Searching and Filtering Output of show and more Commands Chapter 5 Using the Command-Line Interface 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. ap(config)# access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1 ap(config)# $ 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.25 ap(config)# $t tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq ap(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: ap(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 command entries. For information about recalling previous command entries, see the "Editing Commands through Keystrokes" section on page 5-6. 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. 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 are displayed. This example shows how to include in the output display only lines where the expression protocol appears: ap# 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 Cisco Aironet 1100 Series Access Point Hardware Installation Guide 5-8 OL-4309-02

Chapter 5

Using the Command-Line Interface

Searching and Filtering Output of show and more Commands

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.

ap(config)#

access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1

ap(config)# $

101 permit tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.25

ap(config)# $

t tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq

ap(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:

ap(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 command

entries. For information about recalling previous command entries, see the

“

Editing Commands through

Keystrokes

”

section on page 5-6

Searching and Filtering Output of show and more Commands

You can search and filter the output for

show

and

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.

To use this functionality, enter a

show

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

are displayed.

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

protocol

appears:

ap#

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
