shell - 重命名目录中的文件而不重新键入目录名称

Question

假设我们有一个文件test.txt，my_directory我想将其重命名为yeah.txt. 有没有办法zsh（甚至只是bash知道）避免重新输入my_directory？

我发现以下内容有点长：

mv my_directory/test.txt my_directory/yeah.txt

谢谢。

Answer 1

我会用大括号扩展来做到这一点：

mv my_directory/{test,yeah}.txt

Answer 2

我已copy-prev-shell-word分配给^P

% cp my_directory/test.txt [^P] # expands to....
% cp my_directory/test.txt my_directory/test.txt

然后我只是手动编辑最后一个参数。对我来说，这是一个比大括号扩展更好的解决方案，但我认为这只是一种偏好。

如果有兴趣，您应该查看以下函数之一 ( man zshzle)：

copy-prev-word (ESC-^_) (unbound) (unbound)
 Duplicate the word to the left of the cursor.

copy-prev-shell-word
 Like  copy-prev-word,  but  the  word  is  found  by  using  shell  parsing,
 whereas copy-prev-word  looks for blanks. This makes a difference when the 
 word is quoted and contains spaces.

我用它来绑定函数bindkey -M emacs "^p" copy-prev-shell-word
