troff -man filename...
These macros are used to lay out the reference pages in this manual. Note: if filename contains format input for a preprocessor, the commands shown above must be piped through the appropriate preprocessor. This is handled automatically by the man.1 command. See the ``Conventions'' section.
Any text argument t may be zero to six words. Quotes may be used to include SPACE characters in a ``word''. If text is empty, the special treatment is applied to the next input line with text to be printed. In this way .I may be used to italicize a whole line, or .SB may be used to make small bold letters.
A prevailing indent distance is remembered between successive indented paragraphs, and is reset to default value upon reaching a non-indented paragraph. Default units for indents i are ens.
Type font and size are reset to default values before each paragraph, and after processing font and size setting macros.
These strings are predefined by -man:
Request Cause If no Explanation Break Argument .B t no t=n.t.l.* Text is in bold font. .BI t no t=n.t.l. Join words, alternating bold and italic. .BR t no t=n.t.l. Join words, alternating bold and roman. .DT no .5i 1i... Restore default tabs. .HP i yes i=p.i.* Begin paragraph with hanging indent. Set prevailing indent to i. .I t no t=n.t.l. Text is italic. .IB t no t=n.t.l. Join words, alternating italic and bold. .IP x i yes x="" Same as .TP with tag x. .IR t no t=n.t.l. Join words, alternating italic and roman. .IX t no - Index macro, for SunSoft internal use. .LP yes - Begin left-aligned paragraph. Set prevailing indent to .5i. .P yes - Same as .LP. .PD d no d=.4v Set vertical distance between paragraphs. .PP yes - Same as .LP. .RE yes - End of relative indent. Restores prevailing indent. .RB t no t=n.t.l. Join words, alternating roman and bold. .RI t no t=n.t.l. Join words, alternating roman and italic. .RS i yes i=p.i. Start relative indent, increase indent by i. Sets prevailing indent to .5i for nested in dents. .SB t no - Reduce size of text by 1 point, make text bold. .SH t yes - Section Heading. .SM t no t=n.t.l. Reduce size of text by 1 point. .SS t yes t=n.t.l. Section Subheading. .TH n s d f m yes - Begin reference page n, of of section s; d is the date of the most recent change. If pre sent, f is the left page footer; m is the main page (center) header. Sets prevailing indent and tabs to .5i. .TP i yes i=p.i. Begin indented paragraph, with the tag given on the next text line. Set prevailing indent to i. .TX t p no - Resolve the title abbreviation t; join to punc tuation mark (or text) p.
When formatting a manual page, man examines the first line to determine whether it requires special processing. For example a first line consisting of:
indicates that the manual page must be run through the tbl.1 preprocessor.
A typical manual page for a command or function is laid out as follows:
The syntax of the command and its arguments, as typed on the command line. When in boldface, a word must be typed exactly as printed. When in italics, a word can be replaced with an argument that you supply. References to bold or italicized items are not capitalized in other sections, even when they begin a sentence.
Syntactic symbols appear in roman face:
If required, the data declaration, or #include directive, is shown first, followed by the function declaration. Otherwise, the function declaration is shown.
Literal text from the synopsis appears in constant width, as do literal filenames and references to items that appear elsewhere in the reference manuals. Arguments are italicized.
If a command interprets either subcommands or an input grammar, its command interface or input grammar is normally described in a USAGE section, which follows the OPTIONS section. The DESCRIPTION section only describes the behavior of the command itself, not that of subcommands.
