在Mac上批量重命名文件正则表达式 [英] Batch rename files regular expression on Mac

问题描述

我正在尝试批量重命名PDF文件，以从右到左删除所有字符，直到在Mac OS上达到数字字符为止.

I'm trying to batch rename PDF files to remove all characters from right to left until a numeric character is reached on Mac OS.

例如:

10002ASmith.pdf> 10002.pdf

10002ASmith.pdf > 10002.pdf

1023AJones.pdf> 1023.pdf

1023AJones.pdf > 1023.pdf

文件开头的数字长度是可变的，因此我认为最好将regex从右到左重命名，直到达到数字为止.

The numeric length in the beginning of the files is variable so I figure would be best to have regex rename from right to left until a number is reached.

我知道Mac Yosemite具有批量重命名功能，但是没有看到正则表达式重命名选项.在终端中执行此操作是否容易?如果可以，如何操作?或者我可以使用免费的程序来使用正则表达式吗?

I know Mac Yosemite comes with batch rename capabilities but didn't see a regex rename option. Is it easy to do this in terminal and if so how, or is there a free program I can use to use a regular expression?

我想我只需要知道实际的正则表达式是什么，因为我对regex的经验还很远.

I suppose I just need to know what the actual regular expression would be since I'm far from experienced in regex.

谢谢您的帮助！

推荐答案

您可以将这个 find 与 sed 一起使用:

You can use this find with sed:

cd to /path/of/pdfs

while IFS= read -rd '' line; do
   echo mv "$line" $(sed 's~\./[a-zA-Z]*\([0-9]*[a-zA-Z]\).*\(\.pdf\)$~\1\2~' <<< "$line")
done < <(find . -maxdepth 1 -regex '\./[a-zA-Z]*[0-9]*[a-zA-Z]\{1,\}\.pdf$' -print0)

确认其正常运行后，

删除 echo .

Remove echo after you verify it is working.
