Searching and Filtering Output of show and more Commands

You can use a wraparound feature for commands that extend beyond a single line on the scre en . W hen

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.

Note 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. E ach time th e cu rsor reach es the end o f the lin e,

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 be fore pr essing the Return key

to execute the command. The dollar sign ($) appears at the end of the lin e to s how 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 width other than

that, 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 comm and

entries. For information about recalling previous command entries, see the “E dit ing Com mands throug h

Keystrokes” section on page2-6.

Searching and Filtering Output of show and more Commands

You can search and filter the output for show and more commands. This is useful when you need to sort

through large amounts of output or if you want to exclude output that you do not need to see. Using these

commands is optional.

To use this functionality, enter a show or more command followed by the pipe character (|), one of the

keywords begin, include, or exclude, and an expression that you want to search for or filter out:

command | {begin | include | exclude} regular-expression

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output

are not displayed, but the lines that contain Output appear.

This example shows how to include in the output display only lines where the expression protocol

appears:

Switch# show interfaces | include protocol

Vlan1 is up, line protocol is up

Vlan10 is up, line protocol is down

GigabitEthernet0/1 is up, line protocol is down

GigabitEthernet0/2 is up, line protocol is up
