Rename multiple files in shell
提问by elzwhere
I have multiple files in a directory, example: linux_file1.mp4, linux_file2.mp4and so on. How do I move these files, using shell, so that the names are file1.mp4, file2.mp4and so on. I have about 30 files that I want to move to the new name.
我在一个目录中有多个文件，例如：linux_file1.mp4，linux_file2.mp4等等。如何使用 shell 移动这些文件，以便名称为file1.mp4，file2.mp4等等。我有大约 30 个文件要移动到新名称。

I like mmvfor this kind of thing
我喜欢这种事情的mmv
mmv 'linux_*' '#1'
But you can also use rename. Be aware that there are commonly two renamecommands with very different syntax. One is written in Perl, the other is distributed with util-linux, so I distinguish them as "perl rename" and "util rename" below.
但您也可以使用rename. 请注意，通常有两个rename命令具有非常不同的语法。一个是用 Perl 写的，另一个是用 util-linux 分发的，所以我在下面将它们区分为“perl rename”和“util rename”。
With Perl rename:
使用 Perl 重命名：
rename 's/^linux_//' linux_*.mp4
As cweiske correctly pointed out.
正如 cweiske 正确指出的那样。
With util rename:
使用 util 重命名：
rename linux_ '' linux_*.mp4
How can you tell which rename you have? Try running rename -V; if your version is util rename it will print the version number and if it is perl rename it will harmlessly report and unknown option and show usage.
你怎么知道你有哪个重命名？尝试运行rename -V；如果您的版本是 util rename，它将打印版本号，如果是 perl rename，它将无害地报告和未知选项并显示使用情况。
If you don't have either renameor mmvand don't want to or can't install them you can still accomplish this with plain old shell code:
如果您没有rename或mmv不想安装它们，您仍然可以使用普通的旧 shell 代码完成此操作：
for file in linux_*.mp4 ; do mv "$file" "${file#linux_}" ; done
This syntax will work with any POSIX sh conforming to XPG4 or later, which is essentially all shells these days.
此语法适用于任何符合 XPG4 或更高版本的 POSIX sh，现在基本上都是 shell。

$ rename 's/linux_//' linux_*.mp4
回答by dtrckd
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 -- {} ${f:0:10}trump${f:4}'

I was able to achieve replace filenames within directories by combining @dtrckd and @Sorpigal answers.
通过结合@dtrckd 和@Sorpigal 答案，我能够实现替换目录中的文件名。
for file in `find -name "linux_*.mp4"`; do mv "$file" "${file/linux_/}" ; done
