.SH DESCRIPTION

\f3Enscript\f1 converts text files to PostScript or to other output
languages.  \f3Enscript\f1 can spool the generated output directly to
a specified printer or leave it to a file.  If no input files are
given, \f3enscript\f1 processes the standard input \f3stdin\f1.
\f3Enscript\f1 can be extended to handle different output media and it
has many options which can be used to customize the printouts.

.SH OPTIONS
.TP 8
.B \-# \f2num\f3
Print \f2num\f1 copies of each page.
.TP 8
.B \-1, \-2, \-3, \-4, \-5, \-6, \-7, \-8, \-9, \-\-columns=\f2num\f3
Specify how many columns each page have.  With the long option
\f3\-\-columns=\f2num\f1 you can specify more than 9 columns per page.
.TP 8
.B \-a \f2pages\f3, \-\-pages=\f2pages\f3
Specify which pages are printed.  The page specification \f2pages\f1
can be given in the following formats:
.RS 8
.TP 8
\f2begin\f1\-\f2end\f1
print pages from \f2begin\f1 to \f2end\f1
.TP 8
\-\f2end\f1
print pages from 0 to \f2end\f1
.TP 8
\f2begin\f1\-
print pages from \f2begin\f1 to end
.TP 8
\f2page\f1
print page \f2page\f1
.TP 8
odd
print odd pages
.TP 8
even
print even pages
.RE
.TP 8
.B \-A \f2align\f3, \-\-file\-align=\f2align\f3
Align separate input files to even \f2align\f1 page count.  This
option is useful in two-side and 2-up printings (\-\-file\-align=2).
.TP 8
.B \-b \f2header\f3, \-\-header=\f2header\f3
Use the text \f2header\f1 as a page header.  The default page header
is constructed from the name of the file and from its last
modification time.

The header string \f2header\f1 can contain the same formatting escapes
which can be specified for the \f3%Format\f1 directives in the user
defined fancy headers.  For example, the following option prints the
file name, current date and page numbers:

\f3enscript \-\-header='$n %W Page $% of $=' *.c\f1

The header string can also contain left, center and right justified
fields.  The fields are separated by the \f3'|'\f1 character:

\f3enscript \-\-header='$n|%W|Page $% of $=' *.c\f1

now the file name is printed left justified, the date is centered to
the header and the page numbers are printed right justified.
.TP 8
.B \-B, \-\-no\-header
Do not print page headers.
.TP 8
.B \-c, \-\-truncate\-lines
Cut lines that are too long for the page.  As a default,
\f3enscript\f1 wraps long lines to the next line so no information is
lost.

You can also use the \f3\-\-slice\f1 option which slices long lines to
separate pages.
.TP 8
.B \-C\f1[\f2start_line\f1]\f3, \-\-line\-numbers\f1[\f3=\f2start_line\f1]\f3
Precede each line with its line number.  The optional argument
\f2start_line\f1 specifies the number of the first line in the input.
The number of the first line defaults to 1.
.TP 8
.B \-d \f2name\f3
Spool output to the printer \f2name\f1.
.TP 8
.B \-D \f2key\f1[\f3:\f2value\f1]\f3, \-\-setpagedevice=\f2key\f1[\f3:\f2value\f1]\f3
Pass a page device definition to the generated PostScript output.  If
no value is given, the key \f2key\f1 is removed from the definitions.

For example, the command

.B enscript \-DDuplex:true foo.txt

prints file foo.txt in duplex (two side) mode.

Page device operators are implementation dependent but they are
standardized.  See section \f3PAGE DEVICE OPTIONS\f1 for the details.
.TP 8
.B \-e\f1[\f2char\f1]\f3, \-\-escapes\f1[\f3=\f2char\f1]\f3
Enable special escapes interpretation (see section \f3SPECIAL
ESCAPES\f1).  If the argument \f2char\f1 is given, it changes the
escape character to \f2char\f1.  The default escape character is 0.
.TP 8
.B \-E\f1[\f2lang\f1]\f3, \-\-highlight\f1[\f3=\f2lang\f1]\f3
Highlight source code by creating a special input filter with the
\f3states\f1 program.  The optional argument \f2lang\f1 specifies the
language to highlight.  As a default the \f3states\f1 makes an
educated guess.

You can print a short description of the supported highlighting
languages and file formats with the command:

.B enscript \-\-help\-highlight

The highlighting rules are defined in the
`@DATADIR@/enscript/hl/*.st' files which can be edited to create
highlighting definitions for new languages.

