Try:

     ($env:Path).Replace(&#39;;&#39;,&quot;`n&quot;)

or

    $env:path.split(&quot;;&quot;)

Fewer keystrokes using either the split **operator** or **method**

    $env:Path -split &#39;;&#39;
    $env:Path.split(&#39;;&#39;)

this works for me (in a cmd window):

    powershell -Command ($env:Path).split(&#39;;&#39;)

I currently have a repository for just about every table in the database and would like to further align myself with DDD by reducing them to aggregate roots only.

Let’s assume that I have the following tables, `User` and `Phone`.  Each user might have one or more phones.  Without the notion of aggregate root I might do something like this:

	//assuming I have the userId in session for example and I want to update a phone number
	List&lt;Phone&gt; phones = PhoneRepository.GetPhoneNumberByUserId(userId);
	phones[0].Number = “911”;
	PhoneRepository.Update(phones[0]);

The concept of aggregate roots is easier to understand on paper than in practice.  I will never have phone numbers that do not belong to a User, so would it make sense to do away with the PhoneRepository and incorporate phone related methods into the UserRepository?  Assuming the answer is yes, I’m going to rewrite the prior code sample.

Am I allowed to have a method on the UserRepository that returns phone numbers? Or should it always return a reference to a User, and then traverse the relationship through the User to get to the phone numbers:

	List&lt;Phone&gt; phones = UserRepository.GetPhoneNumbers(userId);
	// Or
	User user = UserRepository.GetUserWithPhoneNumbers(userId); //this method will join to Phone

Regardless of which way I acquire the phones, assuming I modified one of them, how do I go about updating them?  My limited understanding is that objects under the root should be updated through the root, which would steer me towards choice #1 below.  Although this will work perfectly well with Entity Framework, this seems extremely un-descriptive, because reading the code I have no idea what I’m actually updating, even though Entity Framework is keeping tab on changed objects within the graph.

	UserRepository.Update(user);
	// Or
	UserRepository.UpdatePhone(phone);

Lastly, assuming I have several lookup tables that are not really tied to anything, such as `CountryCodes`, `ColorsCodes`, `SomethingElseCodes`.  I might use them to populate drop downs or for whatever other reason.  Are these standalone repositories?  Can they be combined into some sort of logical grouping/repository such as `CodesRepository`?  Or is that against best practices.


Reducing Repositories to Aggregate Roots

Having this basic function

    protected ModelAndView handleRequestInternal(...) {
        ...
        return new ModelAndView(&quot;welcomePage&quot;, &quot;WelcomeMessage&quot;, message);
    }

I know that this will return modelandView. 
I know that `welcomePage` is my viewname so that means something like `welcomepage.jsp` will get called.

But I am confused with what is Model part. 
What is `WelcomeMessage` and `message` and how Model work in that scenario?

Using the windows command prompt, can I echo %path% and get the resulting paths on separate rows?
Something like this but for windows: 

    echo $path | tr &#39;:&#39; &#39;\n&#39;

Can I do this with vanilla cmd or do I need powershell or js scripting?

Example echo %path% output:

How can I write a variable to the console without a space after it? There are problems when I try:

Let&#39;s say we have an array of objects $objects. Let&#39;s say these objects have a &quot;Name&quot; property.

This is what I want to do 

     $results = @()
     $objects | %{ $results += $_.Name }

This works, but can it be done in a better way?

If I do something like: 

     $results = objects | select Name
 
`$results` is an array of objects having a Name property. I want $results to contain an array of Names.

Is there a better way?

I have a powershell script (`setup.ps1`), that we use as the entry point for our development environment setup scripts.  It takes a parameter:

        [Alias(&quot;t&quot;)]
        [string[]]

So I installed the android sdk for Windows:

http://developer.android.com/sdk/index.html   (the installation link) 

And ran into the path variable problem. So I fixed that by changing &quot;PATH&quot; in enviroment variables to include where my java.exe file is located from the JDK.  

But now when I open the android sdk manager, a cmd-like screen just briefly flashes on for half a second then disappears. I have no idea what&#39;s going on and how to get this thing working.

I am getting the following error from Apache

**[Sat Mar 19 23:10:50 2011] [warn] mod_fcgid: stderr: PHP Fatal error:  require_once() [&lt;a href=&#39;function.require&#39;&gt;function.require&lt;/a&gt;]: Failed opening required &#39;/common/configs/config_templates.inc.php&#39; (include_path=&#39;.:/usr/share/pear:/usr/share/php&#39;) in /home/viapics1/public_html/common/configs/config.inc.php on line 158**

I am definately not an expert of Apache but the file config.inc.php &amp; config_templates.inc.php are there. I also tried navigating to a test.html page I placed in common/configs/ so I assume there is no rights issues going on. I also set the rights on config_templates.inc.php to give everyone read, write, and execute rights. Not sure what to do at this point, I checked to see if there was a /usr/share/php directory and I found there was not but when I did yum install php it said it had the latest. Ideas? 


PHP Fatal Error Failed opening required File

I want to run a simple one-liner in the Windows CMD prompt to print my `%PATH%` variable, one entry per line.

I tried this: `for /f &quot;delims=;&quot; %a in (&quot;%path%&quot;) do echo %a` but this only prints the first entry:

    Z:\&gt;for /f &quot;delims=;&quot; %a in (&quot;%path%&quot;) do echo %a

    Z:\&gt;echo c:\python25\.
    c:\python25\.

Also as you can see from the output above, this is also printing the `echo %a` command as well as the output. Is there any way to stop this?

If I try a similar command, I get all the entries, but still get the `echo %a` output spamming the results. I don&#39;t understand why the following prints all entries, but my attempt on `%PATH%` doesn&#39;t. I suspect I don&#39;t understand the `/F` switch.

    Z:\&gt;for %a in (1 2 3) do echo %a

    Z:\&gt;echo 1

How to count no of lines in text file and store the value into a variable using batch script?

I have to set environment variables on different windows machines, but I don&#39;t want to be bothered changing them manually by getting on the properties screen of &quot;My Computer&quot;

I want to do it from the command line, with a batch file. As far as I understand, using set will only change the variable for the processes I will call in the command window.

I want to set it definitely, so later, when running a new process, it will use those new settings I have set. Is there a way to do that from the command line ?



Set a persistent environment variable from cmd.exe

I have a batch script that I use to launch a program, such as `notepad.exe`. When I double click on this batch file, notepad starts normally, but the black window of the `cmd` who launched `notepad.exe` remains in the background. What do I have to do in order to launch `notepad.exe` and make the cmd window disappear?

**edit**:  is more complicated than using `\I`.

The `cmd` calls `cygwin`, and `cygwin` starts `notepad`. I use 

`start \I \path\cygwin\bin\bash.exe`

and the first window (cmd) disappears, but a second window (\cygwin\bin\bash.exe) is still on the background. In the cygwin script I used `notepad.exe &amp;` and then exit.
