gencat(1) User Commands gencat(1)NAMEgencat - generate a formatted message catalog
SYNOPSISgencat catfile msgfile...
DESCRIPTION
The gencat command merges the message text source file(s) msgfile into
a formatted message database catfile. The database catfile is created
if it does not already exist. If catfile does exist, its messages are
included in the new catfile. If set and message numbers collide, the
new message-text defined in msgfile replaces the old message text cur‐
rently contained in catfile. The message text source file (or set of
files) input to gencat can contain either set and message numbers or
simply message numbers, in which case the set NL_SETD (see
nl_types.h(3HEAD)) is assumed.
Message Text Source File Format
The format of a message text source file is defined as follows. Note
that the fields of a message text source line are separated by a single
ASCII space or tab character. Any other ASCII spaces or tabs are con‐
sidered as part of the subsequent field.
$set n comment Where n specifies the set identifier of the
following messages until the next $set,
$delset, or end-of-file appears. n must be a
number in the range (1-{NL_SETMAX}). Set iden‐
tifiers within a single source file need not be
contiguous. Any string following the set iden‐
tifier is treated as a comment. If no $set
directive is specified in a message text source
file, all messages are located in the default
message set NL_SETD.
$delset n comment Deletes message set n from an existing message
catalog. Any string following the set number is
treated as a comment. (Note: if n is not a
valid set it is ignored.)
$comment A line beginning with a dollar symbol $ fol‐
lowed by an ASCII space or tab character is
treated as a comment.
m message-text The m denotes the message identifier, a number
in the range (1-{NL_MSGMAX}). The message-text
is stored in the message catalog with the set
identifier specified by the last $set direc‐
tive, and with message identifier m. If the
message-text is empty, and an ASCII space or
tab field separator is present, an empty string
is stored in the message catalog. If a message
source line has a message number, but neither a
field separator nor message-text, the existing
message with that number (if any) is deleted
from the catalog. Message identifiers need not
be contiguous. The length of message-text must
be in the range (0-{NL_TEXTMAX}).
$quote c This line specifies an optional quote character
c, which can be used to surround message-text
so that trailing spaces or null (empty) mes‐
sages are visible in a message source line. By
default, or if an empty $quote directive is
supplied, no quoting of message-text will be
recognized.
Empty lines in a message text source file are ignored.
Text strings can contain the special characters and escape sequences
defined in the following table:
┌──────────────────────────────────────────────────────────────┐
│Description Symbol Sequence │
│newline NL(LF) \n │
│horizontal tab HT \t │
│vertical tab VT \v │
│backspace BS \b │
│carriage return CR \r │
│form feed FF \f │
│backslash \ \\ │
│bit pattern ddd \ddd │
└──────────────────────────────────────────────────────────────┘
The escape sequence \ddd consists of backslash followed by 1, 2 or 3
octal digits, which are taken to specify the value of the desired char‐
acter. If the character following a backslash is not one of those spec‐
ified, the backslash is ignored.
Backslash followed by an ASCII newline character is also used to con‐
tinue a string on the following line. Thus, the following two lines
describe a single message string:
1 This line continues \
to the next line
which is equivalent to:
1 This line continues to the next line
OPERANDS
The following operands are supported:
catfile A path name of the formatted message catalog. If − is
specified, standard output is used.
msgfile A path name of a message text source file. If − is
specified for an instance of msgfile, standard input is
used. The format of message text source files is
defined in Message Text Source File Format.

that affect the execution of gencat: LANG, LC_ALL, LC_CTYPE, LC_MES‐
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
