AFAIK, you cannot directly pass args from the command line to Wireshark Lua, but an easy alternative would be to use environment variables. Set an environment variable and query it from your script, using os.getenv <http://www.lua.org/manual/5.1/manual.html#pdf-os.getenv> . 

Here's an example from OSX:

$ echo "print('TESTVAR', os.getenv('TESTVAR'))" > test.lua
$ TESTVAR="hello world" tshark -v -Xlua_script:test.lua 
TESTVAR hello world
