GENCAT(1) General Commands Manual GENCAT(1)
gencat – NLS catalog compiler
gencat output-file input-files...
The gencat utility merges the text NLS input files input-files... into a
formatted message catalog file output-file. The file output-file will be
created if it does not already exist. If output-file does exist, its
messages will be included in the new output-file. If set and message
numbers collide, the new message text defined in input-files... will
replace the old message text currently contained in output-file.
The format of a message text source file is defined below. Note that the
fields of a message text source line are separated by a single space
character: any other space characters are considered to be part of the
$set n comment
This line specifies the set identifier of the following messages until
the next $set or end-of-file appears. The argument n is the set
identifier which is defined as a number in the range [1, (NL_SETMAX)].
Set identifiers must occur in ascending order within a single source
file, but need not be contiguous. Any string following a space
following the set identifier is treated as a comment. If no $set
directive is specified in a given source file, all messages will be
located in the default message set NL_SETD.
$del n comment
This line deletes messages from set n from a message catalog. The n
specifies a set number. Any string following a space following the
set number is treated as a comment.
A line beginning with $ followed by a space is treated as a comment.
A message line consists of a message identifier m in the range [1,
(NL_MSGMAX)]. The message-text is stored in the message catalog with
the set identifier specified by the last $set directive, and the
message identifier m. If the message-text is empty, and there is a
space character following the message identifier, an empty string is
stored in the message catalog. If the message-text is empty, and if
there is no space character following the message identifier, then the
existing message in the current set with the specified message
identifier is deleted from the catalog. Message identifiers must be
in ascending order within a single set, but need not be contiguous.
The message-text length must be in the range [0, (NL_TEXTMAX)].
This line specifies an optional quote character c which can be used to
surround message-text so that trailing space or empty messages are
visible in message source files. By default, or if an empty $quote
directive is specified, no quoting of message-text will be recognized.
Empty lines in message source files are ignored. The effect of lines
beginning with any character other than those described above is undefined.
Text strings can contain the following special characters and escape
sequences. In addition, if a quote character is defined, it may be escaped
as well to embed a literal quote character.
\n line feed
\t horizontal tab
\v vertical tab
\r carriage return
\f form feed
\ooo octal number in the range [000, 377]
A backslash character immediately before the end of the line in a file is
used to continue the line onto the next line, e.g.:
1 This line is continued \
on this line.
If the character following the backslash is not one of those specified, the
backslash is ignored.
The gencat utility exits 0 on success, and >0 if an error occurs.
catclose(3), catgets(3), catopen(3)
The gencat utility is compliant with the X/Open Portability Guide Issue 4

A message catalog file created from a blank input file cannot be revised;
it must be deleted and recreated.
