linux - find 命令使用posix-egrep, 不好使

Question

问题

根据我的了解, find中一般使用shell通配符, 但是shell通配符的表达能力不是很强, 所以就想使用正则, 但是结果不如人意.

查阅了文档, 自认为是按照文档的描述做的, 不知问题出在何处.

        echo "Usage: find-regex $path $pattern"

There is no problem with the usage. The reason why you don't get the result you want may be because "" the special characters in $2 contained in double quotes may be interpreted by the shell.
