Command History

Dell Networking OS maintains a history of previously-entered commands for each mode. For example:
• When you are in EXEC mode, the UP and DOWN arrow keys display the previously-entered EXEC
mode commands.
• When you are in CONFIGURATION mode, the UP or DOWN arrows keys recall the previously-entered
CONFIGURATION mode commands.

Filtering show Command Outputs

Filter the output of a show command to display specific information by adding | [except | find |
grep | no-more | save] specified_text after the command.
The variable specified_text is the text for which you are filtering and it IS case sensitive unless you
use the ignore-case sub-option.
Starting with Dell Networking OS version 7.8.1.0, the grep command accepts an ignore-case sub-
option that forces the search to 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 that search result because it only searches for
instances containing a non-capitalized "ethernet."
• show run | grep Ethernet ignore-case returns instances containing both "Ethernet" and
"ethernet."
The grep command displays only the lines containing specified text. The following example shows this
command used in combination with the show linecard all command.
Dell(conf)#do show system brief | grep 0
0 not present
NOTE: Dell Networking OS accepts a space or no space before and after the pipe. To filter a phrase
with spaces, underscores, or ranges, enclose the phrase with double quotation marks.
The except keyword displays text that does not match the specified text. The following example shows
this command used in combination with the show linecard all command.
Example of the except Keyword
