From the help: Code: lua -e'a=1' -e 'print(a)' script.lua "... does not compute." from an old sf movie. But seriously, I can't get the simplest of snippets to work from the command line or @Lua Running a file does seem to work, but anything quoted is ... unwieldy. >lua -e print("Hello world") surprisingly also works, although I would think the quoting is wrong. So, would you be so kind to explain how I'm supposed to quote a Lua line like; Code: print(string.gsub("hello world", "(%w+)", "%1 %1")) Regards, Dirk Jan Spits.
