If the file is not write-protected, Virtual Media may write to the image file. To make sure that Virtual Media does not write to the media:

Configure the operating system to write-protect a floppy image file that must not be overwritten.

Use the write-protection feature of the device.

When virtualizing read-only image files, multiple sessions can use the same image media simultaneously.

When virtualizing physical drives, only one session can access a given physical drive at a time.

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.
