LEARN ABOUT MINIX
man
MAN(1) General Commands Manual MAN(1)NAME
man - display online manual pages
SYNOPSIS
man [-antkf] [-M path] [-s section] title ...
DESCRIPTION
Man displays the online manual pages for the specified titles in the specified sections. The sections are as follows:
1 User Commands
Generic commands such as ls, cp, grep.
2 System Calls
Low level routines that directly interface with the kernel.
3 Library Routines
Higher level C language subroutines.
4 Device Files
Describes devices in /dev.
5 File Formats
Formats of files handled by various utilities and subroutines.
6 Games
It's not UNIX without an adventure game.
7 Miscellaneous
Macro packages, miscellaneous tidbits.
8 System Utilities
Commands for the System Administrator.
9 Documents
Larger manuals explaining some commands in more detail.
(If you are new to Minix then try man hier, it will show you around the file system and give you many pointers to other manual pages.)
By default, man will try the following files in a manual page directory for the command man -s 1 ls:
cat1/ls.1
cat1/ls.1.Z
man1/ls.1
man1/ls.1.Z
Files in the man[1-8] directories are formatted with nroff -man. Those in man9 are formatted with nroff -mnx. Files in the cat? directo-
ries are preformatted. Files with names ending in .Z are decompressed first with zcat (see compress(1)). The end result is presented to
the user using a pager if displaying on the screen.
For each manual page directory in its search path, man will first try all the subdirectories of the manual page directory for the files
above, and then the directory itself. The directory /usr/man contains the standard manual pages, with manual pages for optional packages
installed in a subdirectory of /usr/man, with the same structure as /usr/man. The directory /usr/local/man contains manual pages for
locally added software. By default /usr/local/man is searched first, then /usr/man.
A title is not simply used as a filename, because several titles may refer to the same manual page. Each manual page directory contains a
database of titles in the whatis(5) file that is created by makewhatis(8) from the NAME sections of all the manual pages. A title is
searched in this database and the first title on a whatis line is used as a filename.
OPTIONS
The options may be interspersed with the titles to search, and take effect for the titles after them.
-a Show all the manual pages or one line descriptions with the given title in all the specified sections in all the manual directories
in the search path. Normally only the first page found is shown.
-n Use nroff -man to format manual pages (default).
-t Use troff -man to format manual pages.
-f Use whatis(1) to show a one line description of the title from the whatis(5) file.
-k Use apropos(1) to show all the one line descriptions of the title anywhere in the whatis(5) files (implies -a).
-M path
Use path as the search path for manual directories.
-s section
Section is the section number the page is to be found in, or a comma separated list of sections to use. Normally all sections are
searched. The search is always in numerical order no matter what your section list looks like. A single digit is treated as a sec-
tion number without the -s for compatibility with BSD-style man commands.
ENVIRONMENT
MANPATH This is a colon separated list of directories to search for manual pages, by default /usr/local/man:/usr/man.
PAGER The program to use to display the manual page or one line descriptions on the screen page by page. By default more.
FILES
/usr/man/whatis One of the whatis(5) databases.
SEE ALSO nroff(1), troff(1), more(1), whatis(1), makewhatis(1), catman(1), whatis(5), man(7).
