重命名多个文件外壳 [英] Rename multiple files shell

问题描述

我在一个目录多个文件，例如： linux_file1.mp4 ， linux_file2.mp4 等。如何移动这些文件，使用的外壳，使名称 file1.mp4 ， file2.mp4 等上。我有大约30个文件，我想移动到新的名称。

I have multiple files in a directory, example: linux_file1.mp4, linux_file2.mp4 and so on. How do I move these files, using shell, so that the names are file1.mp4, file2.mp4 and so on. I have about 30 files that I want to move to the new name.

推荐答案

我喜欢 MMV 为这种事情

mmv 'linux_*' '#1'

但你也可以使用改名。要知道，有常用的两个改名具有非常不同的语法命令。一种是用Perl编写的，另一种是分布有UTIL Linux的，所以我分辨他们是重命名的perl和重命名UTIL的。

But you can also use rename. Be aware that there are commonly two rename commands 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.

使用Perl的重命名：

With Perl rename:

rename 's/^linux_//' linux_*.mp4

由于cweiske正确地指出。

As cweiske correctly pointed out.

通过UTIL重命名：

rename linux_ '' linux_*.mp4

你怎么知道哪个重命名你有吗？尝试运行重命名-V ;如果你的版本UTIL将其重命名将打印版本号，如果是perl的重命名，将无害报告和未知的选项，并显示使用。

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.

如果你没有任何改名或 MMV 并不愿或无法安装他们仍然可以用普通老贝code实现这一点：

If you don't have either rename or mmv and don't want to or can't install them you can still accomplish this with plain old shell code:

for file in linux_*.mp4 ; do mv "$file" "${file#linux_}" ; done

此语法将与任何POSIX SH符合XPG4或更高版本，这是基本上所有的炮弹，这些天的工作。

This syntax will work with any POSIX sh conforming to XPG4 or later, which is essentially all shells these days.
