SYNOPSIS
man [-acdfFhkKtwW] [--path] [-m system] [-p string] [-C config_file] [-M pathlist] [-P pager] [-B browser] [-H htmlpager] [-S section_list] [section] name ...


DESCRIPTION



OPTIONS
-C config_file
Specify the configuration file to use; the default is /etc/man.config. (See man.config(5).)

-M path
Specify the list of directories to search for man pages. Separate the directories with colons. An empty list is the same as not specifying -M at all. See SEARCH PATH FOR MANUAL PAGES.

-P pager
Specify which pager to use. This option overrides the MANPAGER environment variable, which in turn overrides the PAGER variable. By default, man uses /usr/bin/less -is.

-B
Specify which browser to use on HTML files. This option overrides the BROWSER environment variable. By default, man uses /usr/bin/less-is,

-H
Specify a command that renders HTML files as text. This option overrides the HTMLPAGER environment variable. By default, man uses /bin/cat,

-S section_list
List is a colon separated list of manual sections to search. This option overrides the MANSECT environment variable.

-a
By default, man will exit after displaying the first manual page it finds. Using this option forces man to display all the manual pages that match name, not just the first.

-c
Reformat the source man page, even when an up-to-date cat page exists. This can be meaningful if the cat page was formatted for a screen with a different number of columns, or if the preformatted page is corrupted.

-d
Don't actually display the man pages, but do print gobs of debugging information.

-D
Both display and print debugging info.

-f
Equivalent to whatis.

-F or --preformat
Format only - do not display.

-h
Print a help message and exit.

-k
Equivalent to apropos.

-K
Search for the specified string in *all* man pages. Warning: this is probably very slow! It helps to specify a section. (Just to give a rough idea, on my machine this takes about a minute per 500 man pages.)

-m system
Specify an alternate set of man pages to search based on the system name given.

-p string
Specify the sequence of preprocessors to run before nroff or troff. Not all installations will have a full set of preprocessors. Some of the preprocessors and the letters used to desig- nate them are: eqn (e), grap (g), pic (p), tbl (t), vgrind (v), refer (r). This option overrides the MANROFFSEQ environment variable.

-t
Use /usr/bin/groff -Tps -mandoc to format the manual page, passing the output to stdout. The default output format of /usr/bin/groff -Tps -mandoc is Postscript, refer to the manual page of /usr/bin/groff -Tps -mandoc for ways to pick an alternate format.

Depending on the selected format and the availability of printing devices, the output may need to be passed through some filter or another before being printed.

-w or --path
Don't actually display the man pages, but do print the location(s) of the files that would be formatted or displayed. If no argument is given: display (on stdout) the list of directories that is searched by man for man pages. If manpath is a link to man, then "manpath" is equivalent to "man --path".

-W
Like -w, but print file names one per line, without additional information. This is useful in shell commands like man -aW man | xargs ls -l
