DESCRIPTION man formats and displays the on-line manual pages. If you specify section, man only looks in that section of the manual. name is normally the name of the manual page, which is typically the name of 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. See below for a description of where man looks for the manual page files. 2.2 apropos apropos apropos pass 5
