重命名文件名的另一个名字 [英] Rename filename to another name

问题描述

非常简单的解释：

如何重命名

/folder1/something.test.html
/folder1/somethingElse.test.html
/folder2/againsomething.test.html
/canBeHereAlso.test.html

到

/folder1/something.test2.html
/folder1/somethingElse.test2.html
/folder2/againsomething.test2.html
/canBeHereAlso.test2.html

和还逆功能，以便能够回来原点

and also the inverse-function to be able to come back at the original point ?

这样的东西是很简单，但不幸的是，完全不可能谷歌它们，除非你已经知道怎么做了......

This kind of things are really simple but unfortunately, completely impossible to Google them, unless you know already how to do it...

我在想：

for NAME in */*.test.html; do mv $NAME $NAME2.html ; done # for A -> B

for NAME in */*.test2.html ; do mv $NAME #remove last caracter.html for B --> A

但不幸的是，它不是那么简单......

But unfortunately, it's not that simple...

推荐答案

有关简单的字符串后缀，preFIX操纵，我建议你熟悉shell的标准的参数扩展功能 $ {VAR％suffix_to_remove} 和 $ {VAR＃prefix_to_remove} 。这些将在任何标准的工作 SH ，而不仅仅是庆典：

For simple string suffix and prefix manipulation, I suggest you familiarize yourself with the shell's standard parameter expansion features ${VAR%suffix_to_remove} and ${VAR#prefix_to_remove}. These will work on any standard sh, not just bash:

的测试 - >测试2 的

for NAME in */*.test.html; do      # NAME is, e.g., "dir/foo.test.html"
  BASENAME=${NAME%.test.html}      # BASENAME is "dir/foo"
  mv "$NAME" "$BASENAME.test2.html";
done

的测试2 - >测试的是相似的：

  ...
  BASENAME=${NAME%.test2.html}      # strip off .test2.html
  ...

您也可以使用标准shell实用工具 基本名 和 目录名 来实现类似的东西。

You could also use the standard shell utilities basename and dirname to achieve something similar.
