findmsg, dumpmsg — create message catalog file for modification


findmsg [-aiv] [[-D sym] [-U sym]] file ...

dumpmsg file ...


The findmsg command extracts messages from a C program source file and writes them to the standard output in a format suitable for input to gencat (see gencat(1)). The input file will be preprocessed using cpp (see cpp(1)) in order to select print specifiers and handle ifdef, ifndef... conditional cpp primitives. If multiple input files are specified and the -a option is not used, the files are processed sequentially such that message catalog comment lines identifying the input file are written before the output for each input file.

The findmsg command scans the source files for uncommented lines with one of the following three formats embedded within it:

catgets(any_var,NL_SETN,n,<message>) <message> /* catgets n */ /* catgets n */ <message>

or any combination of these formats wholly contained on a single physical line. <message> could be a string constant or a combination of string constants and print specifiers (PRI*). Any number of spaces or tabs can separate the catgets comment from the message. The digit n, which can be any valid message number (see gencat(1)), is combined with the message string to produce a message catalog source line. The message source line is assigned to the set whose number is the current value of NL_SETN as set by the last #define directive encountered. If NL_SETN has not yet been defined when a message line is found, the message is output without a set number specification. If more than one message is found belonging to the same set and message number, the last message found is output; any others are silently discarded. Conditional compilation and #include instructions in the C source files are ignored.


findmsg recognizes the following command-line options:


Merge identically numbered sets from multiple input files so that gencat can process the findmsg output.


Define symbol sym.


Cause symbol sym to be undefined.


Consider all #ifdefs to extract messages from the input file. Options -D and -U will be used to select print specifiers if this option is not used.


Outputs all error messages issued by cpp. By default, findmsg does not display the error messages issued by cpp.

The dumpmsg command extracts messages from a message catalog file created by gencat. Messages are written to standard output in a format suitable for editing and re-input to gencat.


Environment Variables

LC_CTYPE determines the interpretation of messages as single-byte and/or multi-byte characters.

LC_MESSAGES determines the language in which messages are displayed.

If LC_CTYPE or LC_MESSAGES is not specified in the environment or is set to the empty string, the value of LANG is used as a default for each unspecified or empty variable. If LANG is not specified or is set to the empty string, a default of C (see lang(5)) is used instead of LANG. If any internationalization variable contains an invalid setting, findmsg and dumpmsg behave as if all internationalization variables are set to C. See environ(5).

International Code Set Support

Single-byte and multi-byte character code sets are supported.


The findmsg and dumpmsg commands are HP proprietary, not portable to other vendors' systems, and will not be provided in future HP-UX releases.


findmsg and dumpmsg were developed by HP.
