Question

到目前为止，我有这个，我在所选文件夹中创建了我想要的文件夹数量。创建的文件夹数量取决于我的选择。
如何在每个文件夹中制作文件？我希望它们根据我选择的文件数量从 1 开始编号。

read -p "Enter the number of folders to create: " FOLDER_X
read -p "Enter the number of files to create: " FILE_Y

for (( x = 1; x <= FOLDER_X; x++ )); do 
mkdir $DIRY/$x

done

do
echo hello > "$i.txt"
done

#!/bin/bash

shopt -s extglob
DIR=/path/to/somewhere

while :; do
    read -p "Enter the number of folders to create: " folders
    read -p "Enter the number of files to create: " files
    [[ $folders,$files == +([[:digit:]]),+([[:digit:]]) ]] && break
    echo "Please provide numeric inputs."
done

for (( i = 0; i < folders; ++i )); do
    mkdir -p "$DIR/$i" || break

    for (( j = 0; j < files; ++j )); do
        echo hello > "$DIR/$i/$j.txt" || break 2
    done
done
