARM}和 没有返回任何adb shell dumpsys音频| grep -w STREAM_MUSIC 仅返回第一行
答案 0 :(得分:0)
如果可以使用awk
,则可以执行以下操作:
awk '/- STREAM/ {f=0} /- STREAM_MUSIC:/ {f=1} f'
- STREAM_MUSIC:
Muted: false
Min: 0
Max: 15
Current: 2 (speaker): 12, 4000000 (usb_headset): 3, 40000000 (default): 8
Devices: speaker
