groff_man(7) Miscellaneous Information Manual groff_man(7)
Name
groff_man - compose manual pages with GNU roff
Synopsis
groff -man [option ...] [file ...]
groff -m man [option ...] [file ...]
Description
The GNU implementation of the man macro package is part of the groff
document formatting system. It is used to produce manual pages
("man pages") like the one you are reading.
This document presents the macros thematically; for those needing only
a quick reference, the following table lists them alphabetically, with
cross references to appropriate subsections below.
Man page authors and maintainers who are not already experienced groff
users should consult groff_man_style(7), an expanded version of this
document, for additional explanations and advice. It covers only those
concepts required for man page document maintenance, and not the full
breadth of the groff typesetting system.

We discuss other macros (.AT, .DT, .HP, .OP, .PD, and .UC) in
subsection "Deprecated features" below.
Throughout Unix documentation, a manual entry is referred to simply as
a "man page", regardless of its length, without gendered implication,
and irrespective of the macro package selected for its composition.
Macro reference preliminaries
A tagged paragraph describes each macro. We present coupled pairs
together, as with .EX and .EE.
An empty macro argument can be specified with a pair of double-quotes
(""), but the man package is designed such that this should seldom be
necessary. Most macro arguments will be formatted as text in the
output; exceptions are noted.
Document structure macros
Document structure macros organize a man page's content. All of them
break the output line. .TH (title heading) identifies the document as
a man page and configures the page headers and footers. Section
headings (.SH), one of which is mandatory and many of which are
conventionally expected, facilitate location of material by the reader
and aid the man page writer to discuss all essential aspects of the
topic. Subsection headings (.SS) are optional and permit sections that
grow long to develop in a controlled way. Many technical discussions
benefit from examples; lengthy ones, especially those reflecting
multiple lines of input to or output from the system, are usefully
bracketed by .EX and .EE. When none of the foregoing meets a
structural demand, use .RS/.RE to inset a region within a (sub)section.
.TH topic section [footer-middle] [footer-inside] [header-middle]
Determine the contents of the page header and footer. The
subject of the man page is topic and the section of the manual
to which it belongs is section. See man(1) or intro(1) for the
manual sectioning applicable to your system. topic and section
are positioned together at the left and right in the header
(with section in parentheses immediately appended to topic).
footer-middle is centered in the footer. The arrangement of the
rest of the footer depends on whether double-sided layout is
enabled with the option -rD1. When disabled (the default),
footer-inside is positioned at the bottom left. Otherwise,
footer-inside appears at the bottom left on recto (odd-numbered)
pages, and at the bottom right on verso (even-numbered) pages.
The outside footer is the page number, except in the continuous-
rendering mode enabled by the option -rcR=1, in which case it is
the topic and section, as in the header. header-middle is
centered in the header. If section is an integer between 1
and 9 (inclusive), there is no need to specify header-middle;
an.tmac will supply text for it. The macro package may also
abbreviate topic and footer-inside with ellipses if they would
overrun the space available in the header and footer,
respectively. For HTML output, headers and footers are
suppressed.
Additionally, this macro breaks the page, resetting the number
to 1 (unless the -rC1 option is given). This feature is
intended only for formatting multiple man documents in sequence.
A valid man document calls .TH once, early in the file, prior to
any other macro calls.
.SH [heading-text]
Set heading-text as a section heading. If no argument is given,
a one-line input trap is planted; text on the next line becomes
heading-text. The left margin is reset to zero to set the
heading text in bold (or the font specified by the string HF),
and, on typesetting devices, slightly larger than the base type
size. If the heading font \*[HF] is bold, use of an italic
style in heading-text is mapped to the bold-italic style if
available in the font family. The inset level is reset to 1,
setting the left margin to the value of the IN register. Text
after heading-text is set as an ordinary paragraph (.P).
The content of heading-text and ordering of sections follows a
set of common practices, as has much of the layout of material
within sections. For example, a section called "Name" or "NAME"
must exist, must be the first section after the .TH call, and
must contain only text of the form
topic[, another-topic]... \- summary-description
for a man page to be properly indexed. See groff_man_style(7)
for suggestions and man(7) for the conventions prevailing on
your system.
