Dell S3100 Command Line Reference Guide for the Series 9.100.0 - Page 42

Using the Keyword no Command To disable, delete or return to default values, use the no form of the commands. For most commands, if you type the keyword no in front of the command, you disable that command or delete it from the running configuration. In this guide, the no form of the command is described in the Syntax portion of the command description. Filtering show Commands You can filter commands using the show command to find specific information, display certain information only, or begin the command output at the first instance of a regular expression or phrase. Execute a show command and a pipe ( | ), and one of the following parameters and a regular expression to show output that either excludes or includes the specified 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: command | grep gigabit |except regular-expression | find regularexpression. except find grep 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: 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 TenGigabitEthernet 1/1. 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 Use the no-more option after the pipe to display all output at once - not one screen at a time. This operation is similar to terminal length screen-length except that the no-more option affects the output of just the specified command. For example: 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: command | grep regular-expression | except regular-expression | grep other-regularexpression | find regular-expression | no-more | save. Enabling Software Features on Devices Using a Command Option The capability to activate software applications or components on a device using a command is supported on this platform. Starting with Release 9.4(0.0), you can enable or disable specific software features or applications that need to run on a device by using a command attribute in the CLI interface. This enables effective, streamlined management and administration of applications and utilities 42 CLI Basics
