问题描述
我在目录中有多个文件，例如:linux_file1.mp4，linux_file2.mp4等.如何使用Shell移动这些文件，以使名称为file1.mp4，file2.mp4等.我大约有30个文件要移到新名称.
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 用于这种事情
mmv 'linux_*' '#1'
但是您也可以使用rename.请注意，通常有两个rename命令的语法非常不同.一种是用Perl编写的，另一种是用util-linux分发的，因此在下面将它们区分为"perl重命名"和"util重命名".
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重命名:
rename 's/^linux_//' linux_*.mp4
正如cweiske正确指出的那样.
As cweiske correctly pointed out.
使用util重命名:
rename linux_ '' linux_*.mp4
如何知道您拥有的重命名?尝试运行rename -V;如果您的版本是util重命名，它将打印版本号；如果是perl重命名，它将无害地报告和未知选项并显示用法.
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.
如果您没有rename或mmv，并且不想或无法安装它们，您仍然可以使用简单的旧shell代码来完成此操作:
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
此语法将与所有符合XPG4或更高版本的POSIX sh一起使用，这实际上是当今的所有shell.
This syntax will work with any POSIX sh conforming to XPG4 or later, which is essentially all shells these days.
