troff(1)
NAME
troff - typeset or format documents
SYNOPSIS
troff [-a] [-f] [-Fdir] [-i] [-mname] [-nN] [-olist] [-raN]
[-sN] [-Tdest] [-uN] [-z] [filename...]
DESCRIPTION
troff formats text in the filenames for typesetting or laser
printing. Input to troff is expected to consist of text
interspersed with formatting requests and macros. If no
filename argument is present, troff reads standard input. A
minus sign (-) as a filename indicates that standard input
should be read at that point in the list of input files.
The output of troff is usually piped through dpost(1) to
create a printable postscript file (see EXAMPLES).
OPTIONS
The following options are supported. They may appear in any
order, but all must appear before the first filename.
-a Send an ASCII approximation of formatted output to
standard output. (Note: a rough ASCII version can
also be printed out on ordinary terminals with an old
and rarely used command, /usr/bin/ta.)
-f Do not print a trailer after the final page of output
or cause the postprocessor to relinquish control of
the device.
-Fdir Search directory dir for font width or terminal tables
instead of the system default directory.
-i Read standard input after all input files are
exhausted.
-mname
Prepend the macro file /usr/share/lib/tmac/name to the
input filenames. Note: most references to macro pack-
ages include the leading m as part of the name; for
example, the man(5) macros reside in
/usr/share/lib/tmac/an. The macro directory can be
changed by setting the TROFFMACS environment variable
to a specific path. Be certain to include the trailing
'/' (slash) at the end of the path.
-nN Number the first generated page N.
-olist
Print only pages whose page numbers appear in the
comma-separated list of numbers and ranges. A range
N-M means pages N through M; an initial -N means from
the beginning to page N; and a final N- means from N
to the end.
-q Quiet mode in nroff; ignored in troff.
-raN Set register a (one-character names only) to N.
-sN Stop the phototypesetter every N pages. On some dev-
ices, troff produces a trailer so you can change
cassettes; resume by pressing the typesetter's start
button.
-Tdest
Prepare output for typesetter dest. The following
values can be supplied for dest:
post A PostScript printer; this is the default value.
The output of the -T option must go through
dpost(1) before it is sent to a PostScript
printer to obtain the proper output.
aps Autologic APS-5.
-uN Set the emboldening factor for the font mounted in
position 3 to N. If N is missing, then set the embol-
dening factor to 0.
-z Suppress formatted output. Only diagnostic messages
and messages output using the .tm request are output.
OPERANDS
The following operand is supported:
filename
The file containing text to be processed by troff.
EXAMPLES
Example 1: Using troff
The following example shows how to print an input text file
mytext, coded with formatting requests and macros. The input
file contains equations and tables and must go through the
tbl(1) and eqn(1) preprocessors before it is formatted by
troff with ms macros, processed by dpost(1), and printed by
lp(1):
tbl mytext | eqn | troff -ms | dpost | lp

NOTES
troff is not 8-bit clean because it is by design based on
7-bit ASCII.
Previous documentation incorrectly described the numeric
register yr as being the "Last two digits of current year".
yr is in actuality the number of years since 1900. To
correctly obtain the last two digits of the current year
through the year 2099, the definition given below of string
register yy may be included in a document and subsequently
used to display a two-digit year. Note that any other avail-
able one- or two-character register name may be substituted
for yy.
.\" definition of new string register yy--last two digits of year
.\" use yr (# of years since 1900) if it is < 100
.ie \n(yr<100 .ds yy \n(yr
.el \{ .\" else, subtract 100 from yr, store in ny
.nr ny \n(yr-100
.ie \n(ny>9 \{ .\" use ny if it is two digits
.ds yy \n(ny
.\" remove temporary number register ny
.rr ny \}
.el \{.ds yy 0
.\" if ny is one digit, append it to 0
.as yy \n(ny
.rr ny \} \}
