186 Chapter 4 � Configuration and IOS Management Commands
To find commands that start with a certain letter, use the letter and the
question mark (?) with no space between them.
Router#c?
clear clock configure connect copy
Router#c
Notice that by typing “c?”, we received a response of all the commands
that start with “c”. Also notice that the Router# prompt appeared with our
command still present. This is helpful when you have long commands and
need the next possible command. Think about how tiresome it would be if
you had to retype the entire command every time you used a question mark!
To find the next command in a string, type the first command and then a
question mark.
Router#clock ?
set Set the time and date
Router#clock set ?
hh:mm:ss Current Time
Router#clock set 10:30:10 ?
Day of the month
MONTH Month of the year
Router#clock set 10:30:10 28 ?
MONTH Month of the year
Router#clock set 10:30:10 28 may ?
Year
Router#clock set 10:30:10 28 may 2000 ?
Router#
By typing the command clock, then a space and a question mark, you
will get a list of the next possible commands and what they do. Notice that
you should just keep typing a command, a space, and then a question mark
until (carriage return) is your only option.
