If you specify section, man only looks in that section of the manual: specify a chapter. Man will only view that chapter.
Name is of a command,function, or file. The name is a command, function, or file
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: if the name contains a slash, man interprets it as a file description, so you can use man. / foo.5 or man / cd/foo/bar.1.gz