.SS [subheading-text]
Set subheading-text as a subsection heading indented between a
section heading and an ordinary paragraph (.P). If no argument
is given, a one-line input trap is planted; text on the next
line becomes subheading-text. The left margin is reset to the
value of the SN register to set the heading text in bold (or the
font specified by the string HF). If the heading font \*[HF] is
bold, use of an italic style in subheading-text is mapped to the
bold-italic style if available in the font family. The inset
level is reset to 1, setting the left margin to the value of the
IN register. Text after subheading-text is set as an ordinary
paragraph (.P).
.EX
.EE Begin and end example. After .EX, filling is disabled and a
constant-width (monospaced) font is selected. Calling .EE
enables filling and restores the previous font.
These macros are extensions introduced in Ninth Edition Research
Unix. Systems running that troff, or those from Documenter's
Workbench, Heirloom Doctools, or Plan 9 troff support them. To
be certain your page will be portable to systems that do not,
copy their definitions from the an-ext.tmac file of a groff
installation.
.RS [inset-amount]
Start a new relative inset level. The position of the left
margin is saved, then moved right by inset-amount, if specified,
and by the amount of the IN register otherwise. Calls to .RS
can be nested; each increments by 1 the inset level used by .RE.
The level prior to any .RS calls is 1.
.RE [level]
End a relative inset. The left margin corresponding to inset
level level is restored. If no argument is given, the inset
level is reduced by 1.
Paragraphing macros
An ordinary paragraph (.P) is set without a first-line indentation at
the current left margin. In man pages and other technical literature,
definition lists are frequently encountered; these can be set as
"tagged paragraphs", which have one (.TP) or more (.TQ) leading tags
followed by a paragraph that has an additional indentation. The
indented paragraph (.IP) macro is useful to continue the indented
content of a narrative started with .TP, or to present an itemized or
ordered list. All of these macros break the output line. If another
paragraph macro has occurred since the previous .SH or .SS, they
(except for .TQ) follow the break with a default amount of vertical
space, which can be changed by the deprecated .PD macro; see subsection
"Horizontal and vertical spacing" below. They also reset the type size
and font style to defaults (.TQ again excepted); see subsection "Font
style macros" below.
.P
.LP
.PP Begin a new paragraph; these macros are synonymous. The
indentation is reset to the default value; the left margin, as
affected by .RS and .RE, is not.
.TP [indentation]
Set a paragraph with a leading tag, and the remainder of the
paragraph indented. A one-line input trap is planted; text on
the next line, which can be formatted with a macro, becomes the
tag, which is placed at the current left margin. The tag can be
extended with the \c escape sequence. Subsequent text is
indented by indentation, if specified, and by the amount of the
IN register otherwise. If the tag is not as wide as the
indentation, the paragraph starts on the same line as the tag,
at the applicable indentation, and continues on the following
lines. Otherwise, the descriptive part of the paragraph begins
on the line following the tag.
.TQ Set an additional tag for a paragraph tagged with .TP. An input
trap is planted as with .TP.
This macro is a GNU extension not defined on systems running
AT&T, Plan 9, or Solaris troff; see an-ext.tmac in section
"Files" below.
.IP [tag] [indentation]
Set an indented paragraph with an optional tag. The tag and
indentation arguments, if present, are handled as with .TP, with
the exception that the tag argument to .IP cannot include a
macro call.
Command synopsis macros
.SY and .YS aid you to construct a command synopsis that has the
classical Unix appearance. They break the output line.
These macros are GNU extensions not defined on systems running AT&T,
Plan 9, or Solaris troff; see an-ext.tmac in section "Files" below.
.SY command
Begin synopsis. A new paragraph begins at the left margin
unless .SY has already been called without a corresponding .YS,
in which case only a break is performed. Adjustment and
automatic hyphenation are disabled. command is set in bold. If
a break is required, lines after the first are indented by the
width of command plus a space.
.YS End synopsis. Indentation, adjustment, and hyphenation are
restored to their previous states.
Hyperlink macros
Man page cross references are best presented with .MR. Text may be
hyperlinked to email addresses with .MT/.ME or other URIs with .UR/.UE.
