Making a directory with multiple directories

So a bit of a stupid question, I know in linux if you wanted to make a folder with like 5 folders, each named something else in one command you could do:

sudo mkdir /hi/{1..3}

and it would make 3 folders, 1, 2, and 3 inside the hi folder, is it possible to do this in lua/computercraft?

Not that I'm aware of. You could certainly write a program that does it, but the support is not there in CraftOS.

Although, in Lua, this is so simple that it might as well be a single command:

for i = 1, 3 do fs.makeDir("/hi/" .. i) end

Note that "hi" doesn't have to exist first.

Using fs.open() to create write-mode file handles will also create any necessary directories within the specified paths, if they're not already present.
