Chatroom Buzz:

  • so can we set up events on things like usb pen plugged in ?

  • Can I use ActiveScript consumer to wrap PowerShell in VBScript? Is that impelemented..?

  • can we reuse filters? i mean, can we use the same filter for multiple bindings?

  • when can we see a functional command-line consumer?

  • new subject. ASk him about his guest blog for HSg next week. something about dynamic method invocation

When are you going to integrate the module with PowerGUI?

  • or may be a nice GUI to list and bind filters/consumers..!

** 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* resolves to Receive-Job*

set-quick resolves to Set-WSManQuickConfig

*-computer resolves to Add-Computer. Cycle through 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 *
