总结命令

我如何将这些命令总结或浓缩为单个命令以保留其功能？

您可以使用嵌套for循环，外层循环用于源索引（$i），内层循环用于目标索引（$n）：

for i in {1..16}; do
  # Skip if no files found in $i/
  ls $i/*.jpg &> /dev/null || continue
  for n in {0..4}; do
      target="../../5folds_all/augmented_images/${n}/train/$(printf "%03d" $i)"
      # create target folder if not exists
      mkdir -p "$target"
      # copy to target folder
      cp $i/*.jpg "$target"
  done
done
