One command to create 26 empty files:
创建 26 个空文件的一个命令：
touch {a..z}.txt
or 152:

touch {{a..z},{A..Z},{0..99}}.txt
A small loop to create 152 files with some contents:

You can do numbered files with leading zeros:
您可以使用前导零来编号文件：
for i in {0..100}
do
echo hello > "File$(printf "%03d" "$i").txt"
done
or, in Bash 4:
或者，在 Bash 4 中：
for i in {000..100}
do
echo hello > "File${i}.txt"
done

You can create a file using $ cat > a.txt. If you need to have a file with specific content, type $ echo content > filename.
您可以使用$ cat > a.txt. 如果您需要具有特定内容的文件，请键入$ echo content > filename.
