Feedback

From time to time I pick up new small but powerful features in PowerShell, here is a handy one:
Did you know you can use wildcards in combination with tab-completion? Both with verbs and nouns? A few examples:
rec*-j* <tab> resolves to Receive-Job
set-*quick* <tab> resolves to Set-WSManQuickConfig
*-*computer*<tab> resolves to Add-Computer. Cycle through <tab> several times and you can see all cmdlets with “computer” in it`s noun.
Handy when you remember just parts of the cmdlet-name, typing a hard-to-spell cmdlet name…or even just being lazy
