Along with compilation from within EiffelStudio, it is possible to start compilation from a command line (shell). This is useful in particular to recompile your system automatically as part of a script.

To use the command-line compiler -- <code> ec </code> for Eiffel Compilation -- execute 
<code>
	ec option & [class_name] [feature_name]
		</code>

Specify <code> class_name </code> and <code> feature_name </code> only if you wish to produce information about a class or a feature. Otherwise <code> ec </code> will compile a system according to each specified <code> option </code>. [[EiffelStudio: Command line options|Click here to see the set of supported options.]]
