Chapter 2 Using the Command-Line Interface
Using Editing Features
Editing Command Lines that Wrap
You can use a wraparound feature for commands that extend beyond a single line on the screen. When
the cursor reaches the right margin, the command line shifts ten spaces to the left. You cannot see the
first ten characters of the line, but you can scroll back and check the syntax at the beginning of the
command. The keystroke actions are optional.
To scroll back to the beginning of the command entry, press
Ctrl-B
or the left arrow key repeatedly. You
can also press
Ctrl-A
to immediately move to the beginning of the line.
The arrow keys function only on ANSI-compatible terminals such as VT100s.
In this example, the
access-list
global configuration command entry extends beyond one line. When the
cursor first reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. The dollar
sign ($) shows that the line has been scrolled to the left. Each time the cursor reaches the end of the line,
the line is again shifted ten spaces to the left.
Switch(config)#
access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1
Switch(config)# $
101 permit tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.25
Switch(config)# $
t tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq
Switch(config)# $
108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq 45
After you complete the entry, press
Ctrl-A
to check the complete syntax before pressing the
Return
key
to execute the command. The dollar sign ($) appears at the end of the line to show that the line has been
scrolled to the right:
Switch(config)#
access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1$
