| 16 | When creating recipes using Bash and inserting code that handles build | ||
| 17 | logs you have the same goals - informative with minimal console output. | ||
| 18 | The syntax you use for recipes written in Bash is similar to that of | ||
| 19 | recipes written in Python described in the previous section. | ||
| 20 | </p> | ||
| 21 | <p> | ||
| 22 | Following is an example written in Bash. | ||
| 23 | The code logs the progress of the <code class="filename">do_my_function</code> function. | ||
| 24 | </p> | ||
| 25 | <pre class="literallayout"> | ||
| 26 | do_my_function() { | ||
