如何使用 ADB 作为后台进程运行命令？

Question

I am trying to run logcat in background using adb.

adb shell "logcat -r 2000 -f /data/local/test.log &"

But it does not work. If I do adb shell ps | grep logcat adb shell ps | grep logcat I dont see logcat process running.

Answer 1

添加 nohup 似乎有效。
adb shell "nohup logcat -r 2000 -f /data/local/test.log &"

Answer 2

If you can't run nohup directly, then you could try this: busybox nohup logcat

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. So it has nohup feature as well and you could use it via busybox if manufacturer turns nohup option on at compile time.
