How to specify threads open for every application on Linux?

Question

Is there a way to find out, in real time, which streams are open and which application has opened them?

Answer 1

You can see /proc/<PID>/task/(where <PID>is the process identifier), which will contain several subdirectories, each of which has a name equal to the thread identifier of one of the threads in this task.

Please note that this is only real-time sorting, but if you do not want to “freeze” the entire system for a while, the information you receive can always be outdated, since the process can create or destroy threads, even if you look at the data .
