zsh：未知文件屬性

Question

我在我的.zshrc中有以下功能，理論上它允許我寫入提交消息而不需要引號。

cm(){ 
    git commit -m "$@" 
} 

當我運行它（cm foo bar），我收到以下錯誤：

zsh: unknown file attribute 

是否$@意味着zsh的同樣的事情，因爲它在bash呢？

Answer 1

認可爲this文章，*和@都包含位置參數數組。

The parameters * , @ and argv are arrays containing all the positional parameters; thus $argv[n] , etc., is equivalent to simply $n .

而且......

A subscript of the form [*] or [@] evaluates to all elements of an array; there is no difference between the two except when they appear within double quotes. "$foo[*]" evaluates to "$foo[1] $foo[2] ..." , whereas "$foo[@]" evaluates to "$foo[1]" "$foo[2]" ... .
