Re: Pass command line arguments to a LUA script?

[Tony Trinh <tony19 () gmail com>]

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
