        echo "less than five min ========== " $1
    else
        echo timestamp $timestamp
        echo filetimes $filetimestamp
        echo during is $[$timestamp - $filetimestamp]

    do
        if [ -d $1"/"$file ]; then
            #echo in "-d file " $file
            if [[ $file != '.' && $file != '..' ]]; then
                #echo in "-------------------------------------- file " $file
                read_dir $1"/"$file
            #else
            #    echo "else iiii file is " $file
            fi

        else
            #echo "else-->>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> "  $1"/"$file
