What I got from a typo with the Cisco show command.

While working on another article dealing with telnet and SSH.  I ran across a command I never used or seen before.   Originally I wanted see the configuration for line console and typed out “show run line console 0” but instead, for some reason or another I hit the enter key after I typed “sho run line” and saw this.
