Can't run /usr/bin/demo from lua script file
lua version = 5.3.4.
I want to run os.execute(/usr/bin/demo &)
in lua,it will occur attempt to call a nil value (field 'execute')
But when I am in Lua interactive mode, it is normal to execute os.execute("/usr/bin/demo &").
1.Does the Lua script have no permission to execute shell instructions? Or is there any other better way to execute shell instructions?
