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.

• 定制的find命令

find-regex() {
    # find-regex $path $pattern
    if [ $# = 0 ]; then                                                                                     
        echo "Usage: find-regex $path $pattern"
    else
        find "$1" -regextype posix-egrep -regex "$2"
    fi  
}

• man find
