java 正则表达式find_如何使用正则表达式与find命令？

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

请注意，您需要在开头指定 .*/ ，因为 find 与整个路径匹配 .

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
