linux – 从各种目录中随机选择一个文件并进行排序

基础：

从1个目录中随机选择文件：

shuf -n1 –e *

从1目录中选择第一个文件：

ls | sort -n | head -1

例：

更新：文件结构/真实文件名格式(这只是几个文件,有几百个)

初始订单：

我想要生成的输出/结果(随机调整文件,但保持数字顺序)：

要将结果存储在名为filename的文件中,您可以重定向：

$find $target -type f -iname "*.txt" \
   | shuf \
   | awk -F- '{printf("%s:%s\n", $0, $NF)}' \
   | sort -t : -k 2 -s \
   | cut -d : -f 1 \
   | xargs -n1 basename \
   | sed "s,^,$destination," \
   > filename
