在linux中查找没有扩展名的文件并批量重命名它们

Question

我的服务器上有一堆文件，如下所示。我需要编写一个脚本将所有文件从 JPG 重命名为 .jpg 正如您所看到的，其中一些已经具有 .jpg 扩展名，而另一些则没有。

你能帮助我吗？我可以通过 bash 或通过 php 来完成，无论哪个更容易，我只是不知道如何做。

谢谢杰森

Answer 1

find . -name '*JPG.jpg' -print0 | xargs -0 rename JPG.jpg .jpg
find . -name '*JPG' -print0 | xargs -0 rename JPG .jpg

rename(1) 是 util-linux 的标准工具

Answer 2

给定示例中的文件名模式，这将解决问题：

for F in *[0-9]JPG; do mv $F $F.jpg; done

如果您需要递归解决方案：

find . -name "*[0-9]JPG" -exec mv \{\} \{\}.jpg \;

Answer 3

重击4

#!/bin/bash
shopt -s globstar
for file in **/*JPG
do
  mv "$file" "${file/JPG/.jpg}"
done

Answer 4

这只是松散地未经测试，但应该可以工作......

printf '#!/bin/sh\nmv -v $1 "$1".jpg' > addext.sh
chmod u+x addext.sh
find . -type f -name "*[0-9]JPG"  -exec ${PWD}/addext.sh "{}" ";"

假设您正在使用 GNU 工具运行（您将是这样，因为您已将问题标记为 linux）。

Answer 5

我会去找这只野兽。不是最优雅的版本，但会重命名任何以（不区分大小写）JPG.jpg 结尾的文件

find . -type f | grep -i -E '(JPG)*\.*(JPG)+
 | while read file ; do mv $file `echo $file | perl -pe 's!(JPG)*\.*(JPG)+$!.jpg!gi'`; done
