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: 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 display except find grep 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 caseinsensitive. For example, the commands: show run | grep Ethernet show run | grep ethernet show run | grep Ethernet ignore-case 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" no-more save 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 CLI Basics 55
