Concept Guide

• show run | grep Ethernet returns a search result with instances containing a capitalized “Ethernet,” such as interface

TenGigabitEthernet 0/1.

• show run | grep ethernet does not return that search result because it only searches for instances containing a non-

capitalized “ethernet.”

• show run | grep Ethernet ignore-case returns instances containing both “Ethernet” and “ethernet.”

The grep command displays only the lines containing specied text. The following example shows this command used in combination with

the show linecard all command.

Dell(conf)#do show stack-unit all stack-ports all pfc details | grep 0

stack unit 0 stack-port all

0 Pause Tx pkts, 0 Pause Rx pkts

NOTE: Dell accepts a space or no space before and after the pipe. To lter a phrase with spaces, underscores, or ranges, enclose

the phrase with double quotation marks.

The except keyword displays text that does not match the specied text. The following example shows this command used in

combination with the show linecard all command.

Example of the except Keyword

Dell(conf)#do show stack-unit all stack-ports all pfc details | except 0

Admin mode is On

Admin is enabled

Local is enabled

Link Delay 65535 pause quantum

Dell(conf)#

The find keyword displays the output of the show command beginning from the rst occurrence of specied text. The following example

shows this command used in combination with the

show linecard all command.

Example of the find Keyword

Dell(conf)#do show stack-unit all stack-ports all pfc details | find 0

stack unit 0 stack-port all

Admin mode is On

Admin is enabled

Local is enabled

Link Delay 65535 pause quantum

0 Pause Tx pkts, 0 Pause Rx pkts

Dell(conf)#

The no-more command displays the output all at once rather than one screen at a time. This is similar to the terminal length

command except that the no-more option aects the output of the specied command only.

The save command copies the output to a le for future reference.

NOTE

: You can lter a single command output multiple times. The save option must be the last option entered. For example:

Dell# command | grep regular-expression | except regular-expression | grep other-regular-

expression | find regular-expression | save.
