setting. If this option is specified, at least one of the parameters c or k must be given.
-r margin Designate a number as the print margin. The print margin is the column where trunca-
tion 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 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
LANGOPTS environment variable determines the mode and order of the file. The syntax of
LAN-
GOPTS
is [mode ][_order ]. mode describes the mode of a file where
l represents Latin mode and n
represents non-Latin mode. Non-Latin mode is assumed for values other than l and n. order describes
the data order of a file where
k is keyboard and s is screen. Keyboard order is assumed for values other
than k and s. Mode and order information in LANGOPTS can be overridden from the command line.
The LC_ALL environment variable determines the direction of a language (left-to-right or right-to-left) and
whether context analysis of characters is necessary.
The LC_NUMERIC environment variable determines whether a language has alternative numbers.
The LANG environment variable determines the language in which messages are displayed.
International Code Set Support
Single-byte character code sets are supported.
EXAMPLES
Right justify file1 on a 132-column printer with a print margin at column 80 (the default):
nljust -w 132 file1 | lp
Right justify pr output of file2 with line numbers on a 132-column printer with a print margin at
column 132:
pr -n file2 | nljust -w 132 -r 132 | lp
WARNINGS
If pr with line numbers (-n option) is piped to nljust, the separator character must be a tab (0x09).
It is the user’s responsibility to ensure that the
LANGOPTS 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 orientation.
The
nljust command is HP proprietary, not portable to other vendors’ systems, and will not be provided
in future HP-UX releases.
