文件名如下：

1970_01_01_00_05_07_picture_000000231.jpg1970_01_01_00_05_08_picture_000000232.jpg1970_01_01_00_05_10_picture_000000233.jpg1970_01_01_00_05_11_picture_000000234.jpg1970_01_01_00_05_12_picture_000000235.jpg1970_01_01_00_05_13_picture_000000236.jpg1970_01_01_00_05_14_picture_000000237.jpg1970_01_01_00_05_15_picture_000000238.jpg1970_01_01_00_05_16_picture_000000239.jpg1970_01_01_00_05_18_picture_000000240.jpg1970_01_01_00_05_19_picture_000000241.jpg1970_01_01_00_05_20_picture_000000242.jpg1970_01_01_00_05_21_picture_000000243.jpg1970_01_01_00_05_22_picture_000000244.jpg1970_01_01_00_05_23_picture_000000245.jpg1970_01_01_00_05_25_picture_000000246.jpg1970_01_01_00_05_26_picture_000000247.jpg1970_01_01_00_05_27_picture_000000248.jpg1970_01_01_00_05_28_picture_000000249.jpg

结果查询到在某时间段自己想要的文件名，及图片

            for(int i=0; i<100; i++)    //删除最早的抓拍图片100张
            {
                system("rm -f /sddisk/picture/$(ls /sddisk/picture -rt | sed -n '1p')");
            }
