VMCLI operating system shell options

VMCLI uses shell options to enable the following operating system features:

• stderr/stdout redirection — Redirects any printed utility output to a file.

  For example, using the greater-than character (>) followed by a filename overwrites the specified file with the printed output of the VMCLI utility.

  NOTE The VMCLI utility does not read from standard input (stdin). Hence, stdin redirection is not required.
• Background execution — By default, the VMCLI utility runs in the foreground. Use the operating system's command shell features for the utility to run in the background.

  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.
