#!/bin/bash

function delete_file()

    INTERVAL=$(($1*3600*24))

            fi

    return 0;


function getdir()

    for element in `ls $2`
    do  
        dir_or_file=$2"/"$element
        if [ -d $dir_or_file ]
        then
            echo $dir_or_file
            delete_file $1 $dir_or_file
            getdir $1 $dir_or_file
        else
        #delete_file $2 $dir_or_file
            echo "clear finished"
        fi  
    done
    return 0;


root_dir="."
function main()

    getdir $1 $root_dir
    ret=$?
    echo "getdir run ret:$ret"


main $@

使用时shell输入参数删除当前目录7天前的目录或文件

./delest_images 7
