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 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.
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.
