NAME
kbdpipe - use the kbd module in a pipeline
SYNOPSIS
kbdpipe -t table [-f tablefile] [-F] [-o outfile] [infile . . . ]
DESCRIPTION
The kbdpipe command allows the use of kbd tables as pipeline
elements between user programs. [See kbdcomp(1M) and kbd(7)
for descriptions of the module and its capabilities.] kbdpipe
is useful in code set conversion applications. If an output
file is specified, then all infiles are piped to that output
file. With no arguments other than -t, standard input is
converted and sent to standard output.
The required option argument -t identifies the table to be
used for conversion. If the table has already been loaded as
a shared table [see kbdload(1M)] it is attached. If, however,
the table has not been loaded, an attempt is made to load it.
If the specified table name is not an absolute pathname then
the name of the system mapping library is prepended to the
argument, and an attempt is made to load the table from the
resulting pathname (that is, it becomes an argument to the
loader, kbdload). Assuming the table can be loaded, it is
attached.
The argument to -f defines the file from which the table will
be loaded, overriding the default action described above. The
file is loaded (in its entirety), and the named table
attached. This option should be used if the default action
would fail.
The output file specified by -o must not already exist (a
safety feature). The option -F may be used to override the
check for existence of the output file; in this case, any
existing outfile will be truncated before being written.
EXAMPLES
The following example converts two input files into relative
nonsense by mapping ASCII into Dvorak keyboard equivalents
using the Dvorak table. The table is assumed to reside in the
file /usr/lib/kbd/Dvorak. The existing output file is
overwritten:
kbdpipe -F -t Dvorak -o iapxai.vj file1 file2

The following example loads the Dvorak table from a different
file, then converts standard input to standard output. The
Dvorak table (assumed to be non-resident) is explicitly loaded
from an absolute path beginning at the user's home directory:
kbdpipe -t Dvorak -f $HOME/tables/Dvorak.tab
FILES
/usr/lib/kbd directory containing system standard table
files.

NOTICES
Because kbdpipe uses kbdload(1M) to load tables, it cannot
resolve link references. Therefore, if a composite table is
used, the relevant portions must either be already loaded and
public, or be contained in the file used (via the -f option)
on the command line. In the latter case, the composite
elements must be loaded earlier than the link entry.
Users may use kbd tables in programs at user level by opening
a pipe, pushing the module, and setting via related commands.
Therefore, there is no need to use the kbdpipe command.
kbdpipe may not be supported in future releases.
