我最近读了一些bash代码,echo $“asdf”,什么是$for？
$“asdf”和“asdf”有什么区别？
如
bash manual中所述,它用于本地化：
原文链接：https://www.f2er.com/bash/387070.htmlA double-quoted string preceded by a dollar sign (‘$’) 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.
