1：通过man命令"man 5 file.conf"

2: 通过配置文件本身
[root@kook samba]# pwd
/etc/samba
[root@kook samba]# ls
lmhosts  smb.conf
[root@kook samba]# head smb.conf
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
上面的命令已经有答案了。用man 5，看看下面的这个。
[root@kook conf]# pwd
/etc/logwatch/conf
[root@kook conf]# ls
ignore.conf  logfiles  logwatch.conf  override.conf  services
[root@kook conf]# head logwatch.conf
# Local configuration options go here (defaults are in /usr/share/logwatch/default.conf/logwatch.conf)
或者在/user/share这个文档目录里面。

3：总结一下，配置文件如果有相关的解释说明的话，要么出现在man 5里面，要么就存在于rpm包的对应的文档里面。所以可以通过反向来分析得到。
如果知道这个配置文件属于那个rpm包，在看一下rpm包的所有文件。就可以得到结论了。
[root@kook conf]# rpm -qf /etc/file.conf
someone.rpm
[root@kook conf]# rpm -ql someone | less
