DESCRIPTION


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

OPTIONS


-# num Print num copies of each page.

-1, -2, -3, -4, -5, -6, -7, -8, -9, --columns=num
Specify how many columns each page have. With the long option --columns=num you
can specify more than 9 columns per page.

-a pages, --pages=pages
Specify which pages are printed. The page specification pages can be given in the
following formats:

begin-end
print pages from begin to end

-end print pages from 0 to end

begin- print pages from begin to end

page print page page

odd print odd pages

even print even pages

-A align, --file-align=align
Align separate input files to even align page count. This option is useful in
two-side and 2-up printings (--file-align=2).

-b header, --header=header
Use the text header 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 header can contain the same formatting escapes which can be
specified for the %Format directives in the user defined fancy headers. For
example, the following option prints the file name, current date and page numbers:

enscript --header='$n %W Page $% of $=' *.c

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

enscript --header='$n|%W|Page $% of $=' *.c

now the file name is printed left justified, the date is centered to the header
and the page numbers are printed right justified.

-B, --no-header
Do not print page headers.

-c, --truncate-lines
Cut lines that are too long for the page. As a default, enscript wraps long lines
to the next line so no information is lost.

You can also use the --slice option which slices long lines to separate pages.

-C[start_line], --line-numbers[=start_line]
Precede each line with its line number. The optional argument start_line
specifies the number of the first line in the input. The number of the first line
defaults to 1.

-d name Spool output to the printer name.

-D key[:value], --setpagedevice=key[:value]
Pass a page device definition to the generated PostScript output. If no value is
given, the key key is removed from the definitions.

For example, the command

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 PAGE DEVICE OPTIONS for the details.

-e[char], --escapes[=char]
Enable special escapes interpretation (see section SPECIAL ESCAPES). If the
argument char is given, it changes the escape character to char. The default
escape character is 0.

-E[lang], --highlight[=lang]
Highlight source code by creating a special input filter with the states program.
The optional argument lang specifies the language to highlight. As a default the
states makes an educated guess.

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

enscript --help-highlight

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

Note! You can not use your own input filters with this option.

-f name, --font=name
Select a font that is used for the body text. The default body font is Courier10,
unless multicolumn landscape printing mode is selected, in which case the default
font is Courier7.

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

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

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

You can also give the font sizes as decimal numbers. For example,
"Times-Roman10.2" selects a 10.2pt "Times-Roman" font.

-F name, --header-font=name
Select a font for the header texts.

-g, --print-anyway
Print a file even if it contains binary data. The option is implemented only for
compatibility purposes. Enscript prints binary files anyway regardless of the
option.

-G, --fancy-header[=name]
Print a fancy page header name to the top of each page. The option -G specifies
the default fancy header. See section CONFIGURATION FILES to see how the default
fancy header can be changed.

-h, --no-job-header
Suppress printing of the job header page.

-H[num], --highlight-bars[=num]
Specify how high the highlight bars are in lines. If the num is not given, the
default value 2 is used. As a default, no highlight bars are printed.

-i num, --indent=num
Indent every line num 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:

c centimeters

i inches

l characters (default)

p PostScript points

-I filter, --filter=filter
Read all input files through an input filter filter. 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 `%s'. The name of the standard input can be changed
with the option `--filter-stdin'.

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

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:

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

To include the string "%s" to the filter command, you must write it as "%%s".

-j, --borders
Print borders around columns.

-J title
An alias for the option -t, --title.

-k, --page-prefeed
Enable page prefeed.

-K, --no-page-prefeed
Disable page prefeed (default).

-l, --lineprinter
Emulate lineprinter. This option is a shortcut for the options
--lines-per-page=66, and --no-header.

-L num, --lines-per-page=num
Print only num 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.

-m, --mail
Send a mail notification to user after the print job has been completed.

-M name, --media=name
Select an output media name. Enscript's default output media is determined from
libpaper and falls back to A4.

-n num, --copies=num
Print num copies of each page.

-N nl, --newline=nl
Select the newline character. The possible values for nl are: n (unix newline,
0xa hex) and r (mac newline, 0xd hex).

