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.

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 gigabit |except regular-expression |

find regular-expression

displays additional configuration information

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

searches for the first occurrence of a pattern

displays text that matches a pattern.

The grep command option has an ignore-case suboption that makes the search case-

insensitive. For example, the commands:

grep Ethernet

grep ethernet

grep Ethernet

does not paginate the display output

copies the output to a file for future use

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

returns a search result with instances containing a capitalized

"Ethernet," such as interface fortyGigE 0/0

does not return the previous search result because it only

searches for instances containing a noncapitalized "ethernet"

returns instances containing both "Ethernet" and "ethernet"
