You are performing an audit of a new piece of software you have installed to your system. The systemd service unit for the new piece of software is whackyd.service. Analyze the process started by this systemd service unit (which is already running), and perform the following tasks:

Task

1. Write a list of files opened for read or write to the file /opt/answers/read_write.txt, one per line. The output file has been created for your convenience. Be sure to include the absolute path to each file.

2. The whackyd daemon process is listening on a TCP port. Write the port number (and only the port number) that the whackyd daemon is listening on to the file /opt/answers/tcp_port.txt. The output file has been created for your convenience.

3. After reading the documentation for the software, you note that in order to have the whackyd daemon perform its garbage collection routine, it must be sent a SIGHUP signal. Send the whackyd process a SIGHUP signal.
