The mkmsgs utility is used to create a file of text strings that can be accessed using the text retrieval tools (see gettxt(1), srchtxt(1), exstr(1), and gettxt(3C)). It will take as input a file of text strings for a particular geographic locale (see setlocale(3C)) and create a file of text strings in a format that can be retrieved by both gettxt(1) and gettxt(3C). By using the -i option, you can install the created file under the /usr/lib/locale/locale/LC_MESSAGES directory (locale corresponds to the language in which the text strings are written).
inputstrings is the name of the file that contains the original text strings. msgfile is the name of the output file where mkmsgs
writes the strings in a format that is readable by gettxt(1) and gettxt(3C). The name of msgfile can be up to 14 characters in length,
but may not contain either \0 (null) or the ASCII code for / (slash) or : (colon).
The input file contains a set of text strings for the particular geographic locale. Text strings are separated by a newline character. Nongraphic characters must be represented as alphabetic escape
sequences. Messages are transformed and copied sequentially from inputstrings to msgfile. To generate an empty message in msgfile,
leave an empty line at the correct place in inputstrings.
Strings can be changed simply by editing the file inputstrings. New strings must be added only at the end of the file; then a new msgfile file
must be created and installed in the correct place. If this procedure is not followed, the retrieval function will retrieve the wrong string and software compatibility will be broken.
