How to split long commands over multiple lines in PowerShell
Another method for cleaner argument passing would be splatting.
Define your parameters and values as a hashtable like this:
$params = @{ 'class' = 'Win32_BIOS';
'computername'='SERVER-R2';
'filter'='drivetype=3';
'credential'='Administrator' }
And then call your commandlet like this:
Get-WmiObject @params

Looks like it works with Powershell 2.0 and up
Ah, and if you have a very long string that you want to break up, say of HTML, you can do it by putting a @
on each side of the outer "
- like this:
$mystring = @"
Bob
went
to town
to buy
a fat
pig.
"@
You get exactly this:
Bob
went
to town
to buy
a fat
pig.
And if you are using Notepad++, it will even highlight correctly as a string block.
Now, if you wanted that string to contain double quotes, too, just add them in, like this:
$myvar = "Site"
$mystring = @"
<a href="http://somewhere.com/somelocation">
Bob's $myvar
</a>
"@
You would get exactly this:
<a href="http://somewhere.com/somelocation">
Bob's Site
</a>
However, if you use double-quotes in that @-string like that, Notepad++ doesn't realize that and will switch out the syntax colouring as if it were not quoted or quoted, depending on the case.
And what's better is this: anywhere you insert a $variable, it DOES get interpreted! (If you need the dollar sign in the text, you escape it with a tick mark like this: ``$not-a-variable`.)
NOTICE! If you don't put the final "@
at the very start of the line, it will fail. It took me an hour to figure out that I could not indent that in my code!
Here is MSDN on the subject: Using Windows PowerShell “Here-Strings”
Trailing backtick character, i.e.,
&"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"
White space matters. The required format is Space`Enter.
