linux aptitude search 结果的字符表示什么意思

Question

用aptitude search搜索后，列表每行前面的字符表示什么意思？
我只知道i是已安装的，p是未安装的
另外问问这类问题怎么搜wiki？man好像没说这个

Answer 1

自答吧，man 里面原来有写——
Each search result is listed on a separate line. The first character of each line indicates the current state
of the package:
the most common states are p, meaning that no trace of the package exists on the system,
c,meaning that the package was deleted but its configuration files remain on the system,
i, meaning that the package is installed,
v, meaning that the package is virtual.

The second character indicates the stored action (if any; otherwise a blank space is displayed) to be performed on the package,
with the most common actions being i, meaning that the package will be installed,
d, meaning that the package will be deleted,
and p, meaning that the package and its configuration files will be removed.
If the third character is A, the package was automatically installed.

For a complete list of the possible state and action flags, see the section “Accessing Package Information” in
the aptitude reference guide.
