For example, under a Linux operating system, the ampersand character (&) following the command causes the program to be
spawned as a new background process. This technique is useful in script programs, as it allows the script to proceed after a new
process is started for the VMCLI command (otherwise, the script blocks until the VMCLI program is terminated).
When multiple VMCLI sessions are started, use the operating system-specific facilities for listing and terminating processes.
