troff(1)                         User Commands                        troff(1)

       troff - typeset or format documents

       troff  [-a]  [-f]  [-Fdir]  [-i]  [-mname]  [-nN] [-olist] [-raN] [-sN]
       [-Tdest] [-uN] [-z] [filename...]

       troff formats text in the filenames for typesetting or laser  printing.
       Input to troff is expected to consist of text interspersed with format-
       ting 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).

       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

       -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

       -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
                       devices,  troff  produces  a  trailer so you can change
                       cassettes; resume by pressing  the  typesetter's  start

       -Tdest          Prepare  output for typesetter dest. The following val-
                       ues 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  Post-
                                Script 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  embold-
                       ening factor to 0.

       -z              Suppress formatted output. Only diagnostic messages and
                       messages output using the .tm request are output.

       The following operand is supported:

       filename        The file containing text to be processed by troff.

       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)  pre-
       processors 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

       /tmp/trtmp                      temporary file

       /usr/share/lib/tmac/*           standard macro files

       /usr/lib/font/*                 font width tables for alternate mounted
                                       troff fonts

       /usr/share/lib/nterm/*          terminal driving tables for nroff

       See attributes(5) for descriptions of the following attributes:

       tab()     allbox;     cw(2.750000i)|    cw(2.750000i)    lw(2.750000i)|
       lw(2.750000i).  ATTRIBUTE TYPEATTRIBUTE VALUE AvailabilitySUNWdoc

       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 available 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 \} \}
