MM(1) — Silicon Graphics

NAME

mm − prints documents formatted with the mm macros

SYNOPSIS

mm [ options ] [ files ]

DESCRIPTION

Use mm to format documents using nroff and the mm text-formatting macro package. mm has options to specify preprocessing by tbl(1) and/or neqn, and postprocessing by various terminal-oriented output filters. The proper pipelines and the required arguments and flags for nroff and mm are generated, depending on the options you select.

Options for mm are given below. Any other arguments or flags (e.g., −rC3) are passed to nroff You may use such options in any order, but you must put them before the files arguments. If you do not specify arguments, mm prints a list of its options.

−Ttty_type
Specifies the type of output terminal. Here is a list of recognized values for tty_type.

2631
Hewlett-Packard 2631 printer in regular mode

2631−c
Hewlett-Packard 2631 printer in compressed mode

2631−e
Hewlett Packard 2631 printer in expanded mode

300
DASI-300 printer

300-12
DASI-300 terminal set to 12-pitch (12 characters per inch)

300s
DASI-300s printer (300S is a synonym)

300s-12
DASI-300s printer set to 12-pitch (12 characters per inch) (300S is a synonym)

37
Teletype Model 37 terminal

382
DTC-382

4000a
Trendata 4000a terminal (4000A is a synonym)

450
DASI-450 (Diablo Hyterm) printer

450-12
DASI-450 terminal set to 12-pitch (12 characters per inch)

832
Anderson Jacobson 832 terminal

8510
C.ITOH printer

tn300
GE Terminet 300 terminal

X
printers equipped with TX print train

lp
generic name for printers that can underline and tab. lp is the default device for mm. All text sent to lp requiring reverse linefeeds, such as those having tables, must be processed with col(1), invoked with mm’s −c option.

If you do not use this option, mm uses the value of the shell variable $TERM from the environment (see environ(5)) as the value of tty_type if $TERM is set; otherwise, mm uses 450 as the value of tty_type. If you specify several terminal types, the last one takes precedence.

−12 indicates that the document is to be produced in 12-pitch. You may use this option when $TERM is set to one of 300, 300s, and 450. (You must manually set the pitch switch on the DASI 300 and 300s terminals to 12 if you use this option).

−c causes mm to invoke col; note that col is invoked automatically by mm unless tty_type is one of 300, 300s, 450, 37, 4000a, 382, and X.

−e Causes mm to invoke neqn; also causes neqn to read the /usr/pub/eqnchar file (see eqnchar(5)).

−t Causes mm to invoke tbl(1).

−E Invokes the −e option of nroff.

As an example (assuming that the shell variable $TERM is set in the environment to 450), the two command lines below are equivalent:

mm −t −rC3 −12 files
tbl files | nroff −mm −T450−12 −h −rC3

mm reads the standard input when you specify − instead of any files. (Mentioning other files together with − leads to undesired results.) This option allows you to use mm as a filter, for example:

cat files | mm −

HINTS

1. Mm invokes nroff with the −h flag. With this flag, nroff assumes that the terminal has tabs set every 8 character positions.

2. Use the −olist option of nroff to specify ranges of pages to be output. Note, however, that if you invoke mm, with one or more of the −e, −t, and − options, together with the −olist option of nroff you may cause a harmless “broken pipe” diagnostic if you do not specify the last page of the document in list.

3. If you use the −s option of nroff (to stop between pages of output), use line-feed (rather than return or new-line) to restart the output. The −s option of nroff does not work with the −c option of mm, or if mm automatically invokes col (see −c option above).

4. If you lie to mm about the kind of terminal its output will be printed on, you will get (often subtle) garbage; however, if you are redirecting output into a file, use the −T37 option, and then use the appropriate terminal filter when you actually print that file.
