man [-acdDfFhkKtvVwW] [--path] [-m system] [-p string] [-C config_file] [-M pathlist] [-P pager] [-B browser] [-H htmlpager] [-S section_list] [section] name ...
DESCRIPTION:
man formats and displays the on-line manual pages :格式化显示在线手册页
if you specify section, man only looks in that section of the manual:指定章节，man只查看那章
name is of a command,function, or file. 名字是一个命令、功能、或者文件
However ，if name contains a slash (/) then man interprets it as a file specification,so that you can do man ./foo.5 or even man /cd/foo/bar.1.gz :如果name中包含斜杠，man将他解释为文件说明，所以，你可以使用man ./foo.5 或者 man /cd/foo/bar.1.gz
see below for description of where man looks for the manual page files
