Executing external program with PowerShell

I need a PowerShell script to (among other things) execute commands (contained in script.txt) on a remote system.  The following works if I put it in a Windows command file (.cmd).  

C:\PuTTY\plink.exe 10.10.10.5 -ssh -P 1234 -l username -pw xyz < %temp%\script.txt

How can I do this inline in PoweShell?  I expect I'll need to use the invoke-expression comdlet, but can't figure out how to handle the parameters and input redirection.

Try this:

$arg1 = "10.10.10.5"
$arg2 = "-ssh"
$arg3 = "-P"
$arg4 = "1234"
$arg5 = "-l"
$arg6="username"
$arg7="-pw"
$arg8 = "xyz"
$arg9="< %temp%\script.txt"

$args = @($arg1,$arg2,$arg3,$arg4,$arg5,$arg6,$arg7,$arg8,$arg9)

 & "C:\PuTTY\plink.exe"  $args

That's a pretty awful way to supply arguments. And it won't work, in particular the input redirection.
You should not need to do anything special here. The only change needed is to replace %temp% with $env:Temp
C:\PuTTY\plink.exe 10.10.10.5 -ssh -P 1234 -l username -pw xyz < $env:Temp\script.txt

Open in new window

or, more Powershell'ish:
Get-Content $env:Temp\script.txt | C:\PuTTY\plink.exe 10.10.10.5 -ssh -P 1234 -l username -pw xyz

Open in new window