Hyperlinked text is supported on HTML and terminal output devices;
terminals and pager programs must support ECMA-48 OSC 8 escape
sequences (see grotty(1)). When device support is unavailable or
disabled with the U register (see section "Options" below), .MT and .UR
URIs are rendered between angle brackets after the linked text.
.MT, .ME, .UR, and .UE are GNU extensions not defined on systems
running AT&T, Plan 9, or Solaris troff; see an-ext.tmac in section
"Files" below. Plan 9 from User Space's troff implements .MR.
The arguments to .MR, .MT, and .UR should be prepared for typesetting
since they can appear in the output. Use special character escape
sequences to encode Unicode basic Latin characters where necessary,
particularly the hyphen-minus. The formatter removes \: escape
sequences from hyperlinks when supplying device control commands to
output drivers.
.MR topic manual-section [trailing-text]
(since groff 1.23) Set a man page cross reference as
"topic(manual-section)". If trailing-text (typically
punctuation) is specified, it follows the closing parenthesis
without intervening space. Hyphenation is disabled while the
cross reference is set. topic is set in the font specified by
the MF string. The cross reference hyperlinks to a URI of the
form "man:topic(manual-section)".
.MT address
.ME [trailing-text]
Identify address as an RFC 6068 addr-spec for a "mailto:" URI
with the text between the two macro calls as the link text. An
argument to .ME is placed after the link text without
intervening space. address may not be visible in the rendered
document if hyperlinks are enabled and supported by the output
driver. If they are not, address is set in angle brackets after
the link text and before trailing-text. If hyperlinking is
enabled but there is no link text, address is formatted and
hyperlinked without angle brackets.
.UR uri
.UE [trailing-text]
Identify uri as an RFC 3986 URI hyperlink with the text between
the two macro calls as the link text. An argument to .UE is
placed after the link text without intervening space. uri may
not be visible in the rendered document if hyperlinks are
enabled and supported by the output driver. If they are not,
uri is set in angle brackets after the link text and before
trailing-text. If hyperlinking is enabled but there is no link
text, uri is formatted and hyperlinked without angle brackets.
The hyperlinking of .TP paragraph tags with .UR/.UE and .MT/.ME is not
yet supported; if attempted, the hyperlink will be typeset at the
beginning of the indented paragraph even on hyperlink-supporting
devices.
Font style macros
The man macro package is limited in its font styling options, offering
only bold (.B), italic (.I), and roman. Italic text is usually set
underscored instead on terminal devices. The .SM and .SB macros set
text in roman or bold, respectively, at a smaller type size; these
differ visually from regular-sized roman or bold text only on
typesetting devices. It is often necessary to set text in different
styles without intervening space. The macros .BI, .BR, .IB, .IR, .RB,
and .RI, where "B", "I", and "R" indicate bold, italic, and roman,
respectively, set their odd- and even-numbered arguments in alternating
styles, with no space separating them.
The default type size and family for typesetting devices is 10-point
Times, except on the X75-12 and X100-12 devices where the type size is
12 points. The default style is roman.
.B [text]
Set text in bold. If no argument is given, a one-line input
trap is planted; text on the next line, which can be further
formatted with a macro, is set in bold.
.I [text]
Set text in an italic or oblique face. If no argument is given,
a one-line input trap is planted; text on the next line, which
can be further formatted with a macro, is set in an italic or
oblique face.
.SM [text]
Set text one point smaller than the default type size on
typesetting devices. If no argument is given, a one-line input
trap is planted; text on the next line, which can be further
formatted with a macro, is set smaller.
.SB [text]
Set text in bold and (on typesetting devices) one point smaller
than the default type size. If no argument is given, a one-line
input trap is planted; text on the next line, which can be
further formatted with a macro, is set smaller and in bold.
This macro is an extension introduced in SunOS 4.0.
Unlike the above font style macros, the font style alternation macros
below set no input traps; they must be given arguments to have effect.
Italic corrections are applied as appropriate.
.BI bold-text italic-text ...
Set each argument in bold and italics, alternately.
.BR bold-text roman-text ...
Set each argument in bold and roman, alternately.
.IB italic-text bold-text ...
Set each argument in italics and bold, alternately.
.IR italic-text roman-text ...
Set each argument in italics and roman, alternately.
