With last week's release - there was also an updated version on PowerCLI that was released as well.

VMware vSphere PowerCLI 5.5 Release 1 Release Notes

I noticed something quite strange (personally I have not yet hit this bug - but I am sure it must have happened to someone)

That sounds like fun… :)

So I put a question up on the the PowerCLI community.

What exactly does this mean?
Will it run the first 2?
Last 2?
Even lines?
Odd lines?
Just choose which some random lines?

I received the answer from Dimitar and thought that it would be worthwhile to share it with you all.

What this means is that it will either run the whole script or just the first line. We haven't been able to work out exactly what causes this, but we believe it has something to do with the way we escape special symbols and redirect the output in the script before sending it to the guest OS.

This is not a new issue for this release, but we decided to add it to the release notes. There are a couple of workarounds for this
1) make the script single line
2) save the script in a .bat file, upload it to the guest using Copy-VMGuestFile and execute the file using Invoke-VMScript.

Something you might want to remember…
