How to run command as background process using ADB?

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 I dont see logcat process running.

Adding nohup seems to work.
adb shell "nohup logcat -r 2000 -f /data/local/test.log &"