-o file An alias for the option -p, --output.

-O, --missing-characters
Print a listing of character codes which couldn't be printed.

-p file, --output=file
Leave the output to file file. If the file is `-', enscript sends the output to
the standard output stdout.

-P name, --printer=name
Spool the output to the printer name.

-q, --quiet, --silent
Make enscript really quiet. Only fatal error messages are printed to stderr.

-r, --landscape
Print in the landscape mode; rotate page 90 degrees.

-R, --portrait
Print in the portrait mode (default).

-s num, --baselineskip=num
Specify the baseline skip in PostScript points. The number num can be given as a
decimal number. When enscript moves from line to line, the current point y
coordinate is moved (font point size + baselineskip) points down. The default
baseline skip is 1.

-S key[:value], --statusdict=key[:value]
Pass a statusdict definition to the generated PostScript output. If no value is
given, the key key is removed from the definitions.

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

For example, the command

enscript -Ssetpapertray:1 foo.txt

prints the file foo.txt by using paper from the paper tray 1 (assuming that the
printer supports paper tray selection).

-t title, --title=title
Set banner page's job title to title. The option sets also the name of the input
file stdin.

-T num, --tabsize=num
Set the tabulator size to num characters. The default is 8.

-u[text], --underlay[=text]
Print the string text under every page. The properties of the text can be changed
with the options --ul-angle, --ul-font, --ul-gray, --ul-position, and --ul-style.

If no text is given, the underlay is not printed. This can be used to remove an
underlay text that was specified with the `Underlay' configuration file option.

-U num, --nup=num
Print num logical pages on each output page (N-up printing). The values num must
be a power of 2.

-v, --verbose[=level]
Tell what enscript is doing.

-V, --version
Print enscript version information and exit.

-w [lang], --language[=lang]
Generate output for the language lang. The possible values for lang are:

that enscript can be used as a lp filter.

The PostScript files are recognized by looking up the `%!' magic cookie from the
beginning of the file. Note! Enscript recognized also the Windoze damaged `^D%!'
cookie.

The PCL files are recognized by looking up the `^[E' or `^[%' magic cookies from
the beginning of the file.

otherwise. The extended return values give more details about the printing
operation. See the section RETURN VALUE for the details.

--filter-stdin=name
Specify how the stdin is shown to the input filter. The default value is an empty
string ("") but some programs require that the stdin is called something else,
usually "-".

--footer=footer
Use the text footer as a page footer. Otherwise the option works like the
--header option

--h-column-height=height
Set the horizontal column height to be height PostScript points. The option sets
the formfeed type to horizontal-columns.

CONFIGURATION FILES


Enscript reads configuration information from the following sources (in this order):
command line options, environment variable ENSCRIPT, user's personal configuration file
($HOME/.enscriptrc), site configuration file (/etc/enscriptsite.cfg) and system's global
configuration file (/etc/enscript.cfg).

The configuration files have the following format:

Empty lines and lines starting with `#' are comments.

All other lines are option lines and have format:

option [arguments ...].

The following options can be specified:

AcceptCompositeCharacters: bool
Specify whether PostScript font's composite characters are accepted as printable
or if they should be considered as non-existent. The default value is false (0).

AFMPath: path
Specifies the search path for the AFM files.

AppendCtrlD: int

output. A value of 1 will append ^D followed by a newline, a value of 2 will omit
the trailing newline. The default value is 0 for no ^D.

Clean7Bit: bool
Specify how characters greater than 127 are printed. The valuee true (1)
generates 7-bit clean code by escaping all characters greater than 127 to the
backslash-octal notation (default). The value false (0) generates 8-bit
PostScript code leaving all characters untouched.

DefaultEncoding: name
Select the default input encoding. The encoding name name can be one of the
values of the option -X, --encoding.

DefaultFancyHeader: name

specified or the option --fancy-header is given without an argument. The
system-wide default is `enscript'.

DefaultMedia: name
Select the default output media.

DefaultOutputMethod: method
Select the default target to which the generated output is sent. The possible
values for the method are:

printer send output to printer (default)

FANCY HEADERS


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

Header description file contains PostScript code that paints the header. Description file
must provide procedure do_header which is called by enscript 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 --

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.

