我最近看了一些bash代码，echo $"asdf"，$是做什么用的？
$"asdf" 和 "asdf" 有什么区别？
最佳答案
如 bash manual 中所述，它用于本地化:
A double-quoted string preceded by a dollar sign (‘$’) will cause the string to be translated according to the current locale. If the current locale is C or POSIX, the dollar sign is ignored. If the string is translated and replaced, the replacement is double-quoted.
