DESCRIPTION
Enscript converts text files to PostScript or to other output lan-
guages. Enscript can spool the generated output directly to a speci-
fied 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 mod-
ification 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 data and page numbers:
enscript --header='$n %W Page $% of $=' *.c
The header string can also contain left, center and right jus-
tified fields. The fields are separated by the '|' character:
enscript --header='$n|%W|Page $% of $=' *.c
now the file name is printed left justified, the date is cen-
tered to the header and the page numbers are printed right jus-
tified.
-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 out-
put. 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 dependant 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 edu-
cated 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/gnu/share/enscript/st/*.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 exam-
ple, "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 CON-
FIGURATION 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 fil-
ter 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 Letter.
-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 out-
put. If no value is given, the key key is removed from the
definitions.
The statusdict operators are implementation dependant; 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.

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.
--color[=bool]
Use colors in the highlighting outputs.
--download-font=fontname
Include the font description file (.pfa or .pfb file) of the
font fontname to the generated output.
--extended-return-values
Enable extended return values. As a default, enscript returns
1 on error and 0 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-col-
umns.
--help Print a short help message and exit.
--help-highlight

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 configura-
tion file (/usr/gnu/etc/enscriptsite.cfg) and system's global configu-
ration file (/usr/gnu/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: bool
Specify if the Control-D (^D) character should be appended to
the end of the output. The default value is false (0).
Clean7Bit: bool
Specify how characters greater than 127 are printed. The val-
uee true (1) generates 7-bit clean code by escaping all charac-
ters 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
Select the default fancy header. The default header is used
when the option -G is 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)
stdout send output to stdout
DownloadFont: fontname
Include the font description file of the font fontname to the
generated output.
EscapeChar: num
Specify the escape character for the special escapes. The
default value is 0.
FormFeedType: type
Specify what to do when a formfeed character is encountered
from the input. The possible values for type are:
column move to the beginning of the next column (default)
page move to the beginning of the next page
GeneratePageSize: bool
Specify whether the PageSize page device setting is generated
to the PostScript output. The default value is true (1).
HighlightBarGray: gray
Specify the gray level which is used to print the highlight
bars.
HighlightBars: num
Specify how high the highlight bars are in lines. The default
value is 0 which means that no highlight bars are printed.
LibraryPath: path
Specifies the enscript's library path that is used to lookup
various resources. The default path is:
`/usr/gnu/share/enscript:home/.enscript'. Where the home is
the user's home directory.
MarkWrappedLines: style
Mark wraped lines in the output with the style style. The pos-
sible values for the format are the same which can be given for
the --mark-wrapped-lines option.
Media: name width height llx lly urx ury
Add a new output media with the name name. The physical dimen-
sions of the media are width and height. The bounding box of
the Media is specified by the points (llx, lly) and (urx, ury).
Enscript prints all graphics inside the bounding box of the
media.
User can select this media with option -M name.
NoJobHeaderSwitch: switch
Specify the spooler option to suppress the print job header
page. This option is passed to the printer spooler when the
enscript's option -h, --no-job-header is selected.

Specify how the non-printable characters are printed. The pos-
sible values for format are the same which can be given for the
--non-printable-format option.
OutputFirstLine: line
Set the PostScript output's first line to line. The default
value is PS-Adobe-3.0. Since some printers do not like DSC
levels greater than 2.0, this option can be used to change the
output first line to something more suitable like %!PS-
Adobe-2.0 or %!.
PageLabelFormat: format
Set the page label format to format. The possible values for
format are the same which can be given for the
--page-label-format option.
PagePrefeed: bool
Enable / disable page prefeed. The default value is false (0).
PostScriptLevel: level
Set the PostScript language level, that enscript uses for its
output, to level. The possible values for level are the same
which can be given for the --ps-level option.
Printer: name
Names the printer to which the output is spooled.
QueueParam: name
The spooler command switch to select the printer queue, e.g. -P
in lpr -Pps. This option can also be used to pass other flags
to the spooler command. These options must be given before the
queue switch.

UnderlayStyle: style
Set the underlay text's style to style.
FANCY HEADERS
Users can create their own fancy headers by creating a header descrip-
tion 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 head-
ers 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 syn-
tax:
%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 continua-
tion comment:

Enscript supports special escape sequences which can be used to add
some page formatting commands to ASCII documents. As a default, spe-
cial escapes interpretation is off, so all ASCII files print out as
everyone expects. Special escapes interpretation is activated by giv-
ing 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 (abso-
lute position)
ynum move image's top left y coordinate num lines from cur-
rent 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 speci-
fiers 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 docu-
mentation 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 con-
figuration. If default actions have been changed from the configura-
tion 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 (land-
scape).
enscript -DDuplex:true foo.txt
Print file in duplex (two side) mode (printer dependant).
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/gnu/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