\f3Note!\f1 You can not use your own input filters with this option.
.TP 8
.B \-f \f2name\f3, \-\-font=\f2name\f3
Select a font that is used for the body text.  The default body font is
\f3Courier10\f1, unless multicolumn landscape printing mode is
selected, in which case the default font is \f3Courier7\f1.

The font specification \f2name\f1 contains two parts: the name of the
font and its size in PostScript points.  For example,
"\f3Times\-Roman12\f1" selects the "Times\-Roman" font with size
12pt.

The font specification \f2name\f1 can also be given in format
`\f2name\f1@\f2ptsize\f1', where the name of the font and its point
size are separated by a `@' character.  This allows \f3enscript\f1 to use
fonts which contain digit characters in their names.

The font point size can also be given in the format
\f2width\f1/\f2height\f1 where the \f2width\f1 and the \f2height\f1
specify the size of the font in x- and y-directions.  For example,
"\f3Times\-Roman@10/12\f1" selects a 10 points wide and 12 points high
"Times\-Roman" font.

You can also give the font sizes as decimal numbers.  For example,
"\f3Times\-Roman10.2\f1" selects a 10.2pt "Times\-Roman" font.
.TP 8
.B \-F \f2name\f3, \-\-header\-font=\f2name\f3
Select a font for the header texts.
.TP 8
.B \-g, \-\-print\-anyway
Print a file even if it contains binary data.  The option is
implemented only for compatibility purposes.  \f3Enscript\f1 prints
binary files anyway regardless of the option.
.TP 8
.B \-G, \-\-fancy\-header\f1[\f3=\f2name\f1]\f3
Print a fancy page header \f2name\f1 to the top of each page.  The
option \f3\-G\f1 specifies the default fancy header.  See section
\f3CONFIGURATION FILES\f1 to see how the default fancy header can be
changed.
.TP 8
.B \-h, \-\-no\-job\-header
Suppress printing of the job header page.
.TP 8
.B \-H\f1[\f2num\f1]\f3, \-\-highlight\-bars\f1[\f3=\f2num\f1]\f3
Specify how high the highlight bars are in lines.  If the \f2num\f1 is
not given, the default value 2 is used.  As a default, no highlight bars
are printed.
.TP 8
.B \-i \f2num\f3, \-\-indent=\f2num\f3
Indent every line \f2num\f1 characters.  The indentation can also be
specified in other units by appending an unit specifier after the
number.  The possible unit specifiers and the corresponding units are:
.RS 8
.TP 8
.B c
centimeters
.TP 8
.B i
inches
.TP 8
.B l
characters (default)
.TP 8
.B p
PostScript points
.RE
.TP 8
.B \-I \f2filter\f3, \-\-filter=\f2filter\f1
Read all input files through an input filter \f2filter\f1.  The input
filter can be a single command or a command pipeline.  The filter can
refer to the name of the input file with the escape `\f3%s\f1'.  The
name of the standard input can be changed with the option
`\f3\-\-filter\-stdin\f1'.

For example, the following command prints the file `foo.c' by using
only upper-case characters:

.B enscript \-\-filter="cat %s | tr 'a-z' 'A-Z'" foo.c

The following command highlights changes which are made to files since
the last checkout:

.B enscript \-\-filter="rcsdiff %s | diffpp %s" \-e *.c

To include the string "%s" to the filter command, you must write it as
"%%s".
.TP 8
.B \-j, \-\-borders
Print borders around columns.
.TP 8
.B \-J \f2title\f3
An alias for the option \f3\-t\f1, \f3\-\-title\f1.

Enable page prefeed.
.TP 8
.B \-K, \-\-no\-page\-prefeed
Disable page prefeed (default).
.TP 8
.B \-l, \-\-lineprinter
Emulate lineprinter.  This option is a shortcut for the options
\f3\-\-lines\-per\-page=66\f1, and \f3\-\-no\-header\f1.
.TP 8
.B \-L \f2num\f3, \-\-lines\-per\-page=\f2num\f3
Print only \f2num\f1 lines for each page.  As a default, the number of
lines per page is computed from the height of the page and from the
size of the font.
.TP 8
.B \-m, \-\-mail
Send a mail notification to user after the print job has been
completed.
.TP 8
.B \-M \f2name\f3, \-\-media=\f2name\f3
Select an output media \f2name\f1.  \f3Enscript\f1's default output
media is determined from libpaper and falls back to \f3@media@\f1.
.TP 8
.B \-n \f2num\f3, \-\-copies=\f2num\f3
Print \f2num\f1 copies of each page.
.TP 8
.B \-N \f2nl\f3, \-\-newline=\f2nl\f3
Select the \f2newline\f1 character.  The possible values for \f2nl\f1
are: \f3n\f1 (unix newline, 0xa hex) and \f3r\f1 (mac newline, 0xd hex).
.TP 8

enscript sends the output to the standard output \f3stdout\f1.
.TP 8
.B \-P \f2name\f3, \-\-printer=\f2name\f3
Spool the output to the printer \f2name\f1.
.TP 8

