PowerShell is largely based on the syntax of the ksh shell, so most
constructs that work in ksh will work in PS as well.
In this case:
$FOO=(hostname)
That will interpolate anywhere, not just during variable assignment, so
you can do stuff like:
Some-CmdLet -Host (hostname)
If you're familiar with the use of backticks in bash the mechanism is
exactly the same, just different syntax.

Nice one, I'll give that a go. You don't happen to know how I can set
a variable to equal the result of a powershell command do you? I need
to use the hostname of the machine as a parameter for another command.
At the minute I'm using hard-coding which is obviously a cardinal sin.

We solve this issue by doing (kind of ugly) stuff like this in our
modules:
unless => 'if ( ! ( Get-Service mcollectived ) ) { exit 1 }',
If you don't like that syntax, you may be able to use the $? or
$LastExitCode variables that get set by PowerShell (I haven't
tested this, however). Both of those have non-obvious gotchas. A
good writeup on error handling in PS (not Puppet-specific) is
here:

Hi Guys,
So I've been working with puppet on windows and I think my
approach is all wrong. I've been using the puppetlabs/powershell
module to run commands, however I'm having difficulty with exit
codes. Primarily puppet expects exit codes to denote
success/failure, whereas powershell is returning objects (and
giving a 0 exit code regardless of result).
I'm automating the install of old bits of software, so getting
meaningful answers out of the installers is pretty difficult,
this means that the scripts are a bit ugly and not very
idempotent. Typically I have to check a log file to find out if
the install actually worked.
Are there any examples out there of windows puppet automation
that makes heavy use of the powershell module?
Cheers,
Tom
