Key Function
Tab
If you press
Tab
after entering part of a keyword, the system automatically
completes the keyword:
•
If finding a unique match, the system substitutes the complete keyword for the
incomplete one and displays it in the next line.
•
If there is more than one match, you can press
Tab
repeatedly to display in
cycles all the keywords starting with the character string that you typed.
•
If there is no match, the system does not modify the incomplete keyword and
displays it again in the next line.
Typing incomplete keywords
You can input a command comprising incomplete keywords that can uniquely identify the complete
command.
In user view, for example, commands starting with an
s
include
startup
saved-configuration
and
system-view
.
•
To enter system view, type
sy
.
•
To set the configuration file to be used at the next startup, type
st s
.
You can also press
Tab
to have an incomplete keyword automatically completed.
Configuring command aliases
The command alias function allows you to replace the first keyword of a command with your preferred
keyword. For example, if you configure
show
as the replacement for the
display
keyword, then to execute
the
display xx
command, you can input the command alias
show xx
.
Note the following guidelines when configuring command aliases:
•
When you input a command alias, the system displays and saves the command in its original
format instead of its alias. In other words, you can define and use a command alias but the
command is not restored in its alias format.
•
When you define a command alias, the
cmdkey
and
alias
arguments must be in their complete
form.
•
When you input an incomplete keyword that partially matches both a defined alias and the
keyword of a command and the command alias function is enabled, the alias wins. To execute the
command whose keyword partially matches your input, input the complete keyword. When you
input a character string that partially matches multiple aliases, the system gives you prompts.
•
If you press
Tab
after you input the keyword of an alias, the original format of the keyword is
displayed.
•
You can replace only the first keyword of a non-undo command instead of the complete command;
and you can replace only the second keyword of
undo
commands.
