SYNOPSIS
digits] seq] just] mode] order] margin] width] ck] [file ...]
DESCRIPTION
formats for printing data written in languages with a right-to-left
orientation. It is designed to be used with the and the commands (see
pr(1) and lp(1)).
reads the concatenation of input files (or standard input if none are
given) and produces on standard output a right-to-left formatted ver‐
sion of its input. If appears as an input file name, reads standard
input at that point. Use to delimit the end of options.
formats input files for all languages that are read from right to left.
For languages that have a left-to-right orientation, the command merely
copies input files to standard output.
Options
recognizes the following options:
Justify data for all languages,
including those having a left-to-right text orienta‐
tion. By default only right-to-left language data
is justified. For all other languages, input files
are directly copied to standard output.
Select enhanced printer shapes for some Arabic characters.
With this option, two-character combinations of laam
and alif are replaced by a single character.
Triggers ISO 8859-6 interpretation of the data.
Processes digits for output as hindi, western, or both.
digits can be or both.
Use seq as the escape sequence to select the primary
character set. This escape sequence is used by lan‐
guages that have too many characters to be accommo‐
dated by ASCII in a single 256-character set. In
these cases, the seq escape sequence can be used to
select the non-ASCII character set. The escape
character itself (0x1b) is not given on the command
line. Hewlett-Packard escape sequences are used by
default.
If just is left justify print lines. If just is right-
justify print lines starting from the (designated or
default) print width column. The default is right
justification.
Replace leading spaces with alternative spaces.
Some right-to-left character sets have a non-ASCII
or alternative space. This option can be useful
when filtering output (see pr(1)). With right jus‐
tification, the option causes line numbers to be
placed immediately to the right of the tab charac‐
ter. Without the option, right justification causes
line numbers to be placed at the print-width column.
By default, leading spaces are not replaced by
alternative spaces.
Indicate mode of any file to be formatted. Mode refers to
the text orientation of the file when it was cre‐
ated. If mode is assume Latin mode. If mode is
assume non-Latin mode. By default, mode information
is obtained from the environment variable.
Do not terminate lines containing printable characters with a
new-line.
By default, print lines are terminated by new-lines.
Indicate data
order of any file to be formatted. The text orien‐
tation of a file can affect the way its data is
arranged. If order is assume keyboard order. If
order is assume screen order. By default, order
information is obtained from the environment vari‐
able.
Truncate print lines
that do not fit the designated or default line
length. Print lines are folded (that is, wrapped to
next line) by default.
Expand input tabs to column positions
k+1, 2*k+1, 3*k+1, etc. Tab characters in the input
are expanded to the appropriate number of spaces.
If k is 0 or is omitted, default tab settings at
every eighth position is assumed. If cd (any non-
digit character) is given, it is treated as the
input tab character. The default for c is the tab
character. always expands input tabs. This option
provides a way to change the tab character and set‐
ting. If this option is specified, at least one of
the parameters c or k must be given.
Designate a number as the print
margin. The print margin is the column where trun‐
cation or folding takes place. The print margin
determines how many characters appear on a single
line and can never exceed the print width. The
print margin is relative to the justification. If
the print margin is 80, folding or truncation occurs
at column 80 starting from the right during a right
justification. Similarly, folding or truncation
occurs at column 80 starting from the left during a
left justification. By default, the print margin is
set to column 80.
Designates a number as the print
width. The print width is the maximum number of
columns in the print line. Print width determines
the start of text during a right justification. The
larger the print width, the further to the right the
text will start. By default, an 80-column print
width is used.
EXTERNAL INFLUENCES
Environment Variables
The environment variable determines the mode and order of the file.
The syntax of is [mode][_order]. mode describes the mode of a file
where represents Latin mode and represents non-Latin mode. Non-Latin
mode is assumed for values other than and order describes the data
order of a file where is keyboard and is screen. Keyboard order is
assumed for values other than and Mode and order information in can be
overridden from the command line.
The environment variable determines the direction of a language (left-
to-right or right-to-left) and whether context analysis of characters
is necessary.
The environment variable determines whether a language has alternative
numbers.
The environment variable determines the language in which messages are
displayed.
International Code Set Support
Single-byte character code sets are supported.
EXAMPLES
Right justify on a 132-column printer with a print margin at column 80
(the default):
Right justify output of with line numbers on a 132-column printer with
a print margin at column 132:
WARNINGS
If with line numbers option) is piped to the separator character must
be a tab (0x09).
It is the user's responsibility to ensure that the environment variable
accurately reflects the status of the file.
Mode and justification must be consistent. Only non-Latin-mode files
can be right justified in a meaningful way. Similarly, only Latin-mode
files can be safely left justified. If mode and justification do not
match, the results are undefined.
If present, alternative numbers always have a left-to-right orienta‐
tion.
The command is HP proprietary, not portable to other vendors' systems,
and will not be provided in future HP-UX releases.
