written in languages with a right-to-left orientation.
It is designed to be used with the

For languages that have a left-to-right orientation,
the command merely copies input files to standard output.
recognizes the following options:
Justify data for all languages,
including those having a left-to-right text orientation.
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.
- -d digits
Processes digits for output as hindi, western, or both.
- -e seq
as the escape sequence to select the primary character set.
This escape sequence is used by languages
that have too many characters to be accommodated by
in a single 256-character set.
In these cases, the
escape sequence can be used to select the non-ASCII

Hewlett-Packard escape sequences are used by default.
- -j just
left justify print lines.
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

By default, leading spaces are not replaced by alternative spaces.

Mode refers to the text orientation of the file when it was created.

By default, print lines are terminated by new-lines.

This option provides a way to change the tab character and setting.
If this option is specified, at least one of the parameters
must be given.
- -r margin
Designate a number as the print
The print margin is the column
where truncation 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.
- -w width
Designates a number as the print
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.

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.
alternative numbers always have a left-to-right orientation.