.RB roman-text bold-text ...
Set each argument in roman and bold, alternately.
.RI roman-text italic-text ...
Set each argument in roman and italics, alternately.
Horizontal and vertical spacing
The indentation argument accepted by .IP, .TP, and the deprecated .HP
is a number plus an optional scaling unit, as is .RS's inset-amount.
If no scaling unit is given, the man package assumes "n". An
indentation specified in a call to .IP, .TP, or the deprecated .HP
persists until (1) another of these macros is called with an
indentation argument, or (2) .SH, .SS, or .P or its synonyms is called;
these clear the indentation entirely.
The left margin used by ordinary paragraphs set with .P (and its
synonyms) not within an .RS/.RE relative inset is 7.2n for typesetting
devices and 7n for terminal devices (but see the -rIN option).
Headers, footers (both set with .TH), and section headings (.SH) are
set at the page offset (see groff(7)) and subsection headings (.SS)
indented from it by 3n (but see the -rSN option).
Several macros insert vertical space: .SH, .SS, .TP, .P (and its
synonyms), .IP, and the deprecated .HP. The default inter-section and
inter-paragraph spacing is is 1v for terminal devices and 0.4v for
typesetting devices. (The deprecated macro .PD can change this
vertical spacing, but its use is discouraged.) Between .EX and .EE
calls, the inter-paragraph spacing is 1v regardless of output device.
Registers
Registers are described in section "Options" below. They can be set
not only on the command line but in the site man.local file as well;
see section "Files" below.
Strings
The following strings are defined for use in man pages. None of these
is necessary in a contemporary man page; see groff_man_style(7).
Others are supported for configuration of rendering parameters; see
section "Options" below.
\*R interpolates a special character escape sequence for the
"registered sign" glyph, \(rg, if available, and "(Reg.)"
otherwise.
\*S interpolates an escape sequence setting the type size to the
document default.
\*(lq
\*(rq interpolate special character escape sequences for left and
right double-quotation marks, \(lq and \(rq, respectively.
\*(Tm interpolates a special character escape sequence for the "trade
mark sign" glyph, \(tm, if available, and "(TM)" otherwise.
Hooks
Two macros, both GNU extensions, are called internally by the groff man
package to format page headers and footers and can be redefined by the
administrator in a site's man.local file (see section "Files" below).
The presentation of .TH above describes the default headers and
footers. Because these macros are hooks for groff man internals, man
pages have no reason to call them. Such hook definitions will likely
consist of ".sp" and ".tl" requests. They must also increase the page
length with ".pl" requests in continuous rendering mode; .PT
furthermore has the responsibility of emitting a PDF bookmark after
writing the first page header in a document. Consult the existing
implementations in an.tmac when drafting replacements.
.BT Set the page footer text ("bottom trap").
.PT Set the page header text ("page trap").
To remove a page header or footer entirely, define the appropriate
macro as empty rather than deleting it.
Deprecated features
Use of the following in man pages for public distribution is
discouraged.
.AT [system [release]]
Alter the footer for use with legacy AT&T man pages, overriding
any definition of the footer-inside argument to .TH. This macro
exists only to render man pages from historical systems.
system can be any of the following.
3 7th edition (default)
4 System III
5 System V
The optional release argument specifies the release number, as
in "System V Release 3".
.DT Reset tab stops to the default (every 0.5i).
Use of this presentation-oriented macro is deprecated. It
translates poorly to HTML, under which exact space control and
tabulation are not readily available. Thus, information or
distinctions that you use tab stops to express are likely to be
lost. If you feel tempted to change the tab stops such that
calling this macro later is desirable to restore them, you
should probably be composing a table using tbl(1) instead.
.HP [indentation]
Set up a paragraph with a hanging left indentation. The
indentation argument, if present, is handled as with .TP.
Use of this presentation-oriented macro is deprecated. A
hanging indentation cannot be expressed naturally under HTML,
and non-roff-based man page interpreters may treat .HP as an
ordinary paragraph. Thus, information or distinctions you mean
to express with indentation may be lost.
.OP option-name [option-argument]
Indicate an optional command parameter called option-name, which
is set in bold. If the option takes an argument, specify
option-argument using a noun, abbreviation, or hyphenated noun
phrase. If present, option-argument is preceded by a space and
set in italics. Square brackets in roman surround both
arguments.
