Rename multiple files in bash
提问by andPat
I have A.js, B.js, C.jsin a certain directory and I want to write a SINGLE command line in bash shell to rename these files _A, _B, _C. How can I do this?
我有A.js, B.js,C.js在某个目录中，我想在 bash shell 中编写一个单一的命令行来重命名这些文件 _A、_B、_C。我怎样才能做到这一点？
I tried find -name '*.sh' | xargs -I file mv file basename file .shbut it doesn't work, basename file .sh isn't recognized as a nested command
我试过了，find -name '*.sh' | xargs -I file mv file basename file .sh但它不起作用，basename 文件 .sh 不被识别为嵌套命令

How about
怎么样
rename 's/(.*).js/_/' *.js
Check the syntax for rename on your system.
检查系统上的重命名语法。
The above command will rename A.jsto _A& so on.
上面的命令将重命名A.js为_A& 等等。
If you want to retain the extension, below should help:
如果您想保留扩展名，以下应该有所帮助：
rename 's/(.*)/_/' *.js

Assuming you still want to keep the extension on the files, you could do this:
假设您仍想保留文件的扩展名，您可以这样做：
$ for f in * ; do mv "$f" _"$f" ; done
It will get the name of each file in the directory, and prepend an "_".
它将获取目录中每个文件的名称，并在前面加上“_”。

A simple native way to do it, with directory traversal:
一种简单的原生方式，通过目录遍历：
find -type f | xargs -I {} mv {} {}.txt
Will rename every file in place adding extension .txt at the end.
将重命名每个文件，在末尾添加扩展名 .txt。
And a more general cool way with parallelization:
还有一种更通用的并行化方式：
find -name "file*.p" | parallel 'f="{}" ; mv -- {} ${f:0:4}change_between${f:8}'
