    <p>I'm trying to take advantage of AWS Elastic Beanstalk's facility to customize the EC2 instances it creates. This requires creating a <a href="http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-windows-ec2.html" rel="nofollow noreferrer">.config file in the .ebextensions directory</a>.</p> <p>You can specify a number of commands which should be executed when the application is deployed to an instance. I'm using that to install some msi files, and also to configure EC2 to assign the instance a unique name. This then requires a reboot.</p> <p>My problem is that I only want these commands to be run when an instance is first deployed. When I deploy a code-only change to existing instances they shouldn't be run.</p> <p>I've tried using the "test" parameter, which should prevent the command running. I create a file as the last command, and then I check for the presence of that file in the "test" parameter. But it doesn't seem to work.</p> <p>My config file is like this:</p> <pre><code># File structure documented at http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-windows-ec2.html files: "C:\\Users\\Public\\EnableEc2SetComputerName.ps1": source: "[File Source]" commands: init-01-ec2setcomputername-enable: test: cmd /c "if exist C:\\Users\\Public\\initialised (exit 1) else (exit 0)" command: powershell.exe -ExecutionPolicy Bypass -File "C:\\Users\\Public\\EnableEc2SetComputerName.ps1" waitAfterCompletion: 0 init-05-reboot-instance: test: cmd /c "if exist C:\\Users\\Public\\initialised (exit 1) else (exit 0)" command: shutdown -r # restart to enable EC2 to set the computer name waitAfterCompletion: forever init-06-mark-initialised: test: cmd /c "if exist C:\\Users\\Public\\initialised (exit 1) else (exit 0)" command: echo initialised &gt; C:\\Users\\Public\\initialised waitAfterCompletion: 0 </code></pre> <p>Is there an alternative way to accomplish this? Or am I doing something stupid?</p> <p>On Unix-based systems, there are the <code>touch</code> and <code>test</code> commands (referred to in <a href="https://stackoverflow.com/a/16846429/1727">this answer</a> asking the equivalent question for Unix systems). What's the equivalent in Windows which will work best in this situation?</p>

    2. CO@JimFlanagan thanks for that, but your answer seems to be Unix-specific: I tried the approach you outlined, and it fails on Windows. I've updated my question to emphasise that this is Windows-specific.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
