MAN(1) BSD Reference Manual MAN(1)
man - display the on-line manual pages
man [-achw] [-C file] [-M path] [-m path] [-S subsection] [-s section] [section] name [...] man -f command man -k keyword
The man utility displays the BSD manual pages entitled name. The options are as follows: -a Display all of the manual pages for a specified section and name combination. (Normally, only the first manual page found is displayed.) -C file Use the specified file instead of the default configuration file. This permits users to configure their own manual environment. See man.conf(5) for a description of the contents of this file. -c Copy the manual page to the standard output instead of using more(1) to paginate it. This is done by default if the standard output is not a terminal device. -f command Locate man pages matching the command in much the same way whatis(1) works. -h Display only the "SYNOPSIS" lines of the requested manual pages. -k keyword Locate man pages matching keyword in much the same way as apropos(1) works (in fact, it runs apropos(1)). This can be used to find which man page applies to a particular subsystem you are interested in. For instance: $ man -k mount will list all man pages which contain keyword in the "NAME" line of the man page; in this case a list much like this: amd (8) - automatically mount file systems amq (8) - automounter query tool mount (8) - mount file systems mount, unmount (2) - mount or dismount a filesystem mount_ados (8) - mount an AmigaDOS file system mount_cd9660 (8) - mount an ISO-9660 filesystem mount_ext2fs (8) - mount a ext2fs file system mount_fdesc (8) - mount the file-descriptor file system mount_ffs, mount_ufs (8) - mount a Berkeley Fast File System mount_kernfs (8) - mount the /kern file system mount_procfs (8) - mount the process file system mount_xfs (8) - mount the xfs filesystem mountd (8) - service remote NFS mount requests newfs, mount_mfs (8) - construct a new file system umount (8) - unmount file systems ... -M path Override the list of standard directories which man searches for manual pages. The supplied path must be a colon (':') separated list of directories. This search path may also be set using the environment variable MANPATH. The subdirectories to be searched, and their search order, are specified by the "_subdir" line in the man configuration file. -m path Augment the list of standard directories which man searches for manual pages. The supplied path must be a colon (':') separated list of directories. These directories will be searched before the standard directories or the directories specified using the -M option or the MANPATH environment variable. The subdirectories to be searched, and their search order, are specified by the "_subdir" line in the man configuration file. -S subsection Specifies the machine-dependent subsection. This overrides the MACHINE environment variable. See the ENVIRONMENT section below. -s section Another way of specifying the section, for compatibility with man on other operating systems. -w List the pathnames of the manual pages which man would display for the specified section and name combination. The optional section argument restricts the directories that man will search. The currently available sections are: 1 General commands (tools and utilities). 2 System calls and error numbers. 3 Libraries. 3p perl(1) programmer's reference guide. 4 Device drivers. 5 File formats. 6 Games. 7 Miscellaneous. 8 System maintenance and operation commands. 9 Kernel internals. The man configuration file (see man.conf(5)) specifies the possible section values, and their search order. If only a single argument is specified, or if the first argument is not a valid section, man assumes that the argument is the name of a manual page to be displayed. Guidelines for OpenBSD man pages can be found in mdoc(7). A full tutorial for writing man pages is provided in mdoc.samples(7).
MACHINE As some manual pages are intended only for specific architec- tures, man searches any subdirectories, with the same name as the current architecture, in every directory which it searches. Machine specific areas are checked before general areas. The current machine type may be overridden by setting the environ- ment variable MACHINE to the name of a specific architecture. MANPAGER Any non-null value of the environment variable MANPAGER will be used instead of the standard pagination program, more(1). MANPATH The standard search path used by man may be overridden by specifying a path in the MANPATH environment variable. The for- mat of the path is a colon (':') separated list of directories. The subdirectories to be searched, as well as their search ord- er, are specified by the "_subdir" line in the man configura- tion file. PAGER Specifies the pagination program to use when MANPAGER is not defined.

The on-line manual pages are, by necessity, forgiving toward stupid display devices, causing a few manual pages to be not as nicely formatted as their typeset counterparts. MirOS BSD #10-current March 9, 1998 2
