How do I output which files a process is calling upon?

Question

In terminal how do I output which files a process is calling upon? For instance, if I was using Adobe Premiere and I wanted show which project file Premiere had open via terminal.

Answer 1

Not sure what you mean by calling upon. If you are looking for all the files currently opened by your process, use lsof:

lsof -p PID

where PID is the ID of the process you are looking at.
