Command-Line Editing; History Substitution - Cisco WS-C4003 - Catalyst 4000 Chassis Switch Software Configuration Manual

Chapter 2 Using the Command-Line Interface
To use the partial-keyword-lookup function, enter ? to display a list of commands that begin with a
specific set of characters. Do not insert a space between the last letter of the variable and the question
mark (?). For example, enter co? at the privileged prompt to display a list of commands that start with
co. The system displays all commands that begin with co as follows:
Console> (enable) co?
configure
copy
Console> (enable) co
The system repeats the command you entered without the question mark (?).
