NAME
mkmsgs - create message files for use by gettxt() SYNOPSIS
locale] textfile msgfile DESCRIPTION
The command takes as input a file of localized text strings and generates a message file that can be accessed by the gettxt(3C) routine. textfile is the name of the file that contains the text strings. msgfile is the name of the output message file. appends the suffix to the message file name. The combined length of the file name should be less than 14 bytes for short file name file system. The msgfile file should not contain a colon since it will confuse the formatting routines. The textfile file contains the localized text strings. The text strings are separated by a newline character. The text strings are pro- cessed sequentially and copied to the msgfile message file. An empty line in the input results in a corresponding empty message written to the msgfile message file. Options The command supports the following options: Overwrite the msgfile message file if it exists. The msgfile message file is installed in the system-wide localization directory corresponding to the specified locale. Only a user with the appropriate privileges can create or overwrite the message file in that directory. The direc- tory will be created if it does not exist. EXTERNAL INFLUENCES

If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multibyte character code sets are supported. EXAMPLES
