Using the Command-Line Interface
How to Use the CLI to Configure 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 ($) appears at the end of the line to show that the line has been scrolled to the right:
Switch(config)# access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1$
The software assumes you have a terminal screen that is 80 columns wide. If you have a different width, use the terminal
width privileged EXEC command to set the width of your terminal.
Use line wrapping with the command history feature to recall and modify previous complex command entries. For
information about recalling previous command entries, see
Editing Commands Through Keystrokes, page 14 .
Designate a particular keystroke as
an executable command, perhaps as
a shortcut. Press Ctrl-V or Esc Q .
Scroll down a line or screen on
displays that are longer than the
terminal screen can display.
Note: The More prompt is used for
any output that has more lines than
can be displayed on the terminal
screen, including
show command
output. You can use the Return and
Space bar keystrokes whenever you
see the More prompt.
Press the Return key. Scroll down one line.
Press the Space bar. Scroll down one screen.
Redisplay the current command line
if the switch suddenly sends a
message to your screen. Press Ctrl-L or Ctrl-R. Redisplay the current command line.
