Using the 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 EMC 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 first 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 1/1/1.
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 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-regular-expression | find regular-expression | no-more | save.
