我看到 zsh 的一个问题，其中变量中的 glob 字符没有像我预期的那样扩展。下面的例子可以更好地解释它。
$ echo $0
-bash
$ echo $HOME/Downloads/zsh-test/*
/Users/bruce/Downloads/zsh-test/file1 /Users/bruce/Downloads/zsh-test/file2 /Users/bruce/Downloads/zsh-test/file3 /Users/bruce/Downloads/zsh-test/file4
$ file=*; echo $HOME/Downloads/zsh-test/$file
/Users/bruce/Downloads/zsh-test/file1 /Users/bruce/Downloads/zsh-test/file2 /Users/bruce/Downloads/zsh-test/file3 /Users/bruce/Downloads/zsh-test/file4
Macbook% echo $0
zsh
Macbook% echo $HOME/Downloads/zsh-test/*
/Users/bruce/Downloads/zsh-test/file1 /Users/bruce/Downloads/zsh-test/file2 /Users/bruce/Downloads/zsh-test/file3 /Users/bruce/Downloads/zsh-test/file4
Macbook% file=*; echo $HOME/Downloads/zsh-test/$file
/Users/bruce/Downloads/zsh-test/*
我原以为最后一个命令会像在 bash 中那样扩展。知道我做错了什么吗？
