copied!<p>EDIT - As it turns out, this was fixed in Fabric 1.4.4. From the changelog:</p> <blockquote> <p>[Feature] <a href="https://github.com/fabric/fabric/issues/725">#725</a>: Updated local to allow override of which local shell is used. Thanks to Mustafa Khattab.</p> </blockquote> <p>So the original question would be fixed like this:</p> <pre><code>def test(): local('c', shell='/bin/bash') </code></pre> <p>I've left my original answer below, which only relates to Fabric version < 1.4.4.</p> <hr> <p>Because local doesn't use bash. You can see it clearly in your output</p> <pre><code>/bin/sh: c: command not found </code></pre> <p>See? It's using <code>/bin/sh</code> instead of <code>/bin/bash</code>. This is because Fabric's <code>local</code> command behaves a little differently internally than <code>run</code>. The <code>local</code> command is essentially a wrapper around the <code>subprocess.Popen</code> python class.</p> <p><a href="http://docs.python.org/library/subprocess.html#popen-constuctor">http://docs.python.org/library/subprocess.html#popen-constuctor</a></p> <p>And here's your problem. Popen defaults to <code>/bin/sh</code>. It's possible to specify a different shell if you are calling the Popen constructor yourself, but you're using it through Fabric. And unfortunately for you, Fabric gives you no means to pass in a shell, like <code>/bin/bash</code>.</p> <p>Sorry that doesn't offer you a solution, but it should answer your question.</p> <p>EDIT</p> <p>Here is the code in question, pulled directly from fabric's <code>local</code> function defined in the <code>operations.py</code> file:</p> <pre><code>p = subprocess.Popen(cmd_arg, shell=True, stdout=out_stream, stderr=err_stream) (stdout, stderr) = p.communicate() </code></pre> <p>As you can see, it does NOT pass in anything for the executable keyword. This causes it to use the default, which is /bin/sh. If it used bash, it'd look like this:</p> <pre><code>p = subprocess.Popen(cmd_arg, shell=True, stdout=out_stream, stderr=err_stream, executable="/bin/bash") (stdout, stderr) = p.communicate() </code></pre> <p>But it doesn't. Which is why they say the following in the documentation for local:</p> <blockquote> <p>local is simply a convenience wrapper around the use of the builtin Python subprocess module with shell=True activated. If you need to do anything special, consider using the subprocess module directly.</p> </blockquote>
