You're kind-of right – it's just the command line call that normally 
starts processing. (i.e. one uses lualatex filename.tex)

With the call

luatex --help

on the command line, LuaTeX prints all the command line arguments it 
knows, e.g. the two shell-escape switches:

    --[no-]shell-escape           disable/enable \write18{SHELL COMMAND}
    --shell-restricted            restrict \write18 to a list of 
commands given in texmf.cnf

But in this list I cannot find a switch that activates shell escape on a 
file basis. Or do you mean the --shell-restricted?
