Filtering Show Commands - Dell Force10 Z9000 Reference Manual

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 parameters listed below, and a regular
expression, the resulting output either excludes or includes those parameters.
NOTE: FTOS accepts a space before or after the pipe, no space before or after the pipe, or any combination. For
example: FTOS#command | grep gigabit |except regular-expression | find regular-
expression
display displays additional configuration information
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
show run |
grep
ethernet
show run |
grep
Ethernet
ignore-case
no-more does not paginate the display output
save 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: FTOS#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: FTOS# command | grep regular-expression | except regular-
expression | grep other-regular-expression | find regular-expression | no-more |
save.
returns a search result with instances containing a capitalized
"Ethernet," such as interface GigabitEthernet 0/0
does not return the above search result because it only searches for
instances containing a noncapitalized "ethernet"
returns instances containing both "Ethernet" and "ethernet"
