Using Previledge mode commands in Global Config Mode

I think it is very useful tip when using the show, ping, and telnet commands. Instead of switching back and forth between global configuration mode and privilege mode to use these commands, you can remain in global configuration mode and type the do command with the original syntax.

For example:

Router(config)#do show running-config

or

Router(config)#do show interface s0

or

Router(config)#do PING 20.0.0.1
