Filtering show Commands
You can lter commands using the show command to nd specic information, display certain information only, or begin the
command output at the rst 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 specied 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 regular-
expression.
except
Displays only the text that does not match the pattern (or regular expression).
find
Searches for the rst occurrence of a pattern.
grep
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
Returns a search result with instances containing a capitalized Ethernet, such as
interface TenGigabitEthernet 1/1.
show run |
grep ethernet
Does not return the previous search result because it only searches for instances
containing a noncapitalized ethernet.
show run |
grep Ethernet
ignore-case
Returns instances containing both Ethernet and ethernet.
no-more
Does not paginate the display output.
save
Copies the output to a le 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 aects the output of just the specied command. For
example: show running-config|no-more.
Filtering the Command Output Multiple Times
You can lter a single command output multiple times. To lter a command output multiple times, place the save option as the last
lter. For example: command | grep regular-expression | except regular-expression | grep other-
regular-expression | 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 specic software features or applications that need to run on a device by
using a command attribute in the CLI interface. This enables eective, streamlined management and administration of applications
and utilities that run on a device. You can employ this capability to perform an on-demand activation, or turn-o a software
component or protocol. A feature conguration le generated for each image contains feature names, and denotes if this enabling or
disabling method is available. You can enable or disable the VRF application globally across the system by using this capability.
Activate the VRF application on a device by using the feature vrf command in CONFIGURATION mode.
