'PowerShell String Formatting: Why is the colon character causing my variable's value to be blank?
I was looking over what's coming with the next WinRM and PowerShell 3 and I was looking through the list of breaking changes and saw something that I'd never seen before.
The example was:
$server = "msp42"
$status = "online"
"$server: $status"
The resulting output was:
online
OK, I'd never encountered that before and have no clue why the colon caused an issue. A solution suggested in the document was to put a space (which is silly because then you change the output):
"$server : $status"
Another suggestion was to use this format (new to me!):
"${server}: $status"
The final suggestion was to make an expression, which I am familiar with and use all the time:
"$($server): $status"
So, my questions to you PowerShell gurus out there are:
What the heck is up with that colon? Does it do something?
What the heck is the
${variable}syntax? Is it strictly to deal with the colon or does it have some neat features?