.TP 8
.B \-R, \-\-portrait
Print in the portrait mode (default).
.TP 8
.B \-s \f2num\f3, \-\-baselineskip=\f2num\f3
Specify the baseline skip in PostScript points.  The number \f2num\f1
can be given as a decimal number.  When \f3enscript\f1 moves from line
to line, the current point \f2y\f1 coordinate is moved (\f2font point
size + baselineskip\f1) points down.  The default baseline skip is 1.
.TP 8
.B \-S \f2key\f1[\f3:\f2value\f1]\f3, \-\-statusdict=\f2key\f1[\f3:\f2value\f1]\f3
Pass a statusdict definition to the generated PostScript output.  If
no value is given, the key \f2key\f1 is removed from the definitions.

The statusdict operators are implementation dependent; see the
printer's documentation for the details.

For example, the command

.B enscript \-Ssetpapertray:1 foo.txt

prints the file \f2foo.txt\f1 by using paper from the paper tray 1
(assuming that the printer supports paper tray selection).
.TP 8
.B \-t \f2title\f3, \-\-title=\f2title\f3
Set banner page's job title to \f2title\f1.  The option sets also the
name of the input file \f3stdin\f1.
.TP 8

text can be changed with the options \f3\-\-ul\-angle\f1,
\f3\-\-ul\-font\f1, \f3\-\-ul\-gray\f1, \f3\-\-ul\-position\f1, and
\f3\-\-ul\-style\f1.

If no \f2text\f1 is given, the underlay is not printed.  This can be used
to remove an underlay text that was specified with the
`\f3Underlay\f1' configuration file option.
.TP 8
.B \-U \f2num\f3, \-\-nup=\f2num\f3
Print \f2num\f1 logical pages on each output page (N\-up printing).

.SH FANCY HEADERS

Users can create their own fancy headers by creating a header
description file and placing it in a directory which is in
\f3enscript\f1's library path.  The name of the header file must be in
format: `\f2headername\f1.hdr'.  Header can be selected by giving
option: \f3\-\-fancy\-header=\f2headername\f1.

Header description file contains PostScript code that paints the
header.  Description file must provide procedure \f3do_header\f1 which
is called by \f3enscript\f1 at the beginning of every page.

Header description file contains two parts: comments and code.  Parts
are separated by a line containing text:

% \-\- code follows this line \-\-

.B Enscript
copies only the code part of description file to the generated
PostScript output.  The comments part can contain any data, it is not
copied.  If separator line is missing, no data is copied to output.

.B Enscript
defines following constants which can be used in header description
files:
.TP 16

where \f2width\f1 specifies the width of the column to which the
escape is printed.  For example, escape "$5%" will expand to something
like " 12".  If the width is negative, the value will be printed
left-justified.

For example, the `emacs.hdr' defines its date string with the

According to Adobe's Document Structuring Conventions (DSC), all
resources needed by a document must be listed in document's prolog.
Since user's can create their own headers, \f3enscript\f1 don't know
what resources those headers use.  That's why all headers must contain
a standard DSC comment that lists all needed resources.  For example,
used fonts can be listed with following comment:

%%DocumentNeededResources: font \f2fontname1\f1 \f2fontname2\f1

Comment can be continued to the next line with the standard
continuation comment:

%%+ font \f2fontname3\f1

.SH SPECIAL ESCAPES

\f3Enscript\f1 supports special escape sequences which can be used to
add some page formatting commands to ASCII documents.  As a default,
special escapes interpretation is off, so all ASCII files print out as
everyone expects.  Special escapes interpretation is activated by
giving option \f3\-e\f1, \f3\-\-escapes\f1 to \f3enscript\f1.

All special escapes start with the escape character.  The default
escape character is ^@ (octal 000); escape character can be changed
with option \f3\-e\f1, \f3\-\-escapes\f1.  Escape character is
followed by escape's name and optional options and arguments.

Currently \f3enscript\f1 supports following escapes:
.TP 8
.B bgcolor
change the text background color.  The syntax of the escape is:

^@bgcolor{\f2red\f1 \f2green\f1 \f2blue\f1}

where the color components \f2red\f1, \f2green\f1, and \f1blue\f1 are
given as decimal numbers between values 0 and 1.

