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
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: Dell#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: Dell# command | grep regular-expression |
except regular-expression | grep other-regular-expression | find regular-
expression | no-more | save
.
