Previous: , Up: Quoting   [Contents][Index] Locale-Specific Translation

Prefixing a double-quoted string with a dollar sign (‘$’), such as $"hello, world", will cause the string to be translated according to the current locale. The gettext infrastructure performs the lookup and translation, using the LC_MESSAGES, TEXTDOMAINDIR, and TEXTDOMAIN shell variables, as explained below. See the gettext documentation for additional details not covered here. If the current locale is C or POSIX, if there are no translations available, of if the string is not translated, the dollar sign is ignored. Since this is a form of double quoting, the string remains double-quoted by default, whether or not it is translated and replaced. If the noexpand_translation option is enabled using the shopt builtin (see The Shopt Builtin), translated strings are single-quoted instead of double-quoted.

The rest of this section is a brief overview of how you use gettext to create translations for strings in a shell script named scriptname. There are more details in the gettext documentation.
