In the process we will expect to see linux with ps -ef | grep XXX
But seeing is not a full path, how to see the full path to it?
After each process starts in / proc following a path corresponding to the pid
For example: ps -ef | grep python
Display: oracle 4431 4366 0 18:56 pts / 2 00:00:00 python Server.py
4431 is the process ID
To the next / proc / 4431, ls -l will see:

Note cwd, a process that is the path you want to find. .
