I modified utils.py so that psutil does not raise a NameError in the case when psutil is not present. The original code of get_parent_process_name() would always raise an Exception in the past just from checking if psutil: if psutil was not successfully imported, and thus would always return the empty string "" without being able to fall back on executing the ps subprocess.
In addition, I used args= instead of cmd= in the ps command, because it is a synonym and is more universal. args= works on macOS (and presumably BSD) but cmd= does not.
I also removed a preceding - from the process name, in case the shell was called as a login shell.
