Dell PowerEdge FN I/O Module Command Line Reference Guide 9.10(0.0)

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 following parameters, and a regular expression, the resulting output either excludes or includes those parameters.

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.
no-more	does not paginate the display output
save	copies the output to a file for future use

The grep command option has an ignore-case sub-option 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 0/1.
• show run | grep ethernet does not return the search result above because it only searches for instances containing a non-capitalized “ethernet”.
• show run | grep Ethernet ignore-case returns instances containing both “Ethernet” and “ethernet”.
