int Readline::Execute	(	const std::string &	fname,
		const std::map< std::string, std::string > &	args = std::map<std::string,std::string>()
	)

Executes commands read from an ascii file as they were typed in the console. Empty lines and lines beginning with # are ignored.

Parameters

fname	Filename of file to read
args	Arguments to be passed to the script. A search and replace will be done for ${arg}

Returns

-1 if the file couldn't be read and the number of commands for which Process() was callled otherwise
