查找文件，将其重命名为unix bash [英] Find files, rename in place unix bash

问题描述

这应该是相对琐碎的，但是我已经尝试了一段时间没有多大的运气了.我有一个目录，其中包含许多子目录，每个子目录都有自己的结构和文件.

This should be relatively trivial but I have been trying for some time without much luck. I have a directory, with many sub-directories, each with their own structure and files.

我正在寻找工作目录下任何目录中的所有 .java 文件，并将它们重命名为特定名称.例如，我想将所有Java文件命名为 test.java .

I am looking to find all .java files within any directory under the working directory, and rename them to a particular name. For example, I would like to name all of the java files test.java.

如果目录结构如下:

./files/abc/src/abc.java
./files/eee/src/foo.java
./files/roo/src/jam.java

我想简单地重命名为:

./files/abc/src/test.java
./files/eee/src/test.java
./files/roo/src/test.java

我的问题的一部分是路径中可能有空格.我不必担心重命名类或文件中的任何内容，只需重命名文件名即可.

Part of my problem is that the paths may have spaces in them. I don't need to worry about renaming classes or anything inside the files, just the file names in place.

如果目录中有多个 .java 文件，我不介意文件是否被覆盖或给出提示以选择要执行的操作(既可以，也可以每个目录中不可能有多个目录.

If there is more than one .java file in a directory, I don't mind if it is overwritten, or a prompt is given, to choose what to do (either is OK, it is unlikely that there are more than one in each directory.

我尝试过的事情:

我研究了 mv 和 find ；但是，当我将它们连接在一起时，我似乎做错了.我要确保将文件保留在当前位置并重命名，而不要移动.

I have looked into mv and find; but, when I pipe them together, I seem to be doing it wrong. I want to make sure to keep the files in their current location and rename, and not move.

推荐答案

GNU版本的 find 具有 -execdir 操作，可将目录更改为文件所在的位置.

The GNU version of find has an -execdir action which changes directory to wherever the file is.

find . -name '*.java' -execdir mv {} test.java \;

如果您的 find 版本不支持 -execdir ，则可以通过以下方式完成工作:

If your version of find doesn't support -execdir then you can get the job done with:

find . -name '*.java' -exec bash -c 'mv "$1" "${1%/*}"/test.java' -- {} \;
