You could update the console title bar inside your prompt function, but then the title bar would only get updated each time you press ENTER. Also, the prompt function may be overridden from other code.</p> <p>A better way is to spawn another PowerShell thread and let it update the title bar text, preserving whatever has been written to the title bar and just adding the information you want, for example the current time (or, for that matter, the current battery load or CPU load, RSS feed or whatever you want to have an eye on).</p> <p>Here's the code. Be aware that this will only work inside a real PowerShell console, not inside the ISE editor. After you run this code, call Add-Clock to add the current time to your console title bar.</p> <pre><span style="color:#0000ff;">function</span><span style="color:#000000;"> </span><span

is a cool little tool called whoami.exe which is part of Windows ever since Windows Vista. Since it can provide results not just in plain text but also as comma separated values, it is very easy to integrate into PowerShell. For example, to find out the groups your user account is member of, try this simple line:</p> <pre><span style="color:#0000ff;">PS</span><span style="color:#000000;">></span><span

is loading .NET assemblies. These assemblies can be precompiled using the tool ngen.exe which improves loading times (because the DLLs no longer have to be compiled each time they are loaded).</p> <p>Before you think about optimizing the DLLs PowerShell uses, you should do some reading on ngen.exe and its benefits. Then, you could use the following code to optimize all DLLs loaded by PowerShell.

In PowerShell, the same can be achieved by using the try/catch construct. You just need to know some little tricks. Take a look at this:</p> <pre><span style="color:#0000ff;">try</span><span style="color:#000000;"> { </span><span style="color:#000080;">$ErrorActionPreference</span><span style="color:#ff0000;">=</span><span style="color:#800000;">'</span><span style="color:#800000;">Stop</span><span style="color:#800000;">'</span><span style="color:#000000;"> </span><span style="color:#008000;"># commands follow </span><span style="color:#000000;">} </span><span style="color:#0000ff;">catch</span><span style="color:#000000;"> {} </span> </pre> <p>Now, if you want to execute a group of command and abort everything once an error occurs, simply place the commands inside the try block. If the commands are native console commands, add a "2>&1" to each command.</p> <pre><span style="color:#0000ff;">try</span><span style="color:#000000;"> { </span><span style="color:#000080;">$ErrorActionPreference</span><span style="color:#ff0000;">=</span><span style="color:#800000;">'</span><span style="color:#800000;">Stop</span><span style="color:#800000;">'</span><span style="color:#000000;"> </span><span style="color:#0000ff;">net</span><span style="color:#000000;"> </span><span style="color:#0000ff;">user</span><span style="color:#000000;"> </span><span style="color:#0000ff;">nonexistent</span><span style="color:#000000;"> </span><span style="color:#000000;">2</span><span style="color:#000000;">>&</span><span style="color:#000000;">1</span><span style="color:#000000;"> </span><span style="color:#008000;"># this raises an error </span><span style="color:#000000;"> </span><span style="color:#0000ff;">ipconfig</span><span style="color:#000000;"> </span><span style="color:#000000;">2</span><span style="color:#000000;">>&</span><span style="color:#000000;">1</span><span style="color:#000000;"> </span><span style="color:#008000;"># this will not execute due to the previous error </span><span style="color:#000000;">} </span><span style="color:#0000ff;">catch</span><span style="color:#000000;"> {} </span> </pre> <p>Try and replace "nonexistent " with an existing local user account such as "Administrator", and you'll see that ipconfig will execute.</p> <p><a target="twitter" href="http://twitter.com/home/?status=RT+%40PowerTip+%20Executing%20Commands%20in%20Groups%20with%20%23PowerShell+http://bit.ly/Jk7162"><img src="http://powershell.com/cs/Themes/powershell/images/ps/twitter_32x32.png" alt="Twitter This Tip!" style="vertical-align:middle;border:0px;" /></a> <a target="twitter" href="http://twitter.com/home/?status=RT+%40%20Executing%20Commands%20in%20Groups%20with%20%23PowerShell+http://bit.ly/Jk7162">ReTweet this Tip!</a></p><div style="clear:both;"></div><img src="http://powershell.com/cs/aggbug.aspx?PostID=16474" width="1" height="1">Listing All WMI Namespaceshttp://powershell.com/cs/blogs/tips/archive/2012/05/14/listing-all-wmi-namespaces.aspxMon, 14 May 2012 11:00:00 GMTf421715f-7aba-45f0-8a8d-44de5318a3a7:16473ps10http://powershell.com/cs/blogs/tips/rsscomments.aspx?PostID=16473http://powershell.com/cs/blogs/tips/archive/2012/05/14/listing-all-wmi-namespaces.aspx#comments<p>WMI is organized into namespaces which work similar to subfolders.
