17.7.5 List of Open Files: lsof
To view a list of all the files open for the process with process ID PID, use -p. For
example, to view all the files used by the current shell, enter:
tester@linux:~> lsof -p $$

The special shell variable $$, whose value is the process ID of the shell, has been used.
The command lsof lists all the files currently open when used without any parameters.
Because there are often thousands of open files, listing all of them is rarely useful.
However, the list of all files can be combined with search functions to generate useful
lists. For example, list all used character devices:
tester@linux:~> lsof | grep CHR
