Dell PowerEdge FX2/FX2s - Manual (Page 28)

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: Dell#command | grep TenGig|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.
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”.
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
Command Modes
To navigate and launch various CLI modes, use specific commands. Navigation to these modes is
described in the following sections.
EXEC Mode
When you initially log in to the switch, by default, you are logged in to EXEC mode. This mode allows you
to view settings and enter EXEC Privilege mode, which is used to configure the device.
When you are in EXEC mode, the > prompt is displayed following the host name prompt, which is “Dell”
by default. You can change the host name prompt using the hostname command.