Use of this quasi-semantic macro, an extension originating in
Documenter's Workbench troff, is deprecated. It cannot easily
be used to annotate options that take optional arguments or
options whose arguments have internal structure (such as a
mixture of literal and variable components). One could work
around these limitations with font selection escape sequences,
but it is preferable to use font style alternation macros, which
afford greater flexibility.
.PD [vertical-space]
Define the vertical space between paragraphs or (sub)sections.
The optional argument vertical-space specifies the amount; the
default scaling unit is "v". Without an argument, the spacing
is reset to its default value; see subsection "Horizontal and
vertical spacing" above.
Use of this presentation-oriented macro is deprecated. It
translates poorly to HTML, under which exact control of inter-
paragraph spacing is not readily available. Thus, information
or distinctions that you use .PD to express are likely to be
lost.
.UC [version]
Alter the footer for use with legacy BSD man pages, overriding
any definition of the footer-inside argument to .TH. This macro
exists only to render man pages from historical systems.
version can be any of the following.
3 3rd Berkeley Distribution (default)
4 4th Berkeley Distribution
5 4.2 Berkeley Distribution
6 4.3 Berkeley Distribution
7 4.4 Berkeley Distribution
History
M. Douglas McIlroy <m.douglas.mcilroy@dartmouth.edu> designed,
implemented, and documented the AT&T man macros for Unix Version 7
(1979) and employed them to edit the first volume of its Programmer's
Manual, a compilation of all man pages supplied by the system. That
man supported the macros listed in this page not described as
extensions, except .P and the deprecated .AT and .UC. The only strings
defined were R and S; no registers were documented.
.UC appeared in 3BSD (1980). Unix System III (1980) introduced .P and
exposed the registers IN and LL, which had been internal to Seventh
Edition Unix man. PWB/UNIX 2.0 (1980) added the Tm string. 4BSD
(1980) added lq and rq strings. SunOS 2.0 (1985) recognized C, D, P,
and X registers. 4.3BSD (1986) added .AT and .P. Ninth Edition
Research Unix (1986) introduced .EX and .EE. SunOS 4.0 (1988) added
.SB.
The foregoing features were what James Clark implemented in early
versions of groff. Later, groff 1.20 (2009) originated .SY/.YS, .TQ,
.MT/.ME, and .UR/.UE. Plan 9 from User Space's troff introduced .MR in
2020.
Options
The following groff options set registers (with -r) and strings (with
-d) recognized and used by the man macro package. To ensure rendering
consistent with output device capabilities and reader preferences, man
pages should never manipulate them.
-dAD=adjustment-mode
Set line adjustment to adjustment-mode, which is typically "b"
for adjustment to both margins (the default), or "l" for left
alignment (ragged right margin). Any valid argument to groff's
".ad" request may be used. See groff(7) for less-common
choices.
-rcR=1 Enable continuous rendering. Output is not paginated; instead,
one (potentially very long) page is produced. This is the
default for terminal and HTML devices. Use -rcR=0 to disable it
on terminal devices; on HTML devices, it cannot be disabled.
-rC1 Number output pages consecutively, in strictly increasing
sequence, rather than resetting the page number to 1 (or the
value of register P) with each new man document.
-rCS=1 Set section headings (the argument(s) to .SH) in full capitals.
This transformation is off by default because it discards case
distinction information.
-rCT=1 Set the man page topic (the first argument to .TH) in full
capitals in headers and footers. This transformation is off by
default because it discards case distinction information.
-rD1 Enable double-sided layout, formatting footers for even and odd
pages differently; see the description of .TH in subsection
"Document structure macros" above.
-rFT=footer-distance
Set distance of the footer relative to the bottom of the page to
footer-distance; this amount is always negative. At one half-
inch above this location, the page text is broken before writing
the footer. Ignored if continuous rendering is enabled. The
default is -0.5i.
-dHF=heading-font
Set the font used for section and subsection headings; the
default is "B" (bold style of the default family). Any valid
argument to groff's ".ft" request may be used. See groff(7).
