我最近读了一些bash代码,echo $“asdf”,什么是$for?


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.
