如何在find命令中使用正则表达式？

linux

我有一些用生成的uuid1字符串命名的图像。例如81397018-b84a-11e0-9d2a-001b77dc0bed.jpg。我想使用“查找”命令找出所有这些图像：

find . -regex "[a-f0-9\-]\{36\}\.jpg".

但这是行不通的。正则表达式有问题吗？有人可以帮我吗？

find . -regextype sed -regex ".*/[a-f0-9\-]\{36\}\.jpg"

请注意，.*/由于find与整个路径匹配，因此需要在开头指定。

例：

susam@nifty:~/so$ find . -name "*.jpg"
./foo-111.jpg
./test/81397018-b84a-11e0-9d2a-001b77dc0bed.jpg
./81397018-b84a-11e0-9d2a-001b77dc0bed.jpg
susam@nifty:~/so$ 
susam@nifty:~/so$ find . -regextype sed -regex ".*/[a-f0-9\-]\{36\}\.jpg"
./test/81397018-b84a-11e0-9d2a-001b77dc0bed.jpg
./81397018-b84a-11e0-9d2a-001b77dc0bed.jpg
