linux - 路径中转义和引用空格有什么区别？

Question

这是我的代码:

cp "./somepath/somefile.ext" ~/Library/MobileDevice/Provisioning\ Profiles/

echo "fail here"
ls -l ~/Library/MobileDevice/Provisioning\ Profiles/
echo "but success here"
ls -l "~/Library/MobileDevice/Provisioning Profiles/"

当第一个找到这个目录时，为什么第二个 ls 返回 ls: ~/Library/MobileDevice/Provisioning Profiles/: No such file or directory？

花了几个小时来调试此功能，但无法理解其中的区别。

让我们问ShellCheck :

In yourscript line 6:
ls -l "~/Library/MobileDevice/Provisioning Profiles/"
       ^-- SC2088: Note that ~ does not expand in quotes.

它goes on to explain要结合 ~ 和引号，你可以将 ~ 放在外面:

ls -l ~/"Library/MobileDevice/Provisioning Profiles/"
