Filtering show Commands

To find specific information, display certain information only or begin the command output at the first instance of a regular

expression or phrase, you can filter the display output of a show command.

When you execute a show command, and then enter a pipe ( | ), one of the following parameters, and a regular expression, the

resulting output either excludes or includes those parameters.

NOTE: The Dell Networking OS accepts a space before or after the pipe, no space before or after the pipe, or any

combination. For example: Dell#command | grep TenGig|except regular-expression | find regular-

expression.

except

displays only the text that does not match the pattern (or regular expression)

find

searches for the first occurrence of a pattern

grep

displays text that matches a pattern.

no-more

does not paginate the display output

save

copies the output to a file for future use

The grep command option has an ignore-case sub-option that makes the search case-insensitive. For example, the commands:

● 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 the search result above because it only searches for instances containing a non-

capitalized “ethernet”.

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

Displaying All Output

To display the output all at once (not one screen at a time), use the no-more option after the pipe. This operation is similar to

the terminal length screen-length command except that the no-more option affects the output of just the specified

command. For example:

Dell#show running-config|no-more

Filtering the Command Output Multiple Times

You can filter a single command output multiple times. To filter a command output multiple times, place the save option as the

last filter. For example:

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

expression | find regular-expression | no-more | save