Enscript defines following constants which can be used in header description files:

d_page_w page width

d_page_h page height

d_header_x header lower left x coordinate

d_header_y header lower left y coordinate

d_header_w header width

d_header_h header height

d_footer_x footer lower left x coordinate

d_footer_y footer lower left y coordinate

d_footer_w footer width

d_footer_h footer height

d_output_w width of the text output area

d_output_h height of the text output area

user_header_p predicate which tells if user has defined his/her own header string:
true/false

user_header_left_str
if user_header_p is true, this is the left field of the user supplied
header string.

user_header_center_str
if user_header_p is true, this is the center field of the user supplied
header string

user_header_right_str
if user_header_p is true, this is the right field of the user supplied
header string

user_footer_p predicate which tells if user has defined his/her own footer string:
true/false

user_footer_left_str
if user_footer_p is true, this is the left field of the user supplied
footer string.

user_footer_center_str
if user_footer_p is true, this is the center field of the user supplied
footer string

user_footer_right_str
if user_footer_p is true, this is the right field of the user supplied
footer string

HF standard header font (from -F, --header-font option). This can be
selected simply by invoking command: `HF setfont'.

pagenum the number of the current page

fname the full name of the printed file (/foo/bar.c)

fdir the directory part of the file name (/foo)

ftail file name without the directory part (bar.c)

gs_languagelevel
PostScript interpreter's language level (currently 1 or 2)

You can also use the following special comments to customize your headers and to specify
some extra options. Special comments are like DSC comments but they start with a single
`%' character; special comments start from the beginning of the line and they have the
following syntax:

%commentname: options

Currently enscript support the following special comments:

%Format: name format
Define a new string constant name according to the format string format. Format
string start from the first non-space character and it ends to the end of the
line. Format string can contain general `%' escapes and input file related `$'
escapes. Currently following escapes are supported:

%% character `%'

$$ character `$'

$% current page number

$= number of pages in the current file

$p number of pages processed so far

$(VAR) value of the environment variable VAR.

%c trailing component of the current working directory

%C ($C) current time (file modification time) in `hh:mm:ss' format

%d current working directory

%D ($D) current date (file modification date) in `yy-mm-dd' format

%D{string} ($D{string})
format string string with the strftime(3) function. `%D{}' refers to the
current date and `$D{}' to the input file's last modification date.

%E ($E) current date (file modification date) in `yy/mm/dd' format

%F ($F) current date (file modification date) in `dd.mm.yyyy' format

%H document title

$L number of lines in the current input file. This is valid only for the toc
entries, it can't be used in header strings.

%m the hostname up to the first `.' character

%M the full hostname

%n the user login name

$n input file name without the directory part

%N the user's pw_gecos field up to the first `,' character

$N the full input file name

%t ($t) current time (file modification time) in 12-hour am/pm format

%T ($T) current time (file modification time) in 24-hour format `hh:mm'

%* ($*) current time (file modification time) in 24-hour format with seconds
`hh:mm:ss'

$v the sequence number of the current input file

$V the sequence number of the current input file in the `Table of Contents'
format: if the --toc option is given, escape expands to `num-'; if the
--toc is not given, escape expands to an empty string.

%W ($W) current date (file modification date) in `mm/dd/yy' format

All format directives except `$=' can also be given in format

escape width directive

where width 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 following format
comment:

%Format: eurdatestr %E

which expands to:

/eurdatestr (96/01/08) def

%HeaderHeight: height
Allocate height points space for the page header. The default header height is 36
points.

%FooterHeight: height
Allocate height points space for the page footer. The default footer height is 0
points.

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,
enscript 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 fontname1 fontname2

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

%%+ font fontname3

SPECIAL ESCAPES


Enscript 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 -e, --escapes to enscript.

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

Currently enscript supports following escapes:

bgcolor change the text background color. The syntax of the escape is:

^@bgcolor{red green blue}

where the color components red, green, and blue are given as decimal numbers
between values 0 and 1.