.TP 8
.B bggray
change the text background color.  The syntax of the escape is:

^@bggray{\f2gray\f1}

where \f2gray\f1 is the new text background gray value.  The default
value is 1.0 (white).
.TP 8
.B color
change the text color.  The syntax of the escape is:

^@color{\f2red\f1 \f2green\f1 \f2blue\f1}

where color components \f2red\f1, \f2green\f1 and \f2blue\f1 are given
as decimal numbers between values 0 and 1.
.TP 8
.B comment
comment the rest of the line including the newline character.
Escape's syntax is:

^@comment \f2text\f1 \f2newline_character\f1
.TP 8
.B escape
change the escape character.  The syntax of the escape is:

^@escape{\f2code\f1}

where \f2code\f1 is the decimal code of the new escape character.
.TP 8
.B epsf
inline EPS file to the document.  The syntax of the escape is:

^@epsf[\f2options\f1]{\f2filename\f1}

where \f2options\f1 is an optional sequence of option characters and
values enclosed with brackets and \f2filename\f1 is the name of the
EPS file.

If \f2filename\f1 ends to the `|' character, then \f2filename\f1 is
assumed to name a command that prints EPS data to its standard output.
In this case, \f3enscript\f1 opens a pipe to the specified command
and reads EPS data from pipe.

Following options can be given for the \f3epsf\f1 escape:
.RS 8
.TP 8
.B c
print image centered
.TP 8
.B r
print image right justified
.TP 8
.B n

.TP 8
.B sy\f2num\f3
scale image in \f2y\f1 direction with factor \f2num\f1
.P
As a default, all dimensions are given in lines (vertical) and
characters (horizontal).  You can also specify other units by
appending an unit specifier after number.  Possible unit specifiers
and the corresponding units are:
.TP 8
.B c
centimeters
.TP 8
.B i
inches
.TP 8
.B l
lines or characters (default)
.TP 8
.B p
PostScript points
.P
For example to print an image one inch high, you can specify height by
following options: \f3h1i\f1 (1 inch), \f3h2.54c\f1 (2.54 cm),
\f3h72p\f1 (72 points).
.RE
.TP 8
.B font
select current font.  The syntax of the escape is:

^@font{\f2fontname\f1[:\f2encoding\f1]}

where \f2fontname\f1 is a standard font specification.  Special font
specification \f3default\f1 can be used to select the default body
font (\f3enscript\f1's default or the one specified by the command
line option \f3\-f\f1, \f3\-\-font\f1).

The optional argument \f2encoding\f1 specifies the encoding that
should be used for the new font.  Currently the encoding can only be
the \f3enscript\f1's global input encoding or \f3ps\f1.
.TP 8
.B ps
include raw PostScript code to the output.  The syntax of the escape
is:

^@ps{\f2code\f1}
.TP 8
.B shade
highlight regions of text by changing the text background color.
Escape's syntax is:

^@shade{\f2gray\f1}

where \f2gray\f1 is the new text background gray value.  The default
value is 1.0 (white) which disables highlighting.

.SH PAGE DEVICE OPTIONS

Page device is a PostScript level 2 feature that offers an uniform
interface to control printer's output device.  \f3Enscript\f1
protects all page device options inside an if block so they have no
effect in level 1 interpreters.  Although all level 2 interpreters
support page device, they do not have to support all page device
options.  For example some printers can print in duplex mode and some
can not.  Refer to the documentation of your printer for supported
options.

Here are some usable page device options which can be selected with
the \f3\-D\f1, \f3\-\-setpagedevice\f1 option.  For a complete listing,
see \f2PostScript Language Reference Manual\f1: section 4.11 Device
Setup.

.SH ENVIRONMENT VARIABLES

The environment variable \f3ENSCRIPT\f1 can be used to pass default
options for \f3enscript\f1.  For example, to select the default body
font to be Times\-Roman 7pt, set the following value to the
\f3ENSCRIPT\f1 environment variable:
.TP 8
.B \-fTimes\-Roman7
.P

The value of the \f3ENSCRIPT\f1 variable is processed before the
command line options, so command line options can be used to overwrite
these defaults.

Variable \f3ENSCRIPT_LIBRARY\f1 specifies the \f3enscript\f1's
library directory.  It can be used to overwrite the build-in default
`@DATADIR@/enscript'.

.SH RETURN VALUE

\f3Enscript\f1 returns value 1 to the shell if any errors were
encountered or 0 otherwise.  If the option
\f3\-\-extended\-return\-values\f1 was specified, the return value is
constructed from the following flags:
.TP 8
.B 0
no errors or warnings
.TP 8
.B 2
some lines were truncated or wrapped
.TP 8
.B 4
some characters were missing from the used fonts
.TP 8
.B 8
some characters were unprintable