-rHY=0 Disable automatic hyphenation. Normally, it is enabled (1).
The hyphenation mode is determined by the groff locale; see
section "Localization" of groff(7).
-rIN=standard-indentation
Set the amount of indentation used for ordinary paragraphs (.P
and its synonyms) and the default indentation amount used by
.IP, .RS, .TP, and the deprecated .HP. See subsection
"Horizontal and vertical spacing" above for the default. For
terminal devices, standard-indentation should always be an
integer multiple of unit "n" to get consistent indentation.
-rLL=line-length
Set line length; the default is 78n for terminal devices and
6.5i for typesetting devices.
-rLT=title-length
Set the line length for titles. By default, it is set to the
line length (see -rLL above).
-dMF=man-page-topic-font
Set the font used for man page topics named in .TH and .MR
calls; the default is "I" (italic style of the default family).
Any valid argument to groff's ".ft" request may be used. If the
MF string ends in "I", it is assumed to be an oblique typeface,
and italic corrections are applied before and after man page
topics.
-rPn Start enumeration of pages at n. The default is 1.
-rStype-size
Use type-size for the document's body text; acceptable values
are 10, 11, or 12 points. See subsection "Font style macros"
above for the default.
-rSN=subsection-indentation
Set indentation of subsection headings to
subsection-indentation. See subsection "Horizontal and vertical
spacing" above for the default.
-rU1 Enable generation of URI hyperlinks in the grohtml and grotty
output drivers. grohtml enables them by default; grotty does
not, pending more widespread pager support for OSC 8 escape
sequences. Use -rU0 to disable hyperlinks; this will make the
arguments to MT and UR calls visible in the document text
produced by link-capable drivers.
-rXp Number successors of page p as pa, pb, pc, and so forth. The
register tracking the suffixed page letter uses format "a" (see
the ".af" request in groff(7)).
Files
/opt/local/share/groff/1.23.0/tmac/an.tmac
Most man macros are defined in this file. It also loads
extensions from an-ext.tmac (see below).
/opt/local/share/groff/1.23.0/tmac/andoc.tmac
This brief groff program detects whether the man or mdoc macro
package is being used by a document and loads the correct macro
definitions, taking advantage of the fact that pages using them
must call .TH or .Dd, respectively, before any other macros. A
man program or user typing, for example, "groff -mandoc page.1",
need not know which package the file page.1 uses. Multiple man
pages, in either format, can be handled; andoc reloads each
macro package as necessary.
/opt/local/share/groff/1.23.0/tmac/an-ext.tmac
Except for .SB, definitions of macros described above as
extensions are contained in this file; in some cases, they are
simpler versions of definitions appearing in an.tmac, and are
ignored if the formatter is GNU troff. They are written to be
compatible with AT&T troff and permissively licensed--not
copylefted. To reduce the risk of name space collisions, string
and register names begin only with "m". We encourage man page
authors who are concerned about portability to legacy Unix
systems to copy these definitions into their pages, and
maintainers of troff implementations or work-alike systems that
format man pages to re-use them.
The definitions for these macros are read after a page calls
.TH, so they will replace any macros of the same names preceding
it in your file. If you use your own implementations of these
macros, they must be defined after .TH is called to have any
effect. Furthermore, it is wise to define such page-local
macros (if at all) after the "Name" section to accommodate timid
makewhatis or mandb implementations that may give up their scan
for indexing material early.

Authors
The initial GNU implementation of the man macro package was written by
James Clark. Later, Werner Lemberg <wl@gnu.org> supplied the S, LT,
and cR registers, the last a 4.3BSD-Reno mdoc(7) feature. Larry Kollar
<kollar@alltel.net> added the FT, HY, and SN registers; the HF string;
and the PT and BT macros. G. Branden Robinson <g.branden.robinson@
gmail.com> implemented the AD and MF strings; CS, CT, and U registers;
and the MR macro. Except for .SB, the extension macros were written by
Lemberg, Eric S. Raymond <esr@thyrsus.com>, and Robinson.
This document was originally written for the Debian GNU/Linux system by
Susan G. Kleinmann <sgk@debian.org>. It was corrected and updated by
Lemberg and Robinson. The extension macros were documented by Raymond
and Robinson.
