# man man 
...
       The table below shows the section numbers of the manual followed by the types of pages they contain.

       1   Executable programs or shell commands
       2   System calls (functions provided by the kernel)
       3   Library calls (functions within program libraries)
       4   Special files (usually found in /dev)
       5   File formats and conventions eg /etc/passwd
       6   Games
       7   Miscellaneous (including macro packages and conventions), e.g. man(7), groff(7)
       8   System administration commands (usually only for root)
       9   Kernel routines [Non standard]
...

所以，man man 等于 man 1 man。

# rpm -qa | while read line ; do rpm -ql $line | grep -q man[1-9] && echo $line  ; done

打印所有包含man文档的软件包，实际比想象的要包很多。
