How I can simulate “tail” command for file on the Android file system?

Question

I have file on SD-CARD and my app using it as log file. Is it possible through the adb to watch file with all changes in real time? Like with tail -f /sdcard/myfile.log

Answer 1

You can install busybox and then:

adb shell
tail -f /path/of/your/file

But remember that you should have root access to install busybox. If you are using the emulator check this one: How to get root access on Android emulator?
