You can use the backtick operator:

<pre><code>&amp; "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" `
 -verb:sync `
 -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" `
 -dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"
</code></pre>

That's still a little too long for my taste, so I'd use some well-named variables:

<pre><code>$msdeployPath = "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe"
$verbArg = '-verb:sync'
$sourceArg = '-source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web"'
$destArg = '-dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"'

&amp; $msdeployPath $verbArg $sourceArg $destArg
</code></pre>

Another method for cleaner argument passing would be <a href="http://technet.microsoft.com/en-us/magazine/gg675931.aspx" rel="noreferrer" title="Windows PowerShell: Splatting">splatting</a>.

Define your parameters and values as a hashtable like this: 

<pre><code>$params = @{ 'class' = 'Win32_BIOS';
 'computername'='SERVER-R2';
 'filter'='drivetype=3';
 'credential'='Administrator' }
</code></pre>

And then call your commandlet like this:

<pre><code>Get-WmiObject @params
</code></pre>

blocks|key|1281598|text|另一种将字符串分成多行的方法是在字符串中间放置一个空表达式，并将其分成几行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1281599|示例字符串：|1281600|"stackoverflow+stackoverflow+stackoverflow+stackoverflow+stackoverflow"|offset|length|style|CODE|1281601|跨行中断：|1281602|"stackoverflow+stackoverflow+$(

Another way to break a string across multiple lines is to put an empty expression in the middle of the string, and break it across lines:

sample string:

<code>"stackoverflow stackoverflow stackoverflow stackoverflow stackoverflow"</code>

broken across lines:

<pre><code>"stackoverflow stackoverflow $(
)stackoverflow stack$(
)overflow stackoverflow"
</code></pre>

How do you take a command like the following in PowerShell and split it across multiple lines?

<pre><code>&amp;"C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -verb:sync -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" -dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"
</code></pre>
