PowerShell is Microsoft's shell for their product lines. It's now on version 3.0. If you miss the power of the command line while using Windows on either your laptop or servers, PowerShell provides that power.
Important concepts: Almost all aspects of the Microsoft ecosystem are objects within an overarching structure. You query and manipulate this structure and its objects with PowerShell. This includes all aspects of SharePoint, Active Directory, and Exchange. Other companies, like VMware (see below) have also written PowerShell modules.This "object nature" means that PowerShell pipes pass objects and properties, not just text. Variables store data-structures of objects.
Note: Unwrap the code lines before you use them.
Get the usage of the command "Select-Object":
Built-in examples for the command "Select-Object":
returns: ssh_rsa_verify: RSA modulus too small: 512 < minimum 768 bits
key_verify failed for server_host_key
The modulus of the ssh RSA key pair on the switch is too small. If you have access, generate a new key pair on the switch with a larger modulus.
ProcedureLogin with ssh protocol version 1 (ssh space dash one): ssh -1 user@cisco_switch(On the switch): enable(On the switch): Authenticate to "Privileged Exec Mode" mode on the switch.(On the switch): conf t(On the switch): crypto key generate rsa general-keys modulus 1024(On the switch): Press enter to accept that the current key pair for the switch will be replaced.
You now should be able to log into the switch with ssh protocol version 2.
The article describes how to open video, audio, and other media files in the Raspberry Pi desktop (the LXDE file manager) using the GPU-based player program.
Does double-clicking on a video file in Raspbian result in slow blocky playback in SMPlayer and VLC on your Raspberry Pi?
The short answer is that those video players will not work because at this time (Nov. 2013), they do not make use of the GPU on the Raspberry Pi. You need to use the hardware accelerated player, omxplayer, that is used in XBMC Live and OpenELEC. The problem is that omxplayer is a command line player that is designed to be embedded in the XBMC based distributions. I present below a way to make it play videos, if you double-click them in the Raspbian Desktop. Others have presented this method, but I've added a little bit of abstraction to make management easier. To start, open LXTerminal and the follow the process below.
Step One - Get rid of the CPU-based media players sudo aptitude remove vlc smplayer
