touch command create multiple files (different names) under one directory

Question

I wanted to make a script that creates a directories and files structure in bash.

I tried something like this:

"mkdir -p 1/2 && touch 1/2/{a b c}"

a,b,c should be files created in one command or something..

but for some reason the structure goes like this

current folder: b c 1

1: 2

2: a

touch can't be used to create multiple files with different names in one directory?

Answer 1

我建议添加, ：

mkdir -p 1/2 && touch 1/2/{a,b,c}

Answer 2

mkdir -p 1/2 && touch 1/2/{a,b,c}

The commas are essential, otherwise it is evaluated to 1/2/{abc} . Whitespace is only allowed in such patterns if it is escaped:

echo a{1\ 2\ 3,4} # echo a1 2 3 a4

Answer 3

如果您不喜欢逗号或需要按顺序创建文件名，请使用“ ..”

mkdir -p 1/2 && touch 1/2/{a..c}
