How do you enable verbose mode for command output?

• A. Using the '-v' option
• B. Using the '--verbose' option
• C. Using the '-q' option
• D. Using the 'trace' command

Answer: (A)

Enabling verbose mode for command output typically involves providing specific options that instruct the command to give more detailed information about its operations. The use of the '-v' option is a common convention in many command-line tools and scripts across various UNIX-like systems, including Linux. This option prompts the command to provide more informative messages about what it is doing, which can be helpful for debugging or understanding its process. While the '--verbose' option is also a valid way to enable verbose output in some commands, it is typically longer and used in commands that support both short and long forms of options. The '-q' option generally signifies 'quiet mode', which suppresses output rather than increasing it, and the 'trace' command may not directly relate to enabling verbose output, depending on the context. Therefore, the '-v' option is a standard and concise way to request verbose output in command-line interfaces.
