interactive lua: command line arguments
If you run file.lua in cmd of freeswitch
freeswitch> luarun prog.lua arg1
You can use prog.lua:
#print(argv[1])
And run: $lua prog.lua arg1
(run in script folder)
You can use prong.lua:
#print(arg[1])
You're missing the arg
vector, which has the elements you want in arg[1]
, arg[2]
, and so on:
% lua -i -- /dev/null one two three

Lua stores arguments in a table. This table is the "arg" table. You can access the passed arguments inside using arg[1], arg[2], ...
arg[0] is the name of the lua program. arg[1] is the first argument passed, arg[2] is the second argument passed and so on...
In addition to the arg
table, ...
contains the arguments (arg[1] and up) used to invoke the script.
