<h1 class="chapter">Writing Recipes in Rules</h1> <p>The recipe of a rule consists of one or more shell command lines to be executed, one at a time, in the order they appear. Typically, the result of executing these commands is that the target of the rule is brought up to date. </p> <p>Users use many different shell programs, but recipes in makefiles are always interpreted by <samp>/bin/sh</samp> unless the makefile specifies otherwise. See <a href="execution">Recipe Execution</a>. </p> <table class="menu" border="0" cellspacing="0"> <tr>
