Lua Directory Wiper

[blindsighterr]

I originally wanted to make a script that would wipe folders with "Sensitive" content in them, but I ended up just making a full directory wiper.

This script deletes anything under the directory the file is placed and ran in.

All the code, because it's so small

require "lfs"
local curDir = lfs.currentdir()
local b = [[\]]
local function checkValidDir(dir) if dir == "." or dir == ".." or dir == "main.lua" then return false else return true end end
local function scanDir(dir)
	for fl in lfs.dir(dir) do
		if checkValidDir(fl) == true then
			if lfs.attributes(dir..b..fl, "mode") == "directory" then
				scanDir(dir..b..fl)
				lfs.rmdir(dir..b..fl)
			else
				os.remove(dir..b..fl)
			end
		end
	end
end
scanDir(curDir)

Thoughts?

This can be shortened to
[lua]local function checkValidDir(dir) return dir ~= "." and dir ~= ".." and dir ~= "main.lua" end[/lua]

[lua]if checkValidDir(fl) == true[/lua]
This can be shortened to
[lua]if checkValidDir(fl)[/lua]

Cool! I thought if func() then just checked if it was valid, not if it were true. Thanks!

scanDir(dir..b..fl)
lfs.rmdir(dir..b..fl)
else
os.remove(dir..b..fl)
end
end
end
end
scanDir(curDir)

It actually checks if it's either [B]false[/B] or [B]nil[/B]. Unless you need to explicitly know exactly what it is, you should always use it in the way I just showed you. Makes life easier. It's not limited to function calls, you can use it in, for example, if statements.
[lua]local whatever = 1

if (whatever)
-- whatever is not false or nil so this would be ran
end[/lua]
