lua通过命令行传参数

lua test.lua abc 123

--test.lua
local params = {...}
print(#params)
print(params[1])
print(params[2])

测试一下：

~# lua test.lua abc 123
2
abc
123

参考：https://stackoverflow.com/questions/9778186/how-can-i-pass-the-arguments-to-the-lua-file-through-the-lua-cli

local params = {...}
params[1] -- first parameter, if any.
params[2] -- second parameter, if any.
#params   -- number of parameters.
