kbdpipe(1)kbdpipe(1)NAMEkbdpipe - use the kbd module in a pipeline
SYNOPSISkbdpipe-t table [-f tablefile] [-F] [-o outfile] [infile(s)]
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 mostly useful in code set
conversion applications. If an output file is given, then all infiles
are piped to the given 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 given 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 filename 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.

NOTES
Because kbdpipe uses kbdload(1) to load tables, it cannot resolve link
references. Therefore, if a composite table is to be used, the relevant
portions must either be already loaded and public, or be contained in the
file indicated (via the -f option) on the command line; in this 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; hence, there is no
real need to use the kbdpipe command. kbdpipe may not be supported in
future releases.
