NAME
forder - convert file data order
SYNOPSIS
forder [-a][-l][
-n][file ... ]
DESCRIPTION
The text orientation (mode) of a file can be right-to-left (non-Latin) or left-to-right (Latin). This text
orientation can affect the way data is arranged in the file. The data arrangements that result are called
screen order and keyboard order.
forder converts the order of characters in the file from screen order
to keyboard order or vice versa.
forder reads the concatenation of input files (or standard input if none are given) and produces on stan-
dard output a converted version of its input. If
- appears as an input file name, forder reads stan-
dard input at that point (use
--
to delimit the end of options in such instances).
forder converts input files for all languages that are read from right-to-left. Unless the
-a option is
used, the command merely copies input files to standard output for languages that are read from left-to-
right.
Options
forder recognizes the following options:
-a Convert file data order for languages read from left-to-right.
-l Identify the file as having been created in Latin mode.
-n Identify the file as having been created in non-Latin mode.
EXTERNAL INFLUENCES
Environment Variables
The
LANGOPTS environment variable determines the mode and order of the file. The syntax of
LAN-
GOPTS
is:
[ mode ][_order ]
where mode describes the mode of a file:
l represents Latin mode, and n represents non-Latin mode.
Non-Latin mode is assumed for values other than l and n. The order describes the data order of a file:
k is keyboard, and s is screen. Keyboard order is assumed for values other than k
and s. Mode infor-
mation 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).
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
The following command begins with file1, which exists in screen order, converts it to keyboard order,
sorts the keyboard-ordered output, converts it back to screen order, and redirects the output to file2.
Note that
-n is given to inform forder that file1 was created in non-Latin mode.
forder -n file1 | sort | forder -n > file2
WARNINGS
It is the user’s responsibility to ensure that the LANGOPTS environment variable accurately reflects the
status of the file.
If present, alternative numbers always have a left-to-right orientation.
The
forder command is HP proprietary, not portable to other vendors’ systems, and will not be pro-
vided in future HP-UX releases.
