Cisco Systems Cisco IOS XR Adding a Filter at the --More-- Prompt, File on the specified device

Chapter 6 CLI Tips, Techniques, and Shortcuts

Displaying System Information with show Commands

Table 6-3	show Command Filter Options
Command		Description
show command begin regular-expression		Begins unfiltered output of the show command with the first line that
		contains the regular expression.
show command exclude regular-expression		Displays output lines that do not contain the regular expression.
show command include regular-expression		Displays output lines that contain the regular expression.
show command file device0:path/file		Writes the output lines that contain the regular expression to the specified
		file on the specified device.

In the following example, the show interface command includes only lines in which the expression “protocol” appears:

RP/0/RP0/CPU0:router# show interface			include protocol
Null0 is up, line protocol is up
0	drops for unrecognized	upper-level	protocol
POS0/2/0/0 is administratively down,			line protocol	is administratively down
0	drops for unrecognized	upper-level	protocol
POS0/2/0/1 is administratively down,			line protocol	is administratively down
0	drops for unrecognized	upper-level	protocol
POS0/2/0/2 is administratively down,			line protocol	is administratively down
0	drops for unrecognized	upper-level	protocol
POS0/2/0/3 is administratively down,			line protocol	is administratively down
0	drops for unrecognized	upper-level	protocol
MgmtEthernet0/RP0/CPU0/0		is administratively down,		line protocol is administratively
down
MgmtEthernet0/RP0/CPU0/0		is administratively down,		line protocol is administratively
down
0	drops for unrecognized	upper-level	protocol

Note Filtering is available for submodes, complete commands, and anywhere that <cr> appears in the “?” output.

Adding a Filter at the --More-- Prompt

You can specify a filter at the --More--prompt of a show command output by entering a forward slash (/) followed by a regular expression. The filter remains active until the command output finishes or is interrupted (using Ctrl-Z or Ctrl-C). The following rules apply to this technique:

•If a filter is specified at the original command or previous --More--prompt, a second filter cannot be applied.

•The use of the keyword begin does not constitute a filter.

•The minus sign (–) preceding a regular expression displays output lines that do not contain the regular expression.

•The plus sign (+) preceding a regular expression displays output lines that contain the regular expression.

	In the following example, the user adds a filter at the --More--prompt to show only the lines in the
	remaining output that contain the regular expression “ip.”
	RP/0/RP0/CPU0:router# show configuration running begin line
	Building configuration...
	line console
