how to check open file without lsof
android, lsof
Solution
Poor man's lsof is to execute
ls -l /proc/[process id]/fd
Still, you need to be root.
Problem
In linux, I use lsof to check the file is opened by which process. I have an android device, but no lsof command. Is it possible to find which process open the specific file ? I will use it to verify the MediaPlayer hold a fd, but it should be closed.
