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".
但它不起作用。正则表达式有问题吗？有人可以帮我解决这个问题吗？
最佳答案
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
