Vv

-vv

Flag / Symbol · /viː viː/ · the double-verbose flag used in Unix command-line tools to enable maximum debug output

Definition

-vv is the double-verbose flag — a command-line option that instructs a tool to output the maximum level of diagnostic information. While -v gives you basic status messages, -vv opens the full debug stream: request headers, response bodies, timing data, internal state, and every decision the programme makes as it runs. It is your deepest diagnostic lens.

Usage

Used with curl, ssh, ansible, git, openssl, ffmpeg, and most Unix CLI tools. Type curl -vv https://example.com and the terminal floods with every handshake step, every header, every byte count. In ansible, -vv shows the task variables and module arguments. The pattern scales: some tools go -vvv or -vvvv for even deeper output.
