詳細なフラグがどのように機能するかを理解しようとしていますが、失敗しました。マニュアルページと資格リファレンスガイド。
唯一のヘルプの使用法は次のとおりです。https://www.debian.org/doc/manuals/aptitude/ch02s05s05.en.html#configCmdLine-Verbose:
オプション：
Aptitude::CmdLine::Verbose
基本：0
説明する： コマンドラインモードの詳細度を制御します。資格はい。このコマンドラインオプションが表示されるたびに、-vこの値は1ずつ増加します。
しかし、仕事の範囲を教えてくれません。また、使用するかどうかは教えてくれません。
~$ cat ~/.aptitude/config
Verbose "2";
それなら、それはaptitude -v役に立たないのか、役に立たないのか？

Jeff Schallerが言ったように、質問に答えるための最良の方法は、ソースコードを調べることです。以下から最新バージョンを入手できます。
git clone https://anonscm.debian.org/cgit/aptitude/aptitude.git
verbose次に、文字列の発生を見てください。
cd aptitude/src
grep -R verbose *

main.ccでverbose変数が増加していることがわかります。
// Read the arguments:

switch(curopt)

case 'v':
++verbose;
break;
//Other options
これは、コマンドラインオプションにaが表示されるたびにv1ずつ増加することを意味します。ただし、テストした最大値verboseはです。verbose2verbose>=2つまり、-vvコマンドラインでより多くの内容を入力することは役に立ちません。

より直接的にはcmdline_show.hで見ることができます。
* \param verbose How much information to render (scale of 0 to 2 inclusive).
