Is there an official (ie. technet or MSDN, not a blog) reference for PowerShell literal (or generally reserved) characters/symbols?
Characters I’m referring to include | (piping data), $ (variables), @() (arrays), @{} (hashtables), and ${} (I don’t even know what this does)
I would start with
PS C:\> Get-Help About_Reserved_Wordsand the continue reading the referenced help pages.See Also:
The built-in help with PowerShell using
Get-Helpis one of the hidden gems.
