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"命令查找所有这些图像:
find . -regex "[a-f0-9\-]\{36\}\.jpg".
但它不起作用.正则表达式有问题吗？有人能帮我吗？

find . -regextype sed -regex ".*/[a-f0-9\-]\{36\}\.jpg"
请注意，您需要在开头指定.*/，因为find匹配整个路径.
例子:
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
