Windows::Management

Find how long since you last restarted:

systeminfo | find "Up Time"

Network::Cisco::IOS

I often want to look at how ports are configured on a switch, the descr, what vlan, etc.
"show run | include" type commands don't really help because the port config is on multiple lines.

The following are very useful, if only I could remember them:

show int status
show int summary
