How to create a directory in Lua?

Question

Is it possible to create a directory in lua ? If so, how ?

Answer 1

There's a "system" call (or something like that, this is from memory) which you should be able to use to run an arbitrary program, which could include the mkdir command.

EDIT: I found my Programming in Lua book. On page 203, it mentions how you could use an

os.execute("mkdir " .. dirname)

to "fake" a directory creation command.

EDIT 2: Take note of Jonas Thiem's warning that this command can be abused if the directory name comes from an untrusted source!
