The cmsh command provides the command-line interface for the Base Command Manager. To execute cmsh commands non-interactively from a system shell (like bash), the -c flag is used. This flag takes a single string argument containing the command(s) to be executed. When multiple commands need to be run, they must be separated by a semicolon (;) within the quoted string. The command cmsh -c “main showprofile; device status apc01” correctly invokes the shell, executes the two specified commands in sequence, and then exits.

B. The -p flag is not a valid option for executing a command string within cmsh.

C. system is a mode within the cmsh interactive shell, not a command to invoke the shell from the system command line.

D. cmsh-system is not a valid command or executable in the Base Command Manager environment.

1. NVIDIA Bright Cluster Manager 9.2, Administrator Manual, Chapter 5: The Cluster Management Shell (CMSH), Section 5.1.1: CMSH Command-line Options. The documentation specifies the use of the -c option to "Execute the specified command and then exit. Multiple commands can be separated by a semicolon." This directly validates the syntax used in option A.
