SYNOPSIS

tnylpo-convert [-aeiz] [-f <config-file>] [ (-u (<fn> | -) | -c <fn>) [ (-u (<fn> | -) | -c <fn>) ] ]

tnylpo-convert -h

DESCRIPTION

The difference between the Unix text file format and CP/M text files is threefold:

—

Unix uses a single <lf> (0x0a) character as line end marker, while CP/M uses the sequence <cr> <lf> (0x0d 0x0a).

—

CP/M uses the first <sub> (0x1a) character in the file as end of file marker, except if the logical end of the text file coincides with a 128 byte record boundary

—

CP/M uses 8-bit (or 7-bit) characters, while most recent operating systems use wide or multibyte character sets.

tnylpo-convert shares its configuration files with tnylpo(1), but uses only the options for the character set definitions ([alt] char, [alt] charset, and unprintable), on which it bases its character translation. Both the configuration file syntax and the way tnylpo-convert finds its configuration are described in the man page of tnylpo(1).

OPTIONS

-a

use the alternate character set from the configuration file for character translation

-c <cpm-textfile>

use the text file <cpm-textfile> in CP/M format as source or target of the conversion

-e

treat unconvertible characters in the source file as an error

-f <config-file>

tell tnylpo-convert explicitly which configuration file to use

-h

ask tnylpo-convert to show a short command line synopsis (-h cannot be used in combination with any other command line option)

-i

ignore all unconvertible characters by silently dropping them

-u <textfile>

use the text file <textfile> in host system format as source or target of the conversion; if - is given instead of <textfile>, stdin is read resp. stdout is written

-z

always append a <sub> (0x1a) character as an end of file marker to CP/M text files, even if they end on a record boundary

The options -e and -i are mutually exclusive; if neither is given, tnylpo-convert will drop unconvertible characters, but issue a warning.

tnylpo-convert takes no positional arguments. The -c and -u options may be given at most twice; the first occurrence defines the source file, the second occurrence the target file of the conversion. If the target file or both source and target files are missing, -u - is used instead. The same file name may be given both as source and as target, since tnylpo-convert uses a temporary file for output, which is renamed to the target file name on successful completion (this is not done if stdout is used for output).

EXIT STATUS

FILES

EXAMPLES

converts the contents of the CP/M text file hugo.txt to the format and character set of the host operating system and prints them on stdout. Character set information is taken from the configuration file myconf.conf, and any unconvertible characters in hugo.txt will cause the conversion to fail.

tnylpo-convert -u test.pas -c test.pas -z

converts the Unix text file test.pas to CP/M format; the default configuration file (if found) is used for character set information. The resulting file is always terminated with at least one <sub> (0x1a) character.
