Don't parse ls, it's evil! Use find with zero-terminated strings instead (on linux):

function scandir(directory)
    local i, t = 0, {}
    local pfile = assert(io.popen(("find '%s' -maxdepth 1 -print0"):format(directory), 'r'))
    local list = pfile:read('*a')
    pfile:close()
    for filename in s:gmatch('[^\0]+')
        i = i + 1
        t[i] = filename
    end
    return t
end

WARNING: however, as an acceped answer this apporach could be exploited if directory name contain ' in it. Only one safe solution is to use lfs or other special library.