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

^@bggray{gray}

where gray is the new text background gray value. The default value is 1.0
(white).

color change the text color. The syntax of the escape is:

^@color{red green blue}

where color components red, green and blue are given as decimal numbers between
values 0 and 1.

comment comment the rest of the line including the newline character. Escape's syntax is:

^@comment text newline_character

escape change the escape character. The syntax of the escape is:

^@escape{code}

where code is the decimal code of the new escape character.

epsf inline EPS file to the document. The syntax of the escape is:

^@epsf[options]{filename}

where options is an optional sequence of option characters and values enclosed
with brackets and filename is the name of the EPS file.

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

Following options can be given for the epsf escape:

c print image centered

r print image right justified

n do not update current point. Following output is printed to that position
where the current point was just before the epsf escape

nx do not update current point x coordinate

ny do not update current point y coordinate

xnum move image's top left x coordinate num characters from current point x
coordinate (relative position)

xnuma set image's top left x coordinate to column num (absolute position)

ynum move image's top left y coordinate num lines from current line (relative
position)

ynuma set image's top left y coordinate to line num (absolute position)

hnum set image's height to num lines

snum scale image with factor num

sxnum scale image in x direction with factor num

synum scale image in y direction with factor num

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:

c centimeters

i inches

l lines or characters (default)

p PostScript points

For example to print an image one inch high, you can specify height by following
options: h1i (1 inch), h2.54c (2.54 cm), h72p (72 points).

font select current font. The syntax of the escape is:

^@font{fontname[:encoding]}

where fontname is a standard font specification. Special font specification
default can be used to select the default body font (enscript's default or the one
specified by the command line option -f, --font).

The optional argument encoding specifies the encoding that should be used for the
new font. Currently the encoding can only be the enscript's global input encoding
or ps.

ps include raw PostScript code to the output. The syntax of the escape is:

^@ps{code}

shade highlight regions of text by changing the text background color. Escape's syntax
is:

^@shade{gray}

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

PAGE DEVICE OPTIONS


Page device is a PostScript level 2 feature that offers an uniform interface to control
printer's output device. Enscript 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 -D,
--setpagedevice option. For a complete listing, see PostScript Language Reference Manual:
section 4.11 Device Setup.

Collate boolean
how output is organized when printing multiple copies

Duplex boolean
duplex (two side) printing

ManualFeed boolean
manual feed paper tray

OutputFaceUp boolean
print output `face up' or `face down'

Tumble boolean
how opposite sides are positioned in duplex printing

PRINTING EXAMPLES


Following printing examples assume that enscript uses the default configuration. If
default actions have been changed from the configuration files, some examples will behave
differently.

enscript foo.txt
Print file foo.txt to the default printer.

enscript -Possu foo.txt
Print file foo.txt to printer ossu.

enscript -pfoo.ps foo.txt
Print file foo.txt, but leave PostScript output to file foo.ps.

enscript -2 foo.txt
Print file foo.txt to two columns.

enscript -2r foo.txt
Print file to two columns and rotate output 90 degrees (landscape).

enscript -DDuplex:true foo.txt
Print file in duplex (two side) mode (printer dependent).

enscript -G2rE -U2 foo.c
My default code printing command: gaudy header, two columns, landscape, code
highlighting, 2-up printing.

enscript -E --color -whtml --toc -pfoo.html *.h *.c
A nice HTML report of your project's C source files.

ENVIRONMENT VARIABLES


The environment variable ENSCRIPT can be used to pass default options for enscript. For
example, to select the default body font to be Times-Roman 7pt, set the following value to
the ENSCRIPT environment variable:

-fTimes-Roman7

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

Variable ENSCRIPT_LIBRARY specifies the enscript's library directory. It can be used to
overwrite the build-in default `/usr/share/enscript'.

RETURN VALUE


Enscript returns value 1 to the shell if any errors were encountered or 0 otherwise. If
the option --extended-return-values was specified, the return value is constructed from
the following flags:

0 no errors or warnings

2 some lines were truncated or wrapped

4 some characters were missing from the used fonts

8 some characters were unprintable
